I've connected to several Packet stations here in No. CA. which are
identified as "Wild Node".  Is this software unique to a particular brand of
TNC or what?  Just curious!

Glenn's 2Mbit/Sec data link project is in the ARRL Handbook, up to
about the '94 edition. It was really meant to be an exercise to stimulate
further experimentation, but it has been built and used by many. I think
FAR circuits still has the PC boards for it.

Unfortunately I can't answer your other questions, but the headphone
jack is not a standard hookup for all GPSs - indeed, if there is one I'm
not aware of it.  My Garmin 45 uses a strange proprietary round four-pin
connector; the Garmin 40 uses a round five-pin connector.

Hello and thanks for reading.  Recently, I just purchased an APRS Adapter
Cable to use with my PK-12 and Magellan Meridian GPS.  I also ordered a
power/data cable for my GPS shortly after the cable has arrived, and I have
not received that yet.  I am just concerned whether or not this cable will
plug into the power cord.  On the adapter cable there is a small cable, and
on the end where the GPS is supposed to plug in, there is a small headphone
type jack.  Does anyone know if this is a standard hookup for all GPS's?
Will I have to cut off the end and wire it into the GPS manually?

Please get back to me as soon as you can..  Any info can help!

I'm interested in hearing from anyone who may be using or is interested

Is there anyone operating APRS on 50 MHz?  If so, what frequency are you
using?

Have you downloaded APRS itself?  It comes with a bunch of text
documentation, including the beacontext format.  You can find it
at the APRS home page:

http://www-ns.rutgers.edu/~ksproul/APRS/

I know what you're going through - my first APRS station was a
DEC VT-100 terminal!

When you download the program from ftp.tapr.org in the aprssig directory
you will get plenty of help in the doc text files.

The format can also show your Power,height and antenna gain

If all TNC would just put 6 digit grid square in the Btext that would
help.    see WWW.tapr.org  to join the APRSSIG

(1) The SX-64 does not have a Casette port.
(2) The LOAD/SAVE commands default to device 8 (internal disk drive).
(3) The main ROM that tells it who it is is slightly different.
To use a cassette port version of Digicom with an SX-64, you
have to install the "missing" pieces, and switch ROMs with a C-64.

PS, there is a USER PORT version of Digicom floating around, but it
is truely terrible compared to what you'd expect from the Cassette
versions.

I recently tracked down a problem in an X1J node to a 512K EPROM I
programmed over two years ago.  I compared the source file with the EPROM
and found that the last two bytes in each page became FFh.  These are
locations 7FFE,7FFF,FFFE and FFFF.  I was able to re-write the program
into this EPROM, just for grins, and the four locations again agree with
the source.

I don't intend to use this EPROM again.   However, I would be interested
in hearing of similar experiences with EPROMS loosing their program.  The
chip in question had a paper label over the window and has been installed
in a TNC most of it's "life".

    I like runnig TNOS under LINUX. TNOS does compile under Linux using the
GCC compiler. You can do AX.25 PBBS forwarding, FBB style compression
forwarding, etc. Users that connect see something similar to a AX.25 PBBS.
Users connecting directly to the LINUX kernel may not like with they find.
Since TNOS runs under Linux, you get both TNOS and the Linux Multitasking
stuff. You can run scrips on Linux that montior TNOS and restart it when
needed. The combination of LINUX and TNOS are much more stable that xNOS
under DOS or Windows. To each his own.

You mean that the average user wants his/her hand holding and needs to be
told press this key or else. I used to run TNOS, but recently went
native, and I find it much more versatile than tnos. I can run netscape
in X as a mailer or news reader, or use pine, or tin, or elm, whatever I
want. Users can use mail, run programs play around with data (ie copy to
thier own directories and gzip it) before ftping. With tnos all they get
is a pms. If users don't like what they get tough.
You get what you pay for. Saying that I am always willing to help users by giv
ing them
guidance.

The software that comes with the KPC-3 is called Pacterm. You might be
better off getting something a little more sophisticated, YAPP at the very
least. If you want to work the internet gateways, you should get a version
of JNOS.

Hello,

In this months CQ I noticed that many packet modem ad also contained
the caption "Now does GPS"!

As a SWL-er with an interest in RTTY and other digital modes I was
wondering what this GPS does in the context of packet modems.

Would it be possible to retrieve your exact location by using one of
the modems, the correct receiver (Scanner radio?) and the correct
antenna, and probably a piece of software?

This would be great. Please could you let me know what they mean with
"Does GPS" and waht else I would need to create my own little GPS
receiver.

George:

        No it can't. The PK64 has essentially the terminal program
 and demodulation program burned into ROM that is loaded into the C64.
AFAIK, executables for the C64 can't run on INTEL platforms.

Might be possible - if you're a really skilled hardware hacker.
Otherwise, certainly not practical - and there's no sofware for an IBM

Hello there,

I'm new in this area, and would like to know is it a good idea to use
a 2 way digital RF modem for remote control helicopters? I would
like to build a large model helicopter with a something like a 386
processor in it and using RF modem to transmit far more command than
the converntional R/C controller and supply the "base" with the information
about the helicopter's current statas. Anyone know how fast a RF modem
will I need with or without GPS?

Thanks a bunch

There has been a lot of activity in the last 20 years of computers over
radio by the Ham Radio (amateur radio) operators worldwide.  In the early
'80s RTTY (radio teletype) was a popular signalling scheme (standard FSK
like modems use).  Later in the '80s and into the '90s packet-ham ("packet"
bursts) became popular.

From your posting I think you want to dig up information on the RTTY stuff.
You can look into one of the following USENET groups for more information
like this -- I cross-posted this message to the digital group and set
follow-ups to go there:

        rec.radio.amateur.antenna
        rec.radio.amateur.digital.misc

        rec.radio.amateur.misc
        rec.radio.broadcasting
        alt.radio.networks.npr: 1-7159

P.S.  I still have a RTTY receiver running at home collecting various
wireservices and stuff, and I used to run a packet-ham station tied into
a full bulletin-board system.

I measure mine by ear.  If I don't hear static, and my swept filter display

There is one major problem that the SS community hasn't come to terms with;
that is, the problem of operating next to a weak signal enthusiast.  I will
guarantee that you will stop all his fun.  The noise floor only applies to
distant stations.  Those receivers in the near field will be swamped by an
SS transmission.  So swamped that direction finder equipment can track them
down unsynchronized.

But I don't think we need a law.  The government should allow us bands of
use, and if the amateurs can't agree, then the bands should be given to
someone who can.  Laws are for lawyers.  I don't think we need either.

And the inverse can be true too if a SS station is operating next door
to a QRO contester. Due to the need for a wide open front end to pass
the band over which the spreading is occurring, the radio is subject
to overload and IMD problems from strong nearby signals. This sort of
problem is not unique, and is pretty much the rule with today's Japanese
radios, even for narrowband operators.

At least there is a solution to the narrowband weak signal enthusiast's
problem. The SS station can use a spreading sequence that stays out of
the weak signal segment of the band. Solving the inverse problem requires
some good RF engineering, but it can be done too. A sharp notch filter
can be applied to the SS receiver front end to knock down the offending
QRO signal while still allowing passage of most of the SS chips, which
of course are on other frequencies. The PAR filter is a trivial example
of the concept, applied to the pager crud infesting wide receive coverage
Japanese radios.

Actually it can. Using ETHERAX25 and WINPKT you are able to interface
Netscape etc over packet. I have some problems with Etherax25 routing
through an X1J node (or more to the point _not_ routing) but apart from
that it appears to be working ok. The source etc is available for it and
so no doubt some clever person could modify it to have a decent routing
table etc...

If anyone's interested it was available from the TAPR ftp site if I
remember correctly - last time I got using one of the various search
engines.

Finally I'd be interested to hear what anyone else is using for their
TCPIP networking. We are looking at changing the local system here from
FBB to JNOS and I want to try and get people using Netscape/Peagasus/Free
Agent etc over packet so it would be good to find out how others have
found such systems.

This is typical behaviour for ham radio networking.  Don't be surprised,
it's caused by a combination of low-speed links (1200 bps nearly
everywhere), extremely poor network engineering (hidden terminals,
simplex channels, etc), and a general lack of understanding among node
operators about how to do fixed routing, set parameters, and finally,
a "me first, to Hell with the hindmost" attitude of channel contention.

You're not doing anything wrong; that just the way it is.  Use the
telephone instead.

Further to that, when the "wild node" is on, any connection attempt to an
unallocated SSID is automatically routed to the node. If your PBBS is on -1,
it will still operate as such but anything to -6, if it's not already assigned

to a function, or any other non-assigned SSID will go to the KA Node. Mainly
useful in eliminating wasted packets from people trying to connect to
nonexistent callsigns or permutations thereof.

QST tested it in the big dualbander shootout issue. The BER at
9600 was poor. In fact none of the current crop of "9600 ready"
dualbanders actually had good BER. The Azden PCS9600D was very good,
but is 70 cm only. The IC820H was acceptable, though not great,
but is of course a big expensive desktop unit. The best choices
remain dedicated data radios, either the TEKK KS-900 or the
Kantronics D4-10 if you need more than 2 watts. Both of these
are excellent, and the TEKK is under $150.

If you're serious about packet, you'll dedicate a radio to it
anyway. Dual use never seems to work out very well. Every time
someone else wants to send you Email, or ftp a file off your
system, you'll be down playing on voice and not on the LAN
frequency. And every time someone tries to call you on the
repeater, the radio *will* be tuned to the LAN frequency
instead. So you'll always be missing calls in both modes.
You can't win. Soon you'll realize you need to leave a radio
on the LAN frequency all the time so that the network can
find you, and then you'll be shopping for another radio to
use on voice. Rather than going through all that, just buy
a data radio in the first place for packet and choose your
voice radio based on features you want for voice.

I was wondering.. has anyone made any software that allows you to monitor
PacketCluster dx-spots, announcements and similar things? So that you don't
need to be connected to the node. The common way is very unefficient,
because the cluster sends exactly same dx information to all stations. And
then all the stations have to confirm that packet. It would be much simpler
using UI frames by the box, sending all info two or three times to ensure
that everyone has got the info. And those who still didn't get the info
could send a sync packet to the cluster, like with FBB unprotos.

Now you cluster-writers, develop some common protocol for this UI-frame
dx-spotting so some other people can write terminal programs that work with
it! With this type of system tens of users could use the same 1200bps
radioport easily..

Think about it.
You receive fine.  Do not touch your "discriminator"
Output too hot?  Turn down your transmit audio level, reducing

There seems to be a growing level of APRS action here in the Colorado
Front Range area. I'm not set up to run APRS (yet), but would like
to start beaconing my position to other APRS users in the region.

So, the question is -- what format does the BTEXT need to be in?
I see lat and long information in there, but am not sure what the

I may be wrong, but as far as I can recall, it all works just fine as run in
the DOS VDM session mode in OS/2.  As I recall, the only problem is that
virtually all of these TNC programs are polling type programs.  Therefore,
they all hog the CPU for time slicing so badly that they become the ONLY
effectiuve program you can run in the OS/2 box that makes use of the
comm ports, when you use them.

That means, if you ae content to run just this program as your only comm
program, you will never likely notice the difference in the performance of
the whole box.

If you suddenly get brave and start to think about running more than one of
these polling programs at a time in your nice OS/2 box, you will get
badly dissappointed in the box and TNC's in DOS VDM sessions.

The onlu REAL solution to all this is SIO by Ray Gwinn, if you decide to
stay with DOS VDM stuff, or better still SIO and the OS/2 specific
multi-threaded TNC programs from HV9CVV, I think a couple others from
Europe and PAKET6, I read here a while back.

They are what you need for multi-threaded work in OS/2.

IMHO the "shame" belongs to the "public" network which has so little
capacity it can't even support 26 users at a time (the max a cluster
supports). Cluster doesn't operate efficiently to be sure, but rather
than banning it from the "public" network, and forcing all those Dxer
resources ($$$) into building a duplicate network, you should be tapping
those resources to upgrade the "public" network to have a decent throughput
so that a piddling cluster can't begin to bog it.

Not true in the UK - my licence allows me to use virtually any mode on

OK, and greetings.  Trying to put together an automated SAT sattion.
Have had the DSP-93 for about 9 months now and trying to get things
going.  Have the PACCOMM TNC and thought loading PSK and FSP modems
would be a lot easier than it seems to be.

Also, at least on my DX cluster @ 9600 - I seem to be getting much
better throughput on my MFJ/G3RUH combo then on the DSP-93 using the
FSK18 modem.  I have the thing tuned for 1Vpp input so I think it is
tuned as well as possible.  Using an ICOM 820H BTW.

Here's my question(s):
Should I get a DSP2232?
Will the TAPR TNC do a better job of Swapping modems and loading OBJs.
How does the 2232 compare to the DSP-93 or MFJ-G3RUH interms of
performance - don't want to shell out a grand and go backwards.

Thanks in advance for any advice or ideas you may have.

As I understand it, the long phase-out period planned for SA is to allow
the military to deploy adequate jamming techniques.

I've also heard that SA was turned off for Desert Storm, Haiti, etc.

DGPS will certainly continue to be necessary for high precision users such
as aircraft landing, and it seems that the White House decision will allow
the FAA to go ahead with its satellite-based wide area augmentation system
of DGPS for civilian (aircraft) users.

When will GPS/GLONASS dual system receivers appear in the consumer
market?  That would likely speed the day when SA goes away.  I've been
expecting some far-Eastern manufacturer to come out with such a box at a
low price to sweep the market.

Message-ID: <4k44th$[e-mail]>

Hi all, I've been doing some work here setting up a system ready to come
on-stream for our local packet users. Currently we are using FBB @1200bps
but I'm hoping to get some users to migrate to NOS & 9k6....

In preparation for this I have been trying out Etherax25 which seems to
work fine direct into a Nos box but there are problems for anyone who is
out of site of the BBS and has to use the local digipeater (which runs
X1J rel 2).

What happens is that if one attempts an FTP session to, lets say,
44.147.200.60 who is out of hearing range X1J (which we can hear) will
reply to an ARP request with that stations callsign. Now that's fine but
we need to connect to them through the X1J node - however what happens is
that Etherax25 attempts a direct connect every time :-(

I've tried setting the X1J node as the gateway in Winsock but this hasn't
worked either.

It seems to me that there are two possible solutions (a) have a decent
routing table that can be pre-configured for etherax25 (b) somehow set up
X1J to give it's own IP# & callsign as the system to connect to when it
rx's an ARP request for a station it know's about. It may already do this
but so far I've not figured out how :-( Presently I have manually set the
IP# & callsigns in the ARP table and the route table to no avail...

So the question is - has anyone struck this before &/or do you have any
suggestions for me????

Thanks in advance, de Luke ZL2JF.

They'll find whatever listener process you have hung on the port. It could
be sh, in which case they'll get the familiar $, or it could be a unix
menu system, a unix bbs, or any other unix program you want them to be
able to run. And many users can log in at once since a duplicate process
will be spawned for each of them.

If you just want to mimic DOS packet, the only thing you buy by doing
it under Linux is robustness, and the ability to use the machine locally
for other tasks while it does packet. Now that isn't bad, but it's the
same old tired paradigm that packet radio has been stuck in for too long.
Giving your users some real applications to use (like Doom) might make
them interested in faster packet modems. :-)

No; they'll still be able to turn it back on if need be.  The military
will itself use GPS a lot in any future wars, no doubt.  They certainly
plan to.

>What do all those GPS users do then?  If the SA will be elminited, will

Sure; DGPS with SA on offers considerably more accuracy than GPS (no D)
without SA, and differential techniques will still offer a dramatic
improvement over non-differential fixes, even with SA off.  The market
for DGPS will decrease, but not really by much IMO.

>I understand DGPS was developed to

DGPS and the various augmentation systems were developed to aid

It will depend on how much precision you need, and on how much
latency you can tolerate. As you may know, the "digital proportional"
control systems for RC are really analog systems with a varying pulse
position as the control element. The pulse doesn't move in steps, it
is infinitely variable in position (within its timing window), so
you get smooth control. With pure digital words, control becomes a
matter of steps, with the step size depending on the number of bits
you assign to each data word. 8-bit words only give you 255 steps,
and that may be too coarse for some flight controls. You may need
to use 16-bit words.

Latency is the other side of the coin. The larger the control frame,
the faster you have to send it for a given latency. Latency is the
time between commanding an action and the servos executing the action.
A 5 channel digital proportional system has a latency of about 10 mS.
At 1200 baud, and with 16 bit words, a 5 channel digital system would
have a latency of about 100 mS if no error control or acknowledgements
are included. Each additional channel would add another 13.3 mS to latency.
You really want to keep latency down or the controls will become "rubbery".
I'd say 50 mS would be the maximum tolerable latency. So you need to up
the baud to something faster, like 9600. That'll bring 5 channel latency
down to 12.5 mS, which is tolerable. Adding more channels, however, still
ups latency, about 1.67 mS per additional channel.

Now this is for a one-way system with no error control or acknowledgements.
If you want two-way action in packet fashion, other factors come into play.
You have to figure in Txd to include radio switching from transmit to receive
and vice versa, framing flags, control bits for the packet, etc. And you
now have to look at a latency that includes both a command and a response
packet because you won't be able to send a new control packet until a
response packet is successfully received. This will at least double
latency, so again you need faster equipment and faster baud. With 1200
baud packet, latency could be as great as 7 seconds. That would be a
disaster.

I think that if you want to use packet technique, you'll need two
independent radio channels, one for uplinking commands, and the
other for downlinking telemetry. I'd operate in connectionless
mode, IE UI frames, to avoid ACK latency, and I'd use at least
9600 baud for the uplink channel. Faster would be better, with
56 kb probably making a pretty nice system. The GRAPES 56 kb
RF modem will operate full duplex, but you'll also have to duplex
the RF of the transmit and receive converters. If you do that
crossband, you won't need a heavy duplexer.

Ron Raikes (WA8DED) had a terminal program called SS ("split screen")
that he wrote for talking to his firmware in host mode.  He only passed
it around to his friends. He did, however, freely publish the specs for
host mode with the hope that other programs would evolve. eSkay was one.

I had DED eproms in both my TNC-1 and -2.  The hostmode was identical
between them.

Very likely. If it is crystal controlled, then all you need is a
varactor across the crystal to turn it into a direct FM transmitter.

Or have a look at:

You need to get "ethrax25.zip". Try;

I'm on a MAC, so I can't be of much help on this.

please let me know.  From other messages, it looks like they cost

Heh, heh, it's nasty isn't it. What you have to do is modulate
*both* the VCO and the reference oscillator. Otherwise the PLL
loop filter will remove the lower frequency components of the
9600 baud modulation.

This is a little tricky because you have to use crossover networks
to only modulate the reference oscillator at frequencies below
the loop filter cutoff and still modulate the VCO above the cutoff
in order to maintain a flat response. You need an opamp with a RC
filter matching the loop filter cutoff in the feedback loop driving
a varactor you add across the reference oscillator crystal, and an
adjustable resistive divider to proportion the signal to the reference
and VCO varactors.

Kenwood didn't really intend this radio for 9600 baud packet so
it isn't designed properly to do it. (Frankly it isn't very good
at its intended purposes either, it has excessive phase noise,
the front end noise figure is pretty poor, and it overloads
easily.) But you can *make* it work. I helped a friend get his
going. (That experience reinforced my resolve to buy "anything
but Kenwood" for my own use.)

If you don't need frequency agility, a simpler approach would be
to build a varactor modulated crystal oscillator and substitute
it for the synthesizer in the 811A when you want to transmit 9600
baud packet. (You could diode switch it in and out with the TNC
PTT signal.)

I have found node-hopping to be very frustrating also, requiring a lot of
waiting and waiting and waiting and disconnects with varying degrees of
success.

Talking to a node manager, I found that although a particular node is on
the node list, it might not be available due to quality of reception and
other factors.

Also I found the best success off of "Prime Time" i.e., very early in the
morning or very late at night. During prime time, I have seen as many as
12 or more folks trying to use a node and it just bogs down when several
are requesting a list of bulletins or files. You can expect lots of
collisions and disconnects when this occurs.

On the Plus side I primarily use packet for the DX Packet Cluster which is
very efficient as most folks just listen waiting for that rare spot.During
a contest it too can bog down with frequent disconnects.

Good Packeting

HI HI!  It's just a harmless ham habit, Jim!  Also it's a form of
useful "inside" camaraderie.
Why say "ham?" Simply say, "radio amateur."

Every group has to have its jargon.  My wife, a non-ham, occasionally

   Many Q signals have meanings defined by treaty or other international

help if you don't speak the language of the person with whom you are

I have used my 736R for several years now on packet.
I originally used a MFJ - both the straight TNC and then a
multimode. Currently I am running a KPC3 from Kantronics.
I run via the data jack on the back of the 736R and all works well.
There is a mod for the 736R for 9600 rate but have not done that so far

Hi,

I have recently obtained an Icom IC-125 High Band PMR radio, which I
intend using for 9k6 linking. It is a 5 channel, diode-programmable
synthesised radio of the upconverting kind, so should give excellent BER
performance.

I believe I need to change crystal X2 to 40.2166 MHz and retune to get
it into the 2M band, and fm X1 (21.4 MHz) with a varactor for
modulation.

Does anyone have any experiences of this set, and I would *really*
appreciate a copy of the circuit diagrams etc.

Here's hoping ;-)


Steve

The BEST radio for 9600 BPS Packet IS the MOTOROLA MITREK!  This radio can be
had for $50.00 and the mods are easy!  There is a mod here in Southern CA
that allows you to retain the voice capabilities of the radio!

One draw back to the Mitrek...it is a crystal controlled 4 channel radio.
This would be the choice for dedicating a radio for 9600 Packet.

BTW, I like the UHF Micor.  Cheap, only uses one crystal per channel, easy to

I have used a rf-concepts 170 watt amp on packet for many years. There
is no problem using amps on packet. But if you did get an older amp
that was a little slow on the relay switch, you can adjust most tncs
in the command set to delay on the data sent out to allow for the amp
to get keyed all the way before data is sent. But I had no problem and
didn't have to adjust anything with the amps I have run.

Yes and yes. T/R switching time is a factor, and you have to increase
Txd to allow for it. Too much Txd slows down everyone on the channel,
so you need an amp with fast T/R. And yes you can do it because you can
get fast amp T/R with PIN diode switching. (For 1200 baud, even relay
switching is fast enough.)

Beware of the response time of external PAs with RF-sensed T/R switches.
While they're normally pretty fast, you may be surprised at how long
some can be, particularly on the receive-transmit transition.  You
may want to attach the T/R switch on the PA to the radio/TNC to eliminate
this component of delay.

Right. I agree completely. Don't depend on RF switching, hard switch
it. That's also why I use the "sideways transformer" circuit instead
of a RC circuit for keying PTT on "leaky" PTT HTs. It gives a harder
and faster switch.

     The timing can be a problem but most amplifiers are fast enough
that an increase in TXDELAY will let it work.
     The biggest problem tunning high power is that you won't hear
as well as you talk.  That means that you will cause colisions that
aren't necessary.  One of the things that a lot of folks don't do is
run a preamp along with the PA.  This would at least let them hear
stations far enough out that some colisions would be avoided.  I'v
even heard of someone running 150 watts into a 1/4 vert.  Not too
great for the rest of us.

There's already a suitable protocol available, it's the Pacsat
protocol. All we need is for a cluster author to implement
Pacsat protocol in his system and users can use the already
available Pacsat ground station software to receive the spots
and uplink spots to the cluster. This method can decrease
LAN traffic by up to 26x over the way cluster works now.

The Pacsat broadcast protocol is heavily file-transfer-oriented.
While the principles of operation will surely be the same, you will
need enough modifications to make existing Pacsat software useless when
receiving DX spots.

The proposal I detailed in another article operates similar to Pacsat
broadcast, but without the binary header and dedicated PID that make
it difficult to implement in existing systems and difficult to monitor
by existing user software.

I know this has been done. In fact, here in Oulu we have a talking dx
cluster, which monitors the cluster announcements and forwards the dx
spottings on FM voice transmission. No terminal or cluster client
program, however.

UI monitoring may be efficient when you think data communications
alone. However, it can easily lead to an unfortunate situation where
nobody SENDS any DX info to the cluster. Everyone just listens...

Many people tend to use the DX cluster systems for monitoring only.
One should remember, though, that the cluster is only as good as the
DX spots entered to the system. There should be a way to limit the
DX infos heard... maybe 10 spots for one sent to the cluster. If the
regulations didn't forbid, the spots should be encrypted to each
client with a different key. ;-)

Well, the two connection modes could, of course, be combined, and thus
both efficient monitoring and announcing DX info would be possible.
Just a thought...

The PACSAT protocol is heavily file-transfer oriented.
It expresses its packets in terms of "file ID" and "relative position
within file".
This does not lend itself well to the purpose of sending volatile
messages that are generated over time.  This was already very apparent
when the PACSAT protocol was extended to send directory information.

Of course.  Keepalives are not very useful in any case.

Here are a few uses for APRS:

Marathons       (tracking runners, ambulances, etc.)
Sky Warn        (tracking of reported hazardous weather, and the spotters that make t
hese reports)
Weather Ballons (track and finding weather experiments)
Car theft       (be nice to know where your car (FULL OF RADIOS) is off to....)
Weather         (APRS has the capability to display current weather if the station is
 equiped with
                a weather station.

Some areas have alot of mobile activity and it can be fun watching where they
are going...

Give it a try, think your be pleasantly surprised.....

This software is available on the net and many HAM BBS.

By the way Nice Job Bob (WB4APR)!!!

The answer lies in 97.109e, your station may operate under *automatic
control* (same as ordinary operation of a repeater, other than during
phone patches) on the 6m and higher bands when using AX.25. The station
must have some automatic means of limiting transmissions in case of a
fault. The regular timeout timer in the TNC will serve.

in sequence-numbered UI frames.
  I really like his idea of a simple command to the Cluster meaning "I'll
monitor your UI frames, don't send me spots directly."  That would greatly
reduce channel loading.
  Let me assure you all that sequence numbering the UI frames is NOT
necessary.  The PROPLOG program I'm "finishing" gets along just fine
ignoring message sequence numbers.  It merely matches the time, frequency,
reported call and reporting call contained in all DX spots, and rejects
duplicates.  Nothing has to be added to the present message content.  I've
never noticed a problem in over two years using this approach.  I would,
howver, like to see the node ID, where the post entered the Cluster
system, added to the user messages (it's in the internode messages).

It must be nice to live in an area where there are no collisions between packe
t
transmissions. :-)  If you don't have a sequence numbering scheme, users will
never know if DX spots are missed due to collisions.  I think it's a very
workable scheme that will go a long way toward relieving some channel congesti
on.
I agree that the originating node callsign should be included so that the user
software can filter DX spots if desired.

When you don't use sequence numbers, there is no way your program is
going to know it has entirely missed a DX spot.  This may not seem to
much of a problem on a channel where 20 users are connected and you
see everything many times, but when a new protocol is adopted and the
cluster is sending every spot only once, it will not work.
(each user will see only a fraction of the DX spots, depending on the
fraction of UI frames that he happens to receive correctly).

The word that "when using this new method you don't get everything and
you might miss that important spot" is going to spread quickly, and
everyone will go back to connected mode "just to be sure".

This, while "duplicate detection" is nice to have and will save bandwidth
when you can receive multiple DX cluster nodes, it is not a replacement
for sequence numbers and retransmission requests.

Ok, great stuff guys .... I have had two replies telling me, essentially,
to put up  a decent digital repeater....

Well I have been  telling the local amateur community this for the last
five years that I've been living here and to date the response has been
somewhat less than enthusiatic. What's more they even seem to want to get
in the way of such a project, let alone help. Finally there are three
voice repeaters in the local area that between them all get probably
1/25th of the activity that the two data frequencies do and yet are
definately sacred cows when one suggests the possiblity of using one for
data, even if just "sharing".....

So I hope you've got the picture - if anyone has an intelligent and
useful answer for my original post I'd be pleased to hear it. At the
present time I _have_ to work with this bloody digipeater if I'm to at
least ween some of the users off FBB and on to something a bit more
networkable :-|

Ah.... finally something I can answer.... :)

Computer are operating at high speed (33/40/50/66/75/100/120MHz/etc),
and that is easy for them to create strong RF noise around them, the
best bet is to create a grounded metal casing around your computer,
and get a longer cable to connect to your computer. but as your computer
is a note book, you can't really shield the notebook without losing the
use of it, so you might want to build a metal shield that act like an
antenna that receive the RF noise and channel it to the ground, and get
a REALLY long cable to further reduce the interference.

>Does anyone have recomendations for eliminating RF noise from such an

Can't really eliminating the noise, but at lease reducing......

Glen:

Start by using an outdoor antenna, with shielded coax cable to the scanner.
Make sure the shield is grounded!  Try moving the radio to different parts of
the
room.  Use high quality "shielded" cables for your modem, printer, external SC
SI
devices, etc.  Make sure your computer and other devices are using three prong
 plugs
with a grounded three prong outlet (make sure it's grounded).  Use those iron
donuts
on your keyboard & mouse cables (available at Radio Shack).  If you still have
 a
problem, try making a foil sleeve, ground it, and wrap it around most of the s
canner
body.

Since you're using a notebook, it'll be harder to shield and suppress
the interference than it would be for a desktop machine. The same
techniques apply, however. The objective is to turn the housing into
a Faraday cage that traps all the unwanted RF inside the computer
and doesn't let any out to get into your radio equipment. A Faraday
shield requires a completely closed conductive enclosure to be effective.
Wire mesh can work, conductive sprays are available, etc. Any cable
that enters or leaves the Faraday shield must also be completely
shielded or fully suppressed, don't forget the connector hoods, they
should be metal too, not plastic. If you are using external power
for the notebook, the power lead should be suppressed with a ferrite
core.

You should also shield your scanner. Most of them typically aren't
fully shielded and can pick up nearby signals without an antenna
directly into their circuits. And of course you should use an outside
antenna, located as far from the computer as possible, and fed with
well shielded feedline. In fact, try this first. It may offer sufficient
protection without requiring you to disassemble and re-engineer your
notebook's shielding.

I think you will be very surprised to know
how VERY slow Electrons move through copper.ie
from one end to the other.  and if using AC they NEVER make it. :-)

Does anyone here know of a mod for the Kenwood TS440S to make
it use true FSK keying for RTTY use? The Hal P38 instruction
manual mentions the shift voltage to setup for this radio. In
all of the Mod articles I have seen there has never been a
mention of modifying this radio for FSK use.

Message-ID: <4kf7lb$[e-mail]>

Hi gang. I am running a BBS using FBB and BPQ and I would like to limit the
routes that the node picks up. There are a couple nodes on the system here
that don't conform to the parameters we have set up and I would like to keep
their node broadcasts out of the BPQ node table as they force connects to
unstable routes. Is there any way of doing that. I have gone through the docs
and couldn't see anything like that. The other programs I am familiar with,
TheNET and JNOS, have commands that keep out unwanted routes but I am not sure

how to do it with BPQ. If you know how, please email me with any info on it.

Thanks and 73.

When SA is turned off, civilian receivers work better. The thing to
remember, however, is that as long as the satellites are capable of
SA, and they will be until the current batch is retired at least,
the option to turn SA back on will always be present. Therefore,
DGPS is still the smart choice for anyone depending on a high
degree of positional accuracy from GPS. DGPS is also capable of
higher accuracy than even non-SA ordinary civilian GPS. I don't
see it going away.

Date: Thu, 11 Apr 1996 21:04:32 -0700
Message-ID: <[e-mail]>

I was trouble shooting a problem with my PK88 today and noticed that
the PK88 has as the means to use an external modem via pins 13-16 in
J1 (passing CLK, CD, RD, and TD respectfully).  Jumper(s) JP4 must be
set to "B" position to use the external modem.  This would explain
the additional values for "HBAUD" above 1200bps mentioned in the manual.
Although, I cannot find any mention of using external modems in the
manual.

I was curious if anyone has ever made use of this feature?  Has anyone
use the PK88 as front-end for a higher speed modem (2400 or 9600bps)?

Sir,

It's still available.  The IBM/DOS Broadcasting Radio Station Database
Program for Longwave, Mediumwave, and Shortwave.  Over 4,000 records
included already.  The program is completely read and write.  Records
can be added or changed.  Sorts in many different formats both on your
screen and printing.

If you would like a copy of the program, send your request to
"[e-mail]".  Please include your MAILING ADDRESS. For example,
your street number, city, state and zipcode.  Also include your Email
address.

The program will be sent to you via Email probably within 24 hours if
not sooner.  If you request the program and haven't received it in that
period, check back with me..

Remember to send your address.  Requests without a mail address will no
longer be acknowledge to save time on the internet.  In the past,
requests without an address were reminded with a message.  Usually, the
reminder went unanswered anyway.  If it was, the reply was sometimes
very rude.

This program is free!  Everything works.  It has many features and they
all work, not like shareware where some of the features work and others
don't.

You address will be kept confidential.  I will be sending you a first
class letter later explaining another full featured Database program
available. It's very big!

Do you *really* need a cross-over?  I suppose you're trying to avoid
a hump in the response around the loop filter cutoff frequency, but
how much of a hump is really produced?  Afterall, the loop filter
cutoff frequency manifests itself as a low-pass filter cutoff for
reference modulation, and a high-pass filter cutoff for VCO modulation.
In actuality, the "filter" is really the entire loop, and it already
provides the cross-over function.  What you need is independent
modulation level controls for both the reference and VCO.

The MX*Com documentation about two-point modulation doesn't mention
the use of a cross-over.  I suspect that it simply isn't necessary in
any reasonably designed PLL.

   APRS is a system developed by Bob Bruniga, WB4APR (hope I have the
name and call right without looking either up) for automatic reporting
of the location of a radio station using the packet protocols.  Bob
has written programs and developed protocols through which GPS
receivers, computers and packet radio can be associated so that
positional information is sent, received, listed and plotted on
maps.  It is helpful if all the elements of the system are
available to all participants, but not necessary.
   It is basically for fun, but you can see it can have many uses.

And finally, this is what it is, and like the autopatch, it can be
useful in some circumstances, such as public service events and
emergency response situations where it is beneficial to keep track
of where all resources are located. It's also useful for tracking
balloons, something a number of amateur groups are actively doing.
Fixed stations even have a use for it. It can be used as a smart
automatic propagation beacon, showing graphically where and when
the band opens to certain areas. I find this the most interesting
application of all.

   I think you have just thought of two of the many uses.  People

One of the things you learn about that guy is, that he hates everybody, and
nothing measures up to his accomplishments.  It's rather boring.  But if
you do a search of his name in Deja News, you will see that maybe .05% of
his contribution is something positive.  The rest is constant whining...

APRS originally served the same purpose as the military TADIL system (Tactical
Data Information Link).  The system is used to provide Track positions of
combatants.  For example the E-3 at altitude will use HF to drink in Air, Sea,
and Land targets, and relay the data via UHF to the Command and Control
Element.  The difference is that the TADIL system has one master, and many
slaves.  Amateurs refuse to be a slave generally (notice the Node count is
approximately equal to the number of packet station) and this system of the
master polling each unit for Tracks, would be a sure loser.

Trying to translate this into something that would be useful in a community
is difficult.  Here in Oklahoma there was some thought to incorporating it
into the Tornado Alert system.  It doesn't work well.  The storms are too
dynamic, and choosing any frequency as the storm frequency attracts everyone
to that channel, with none going radio silent.

Without a polling feature by a master, the system breaks down.

If people are willing to define a protocol, where a central node (Net Control
Station - NCS) polls the Participant Unit (PU), and has a Pop-Up mode for
joining the net, then the system may serve an useful purpose.  At that point
it could be used for Data Link.  For example in OKC there was several Ham
sites during the bombing that relied on voice to order supplies, and state
status.  The same for Tornado tracking.  Unless it's organized, it's worse
than what it is trying to replace.

Every profession and hobby uses phrases that form a verbal shorthand. For
you
to flame anyone that uses a Q signal in a QSO shows a remarkable lack
of respect for the tradition of amateur radio. As for "10-4 Gud bud", Why
not write a triade about those who use 11-meter skills. For one, I suggest
you return your license. Your not going to enjoy working us Bozos.

FWIW the Q codes have been around for a long time. I have a UK
Government publication which dates back to 1946 listing loads of
Q-codes. The book mainly lists codes for aeronautical use.

There are some interesting anomalies, such as QFO, which means 'you may
land immediately' where one might suspect it ought to be 'go away' :)

Let's see...we are talking about the use of language here.  This guy doesn't
like the use of Q-signals because he thinks they sound ignorant.  This is
the same guy who uses phrases such as "Talk like an ass" and "ignorant
bozos."  Interesting indeed!

please send me a copy, too. I would also like to know why we can┤t simply use
an old NE2000 card and slow it down to 2MBit/sec oder even less. I think I rea

something about that on N6GN┤s pages, but he only that it won┤t work, not why.
Perhaps if we know the problem we could try thinking of a solution.
I┤m also trying to think of a simple low-cost solution. GUN plexers are to
expensive and too difficult to get here in Germany, I┤m currently trying to mo
dify
old sattelite receiver LNBs to transmit. It seems as if we could pull the LO t

beasts into the ham band w/o problems. It can be modulated directly. The usuab
le
bandwith is about 900 KHz @ -6dB . Sure, that┤s not enough for 2MBit/sec but p
erhaps
I can do better. Suppose there was a possibility: What modem and what interfac
e card
would I use? If I could connect the output of an arcnet card more or less dire
ctly to
the modulation input and on RX side more or less directly to the baseband outp
ut of
an old sat receiver a 10 GHz high speed link would cost effectively nothing.

Hmm.. Sounds very interesting!  I have access to lots of Arcnet cards
and I don't really mind killing them, so I'd love to hear about this.

If any more information is found, I'd love to hear about it.

There is a program called RXCLUSTR written by a Swiss SWL I believe that monit
ors
a Cluster frequency and grabs all the spots,  displaying them and storing them
away.  This solves the problem of not having to be connected to get DX spots.
However you can't submit any spots.  I got the program from one of the major
FTP sites,  maybe UCSD.

The best solution would be to come up with new Cluster software to implement a
high level protocol to get rid of the inefficient channel usage.  The problem
is
that so many users out there are just using a dumb terminal!

Gerry,

Yes someone has.  He (my apologies, I forgot his name) suggested
looking at 97.109e that does allow for for automatic control of a
station transmitting third-party traffic (in digital packet).  However,
this applies only to 6 M and shorter wavelenght bands.  Nothing is said
about HF packet, however, my station is operating on VHF (2 meters).

Thanks for the reply.

I agree with Gary, the Analog Devices assembly language is easier to
learn.  AD uses "an algebraic syntax for readability and ease of coding"
(a quote from AD).  So, for example, instead of using some MOV command, you
use an assignement with an equal sign (AX0 = I4).

The EZKIT Lite does NOT come with a programming manual.  You will have to
order "ADSP-2100 Family Users Manual" (free) from Analog Devices.  Another
handy, but not required, book is "Digital Signal Processing in VSLI" by
Richard J. Higgins.  This latter book is a good DSP reference as well.

Two other handy books by AD are "Digital Signal Processing Applications
Using the ADSP-2100 Family, Vols 1 and 2".  These books contain some
applications for the 21xx.

Analog has a web page http://www.analog.com.  In the support section
there is lot of useful info and samples.  I used their sample of the
optimized decimation in time FFT (with some modification) in a spectral
analysis project for a DSP class.

Oh, and one more thing, AD does NOT give you a decent debugger with the
EZKIT Lite.  But what they do give you is a pretty nice simulator that
will run on a PC.  I managed to debug the FFT using the simulator.  After
that I was able to use the few real time tools that they do give you to
debug the software on the board.

It would be nice if there were some Ham applications for this board.

Well, several of you have said it, but I will put in my $0.02 worth:  The Anal
og Devices EZ-Kit
Lite will probably be your best bet.  TI's board only has one I/O channel, whi
le the EZ-Kit Lite
has stereo I/O.  Also ADI's assembler is so easy to use that it doesn't seem l
ike assembler.
All the stuff is there to write your own proms to if you make something neat w
ith the board.
(save of course for the actual prom programmer).

One more vote for ADI.

I've worked with both the Analog Devices and the Texas Instruments DSP
products.
In terms of real-life application development, there is no question that the
Analog Devices performance is better (IMHO).  However, if you are strictly
interested in _learning_ DSP theory and operation, I feel that the Texas
Instruments DSK is the best way to go.
I am currently using the TMS320C5x DSK for a ham radio application.  I am
trying to develop a stand-alone packet controller (including AX.25, P-CSMA,
modem, and error checking/recovery functions)  Due to limitations on the DSP,
most of the non-time-critical stuff will probably end up in the PC application
S/W.
TI offers excellent user support, and it's _FREE_.  Analog Devices only gives
you the time of day if you promise them a 20k units/year production order.
Also, most of their documentation comes at a steep price, unless you are
really into downloading everything from the network.
For functionality and operation, the AD2100 family kicks the TMS320 family's
butt.  But for user support and development, TI is the good-guy in town.

Also, don't forget the big questions when choosing a platform:
        Cost?
        Performance?
        Functionality?
        Compatibility?
        Reuse?
        Reliability?
        .
        .
        .
        etc.

I've got one of the Analog Devices EZ-KIT LITEs, and am very pleased
with it. It should run all the software in the ADI applications books,
which includes filters, DTMF, etc. It has a 33 MIPS ADSP-2181 with
plenty of on-chip RAM, and a stereo CODEC. One's own code can be put
into EPROM and used to replace the monitor code. All the bus signals are
brought out to two 50-pin headers (you have to solder your own in,
though). It's very good value.

Thou I would agree that the protable drive are more rugged (*usually*),
that the spin down feature is not automatically enabled, you need a program
to enable the feature. I have a program that will enable this function on

Does anyone know if a newsgroup exist where HDTV issues are discussed?

     If not, I figured our amateur radio newsgroup would be the best place to
post a technical question about the impending HDTV broadcasting changeover...S
o
here it goes....

    The projected cost figures of the HDTVs are extremely high compared to
current TVs.   I suspect the majority of american families will be unable to
come up money for the HDTVs.

     Since HDTV transmissions will be incompatible with the current NTSC
transmissions, is it possible and likely that TV accessory manufacturers will
come up with an economical convertor box to convert HDTV transmissions into
NTSC signals, so that HDTV broadcasts can be viewd by regular NTSC TVs?

Q-1.  What is the maximum range?

Q-2.  What is the maximum data rate?

Q-3.  Why RS-232?

Q-4.  Would Light be better than RF?

Q-5.  What is your budget?

The first question pretty much drives the whole equation.  If you want
to go 10 miles, you have a problem.  If you want to go 10 feet (meters)
that's a lot easier.

You get the idea.

There are good products all over the market for 19.2 kbps full duplex
(Spread Spectrum) in the 900 MHz and 2.4 GHz bands.  Then there's the
1.5 to 2.0 Mbps stuff in the 2 to 4 GHz band.

Hello -
I will be setting up a portable hf station near Wateford california on
April 18th, and
19th in order to test G-tor with a military NVIS antenna system.

If you have an HF data station located within 400 miles of the
Modesto/Waterford, California area I would like to hear from you!!..

My station will consist of the following:
Sunair military HF SSB radio model GSB900DX running 50 watts
into a military NVIS antenna model AS2259/GR that has also been modified
to allow better performance on  the 1.6 to 4 MHz segment.

The station will be on generator power and I also plan to leave it up and
running in an un-attended
mode on the 80 meter band with a mailbox enabled.

If you are interested in running NVIS tests with me during this time
period, please e-mail me

Sincerely,

Recently I became interested in chatting with other folks about various
aspects of amateur radio and digital communications.  My teenage
daughter, N0OWM, is interested in chatting with other teens.  We have
access to the Internet both by Amateur Radio (a local gateway) and via an
account with a local ISP.  After a little research, confusion resulted.
Maybe you can set us straight....

1.  Is there a difference between CHAT of JNOS and the so-called converse
nodes?  Are they the same as IRCs?

2.  How can available IRC servers that specialize in special interests be
identified and how can channel numbers be determined?  Can anyone point
to some good IRC servers for amateur radio and teens?

3.  There is some special client software available for Windows.  It it
necessary or can I simple TELNET to a particular server and channel?

In advance, I thank you for your suggestions.

300 bps will have about a few seconds of delay before you can send the
next command, no, it not good, I'm considering FOUR 9600bps R/F modem,
2 or T/X and 2 for R/X. the theory here is like a set of modem constantly
getting the information from the plane, and a set consantly sending control
commands to the plane, it I believe, connectionless mode. WHY the hell would
I recommand this? it because if you are using a set of modems (2), you will
need to recieve the data from the plane before you can send the command
about the control, and that creates a lot of delays. Also for good controls,
each channel will take about 8 bit, and that will take a mighty long time to
transmit over the 300bps modems.

>Anyone have any ideas on a radio system that would meet these requirements?

GRAPES modem seems to EXCEED the demand I put out, but they also EXCEED
the total $$$ I have in my bank account... how sad.... :(
GRAPES can go about 56Kbps.

My plan is a bit different from yours, I plan to build a MAMMOTH sized
coaxiel chopper. with 2 to 4 engines (single cylender, so it cheaper)
GPS, tempature sensor, altitude sensor, ground height sensor, cameras(3),
and MORE! The control *station* will have a Thrustmaster joystick, throttle,
and CH rudder! God, this gotta be fun to fly!

Wrong ! The DF9IC modem works like any other modem : you have to plug it on a
TNC or any packet-radio controler like this (USCC Cards, RMNC, etc...).
As far as I know, it uses NRZ signals (G3RUH uses NRZI).

take a look at http://www.baycom.de, the BayCom Web pages and check for a
local BayCom distributor. If you can't find one, I'm the French one and will
help you getting the DF9IC modem.

Hmmm, 2k4 isn't worth now. Turn directly to 9k6, I'm sure you won't regret it
later :-)

What about your own site that use digital connectionless link? 4 GRAPES

Hummm, I think I saw something like that on Beyond 2000 (Australlian
TV show, broadcasted in Canada, and maybe US). I suspect that they
use APRS because they did NOT use the buzzing word.. "GPS" and
the map... ugh... is very vetorized, very few vector too... :)

Weird, is GPS related to APRS? from all I read here, it don't seems to
be, so why????.... And how accurate is APRS? 1 metre? sub metre? 1 cm?
sub-cm? 1 Micron? Sub Micron? :)

I'm running a recent TNOS on Linux. Users that connect via Ax25 can't
telnet even though (I think) they should have permission (set in
ftpusers?)

I'm sure this a known feature. Can someone enlighten me to its purpose?
I'd like to allow ax25 users access to various hosts on my network and
this feature is preventing me.

There also seems to be a whole slew of ways to connect to TNOS, each with
slightly different behaviors, permissions, and semantics. Is this so, or
is it just me? And is there anywhere a description of the different ways to
connect to a NOS/JNOS/TNOS system and the associated quirks/features?

There are a number of such programs available.  One good one is
RxCluster.  I think it's available at the ARRL BBS.  It just monitors
the spots going out to others and puts them on your screen.  Also checks
for needed countries, etc.

Actually PC/Flexnet has a driver that emulates the packet driver interface.
As far as I know there is another driver out there that implements the
winsock interface using a packet driver.


PC/Flexnet runs under DOS but is currently being ported to Win95/NT. And it is
for free....

You are in luck - the TS440 doesn't need any modification for FSK.  The
FSK-T and FSK-R data lines appear on the 13 pin plug on the back, along
with the analog connections needed for AFSK keying in the "FSK" mode.
That plug is a bear to find and to solder, but the results on FSK are
fantastic.

Now, if you can, return the favor.  Please tell us how to fudge the
internal microprocessor so I can select the 250 Hz 455CW-N filter for CW
and still have the 500 Hz 455CW on FSK mode.

    Hello, dear friends!

  Excuse me for a stupid question, but I didn't find any explanation
of commands TNC's in KISS mode.

  The problem: I use KPC-9612, dual port Kantronics TNC, it works good,
especially on 9600 bps in terminal mode. To use some special software
that needs to switch TNC in KISS mode (for example TFPCR with GP, or
WINPACK) I prefer to use 9600 port, BUT (!) as a default TNC uses 1200 bps
port. In manual I found command PORT 1/2, but this command switches ports
in terminal mode and make another default port in terminal mode. In KISS
mode TNC always use 1200 bps port. I know, that G8BPQ software can control
TNC in KISS mode, and it really does!

  But how can I switch ports in other packet programs?

  My callsign: UA3DVU, packet address: [e-mail]

I don't know the KPC-9612, but most 2-channel TNCs allow channel selection
in KISS mode on a per-packet basis.

The channel number is coded in the upper nibble of the first byte sent
to the TNC (after the opening flag).

E.g.:

   C0 00 xx xx xx xx C0   -> send xx xx xx xx on 1st channel
   C0 10 xx xx xx xx C0   -> send xx xx xx xx on 2nd channel

You will need to check your host software to find out how to switch
between sending "00" and "10" as first byte.

When you start boasting frequencies...  over here in the Netherlands,
packet activity is on 144.620 - 144.675 and 430.600 - 431.000 MHz.

I have been using NET/Mac for years and just ran into a new
problem. The local ax.25 BBS put an MSYS port on the freq
where we have been running ip. He turned on the tcpip options
within MSYS.

The problem is my NET/Mac can send smtp messages to the MSYS
station but cannot seem to understand the closing message from
the MSYS station. The msg passes, my station does not get an
ACK and sends the message again. I had 13 copies of the same
smtp message on the MSYS BBS.

The problem seem unique to NET/Mac. The JNOS stations do not
seem to have this problem.

Anyone know of a fix?

Hello all,

Does anyone out there have any idea where I could get hold of a
program called 'Packet Tracker'.   I read about it in an ARRL
publication on higher speed and different packet applications, I
think.

Going by what is written in the book, it was originally written for
the Mac, but at one time I am sure I had a copy on my computer, but
never got around to checking it out, and naturally it has disappeared
from the HD.

Basically it monitors packet activity on a channel and displays it in
a graphical form, showing what stations are connected to where, doing
what and to whom.   It can display stats on the channel activity,
highlighting retries, collisions and throughput.   Seems to be a very
interesting program, but I just cannot lay my hands on it anywhere.

Can someone help??   If you can, please send me the info via this
newsgroup and/or e-mail.   I wrote a message on packet and got a
deluge of mail, all asking if when I get hold of it whether they can
also get a copy, so there are a few people here after it.


Here's hoping,

We have experimented with using repeaters for extending ranges.. and it
works quite well.  You just have to allow a longer txd value... and that
is purely experimental due to different repeaters having different
delays set.  You'll also have to fool with axhang, but this isn't quite
as critical as txdelay.

Really 1200 is going to be it without modifying that repeater.  2400 is
possible without any mods to radios or repeaters, but your tnc will have
to be modified.  I've seen one tnc modified for a dedicated link to 2400
and it was a PacComm Tiny II and on that model all that is required is
replacing one crystal that in effect doubles the clock speed and gets
you up to 2400 baud.  The other tnc was modified the same way.  I don't
know if this will work on other makes, or if 2 different makes can talk
to one another once modified.

To find this out, I'd look at the NEDA home page.  I don't know the URL,
but connect to http:\\www.yahoo.com and search.  You will find it from
there... I've done that before.

Good luck.

Hello all,

What is involved in using a voice repeater to 'digi' or extend the
coverage of packet radio?   Is it just a matter of setting the radio
onto the appropriate channel and split and going for it?

Reason is we have a virtually unused repeater in this region of
central NSW in Australia, but absolutely no digipeater facilities
around within useable range.   There are quite a few potential packet
operators around this district, but the area is fairly large, with
many high ridges spread around which makes a mess of reasonable
contact with most people by packet.   We thought of possibly using the
voice repeater to allow contact over a wide area with packet and also
tying a packet bbs into all this.

Another point with all this is that it does not tie us into a fixed
1200 baud repeater.   Someone could use 1200 baud and it would
hopefully work, and tomorrow we could experiment with 4800 or higher
speeds without having to install more equipment at the site.

Anyone have any ideas on this??   What settings, parameters etc would
have to be changed from normal operations??



Cheers,

Solved the problem with my cable.  After much closer inspection, I
discovered that the wire (white) leading from the tip of the smaller jack
(used to control the PTT) had a break in the insulation.  Cabling worked
fine without the housing (Al), however, if you place the housing on the DB-9
connector, this break in the insulation caused a VERY LOW impedance path (in
fact none :)  ) to ground.

Snipping the wire, stripping back insulation to expose fresh wire , solder,
and wrapping in electrical tape solved the problem. Overkill??? Maybe, but
rather be "safe than sorry".  Thanks again for the help.

I forgot to mention, that when using this cable, the HT is keyed to
transmit.  No command is given to the TNC to transmit and I have not
yet changed any of the transmit parameters for use with the IC-2GAT.

I think, but not sure, that a higher resistor may be needed since the
PTT is keyed "by providing a low impedance path from the mic input to
ground" (taken from the KPC-3 manual).

I am well aware of the fact that the TNC does contain an internal
isolation circuit.  However, since I wish to use this TNC with a number
of different radios, using this circuit is NOT desired.  It would
involve opening the TNC and resetting the jumper J2. While I am not
concerned with doing this, I think a much easier "work around" would be
to include a similiar type of circuit in the cable between the TNC and
the radio.

Those with an IC-2GAT, KPC-3 (or KPC-2) your help is appreicated.
Anyother help is also welcomed.

Thank you in advanced.

There is a list of the ip address coordinators kept on ftp.ucsd.edu in
the /hamradio directory.  The filename is called amprnets.  You can
get to it via an anonymous login.  It is a plain text file that lists
all the coordinators according to the geographic area they cover.  It
will only give you their name and callsign though, so you will have to
track them down some way to get into contact with them.  The best
thing to do IMHO is to find someone who is running tcpip on packet in
your area and ask them if they know how to get in touch with the ip
coordinator.  They can probably help since they had to get in touch
with the coordinator to get their ip address.  73 & GL

Hello,

I am looking for a possibility to use windows for workgroups 3.11 as a

an interrupt of my special I/O card and the activation of the

software.

The I/O-card is a Baycom USCC4 type in a PC slot which works well under DOS.
The windows packet radio program is WinPr. With this program the TxDelay
is greater than 50 ms and I can not use all digipeaters.

Does anyone has an idea to solve this problem? I tried it with a minimum

I'm not sure about the program, but a better choice might be a striped
down OS/2, in text mode OS/2 require less memory and runs very fast, and it
should not have any problem handling those stuff with 4MB ram.... Also
you can even multi-task in pure text mode (with out GUI loaded in memory).

   Well, the short answer is - it's impossible.  Primarily because
Win3.x doesn't permit pre-emptive multitasking.  Any process that is
currently executing can essentially grab 100% of the CPU time, until
it yields control back to Windows.  Now, working at the interrupt
level, you *can* grab the interrupt yourself, and allow the ISR to
do a bit of work, but you'll have to bypass the Windows serial
interrupt routines, which may or may not be an issue.

Uh, huh, Intel loves Bill Gates, but unfortunately throwing hardware
at the problem won't make it go away. The problem is that Win 3.11
is a non-pre-emptive multitasker. That's totally unsuitable when
realtime response is required because task switching only occurs
when the current app releases the machine, and that could be any
random amount of time.

Instead of throwing hardware at the problem, the correct response
is "get a real OS". MP/M on a 4 MHz Z80 could have done what he needs,
but Windoze on a 120 MHz Pentium can't. Switch to Linux, Solaris,
or even NT, but forget Win 3.11, it's brain dead.

There is a way of making data links at 10GHz, using gunnplexers. If I
recall right, there was an article of such in the ARRL handbook. I got
some gunnplexers and the range they are useful is huge! And combined
with a horn antenna or a 60cm dish, a link of several kilometres can be
archieved.

Here's how you do it:

1.      Configure a pc with MS-DOS 6.22 and JNOS 1.10m.
2.      Configure JNOS to use an Ethernet Packet Driver (Crynwr Packet Driver) and
        a serial port.
3.      Add the JNOS ethernet address to your DNS/Router
4.      Add the JNOS Ampr network to your router.
5.      Join a gateway group.

That's all there is...

Don't get roped into TNOS or Linux yet.  They're both not ready for prime time
.
TNOS is really just a BBS, Linux crashes with most 1.3x kernels using AX.25.

Yep, almost exactly the way I did it.  I use a jnos 1.10m compile that
just has smtp, domain server, ethernet, and PPP plus dialer in it.
Runs fine on a 286 with just 640k.  Acts as a store-and-forward for
incoming smtp email if the rest of the LAN is down, too.

I run another and much more capable jnos 1.10m on a 386dx-40 in one
Windows 3.1 dosbox (QEMM-8.01 for a memory manager) and FBB in
another.  Also have a G8BPQ Switch on the same machine, with both jnos
and FBB interfaced to it.  Although jnos and FBB could link to each
other via the FBB, I only move messages between them that way if
someone wants me to "convert" ax25bbs messages into smtp email and
vice versa.  For forwarding over Internet, I use a more efficient
method that involves the FBB Cron Server running a .BAT file that
attaches a smtp header to an FBB export, moves it over to the jnos
mqueue directory, and jnos then ships it off over Internet.  Incoming
Internet forwarding goes to the appropriate jnos Area, and the FBB
Cron Server "sees" the <Area>.TXT file pop into being, copies it over
to where FBB can import it and then deletes the jnos Area so that the
next incoming can be detected.  There's some carefull considerations
to avoid file-share errors, but that's the basic method I use to get
and send high volume bulletin (not much personal) ax25bbs traffic to
sysops who, like me, want everything but don't want to add to local
radio congestion or maybe they have really terrible netrom links.
It's all automated on my end, I don't usually have to lift a finger.

It was the need to lighten the 386 cpu load that had me move the modem
handling over to the 286 and ethernet the 286 to the 386.  FBB 5.15c
is rather cpu intensive during imports (not so bad on exports).  Not
only sped things up quite a bit on the 386, but also increased my
modem throughput.  Ethernet ftp throughput between the 2 jnos I
benchmarked at 84.45k bytes (not bits) per second, optimum, and smtp
between the two machines appears to be almost as fast.  I also gained
the ability to use a winsock on the 386 without having to take down
the jnos running on the 386 at the same time (but I do take down FBB
while running the winsock, because 5megs RAM just isn't enough).

It's a lot of fun, after it's all set up and there's nothing to do but
enjoy the rewards of all the previous work!    :)

You're almost surely correct about using Unix over other operating
systems, but I'd blame the operating system before blaming jnos for
stability problems.  Up to version 1.10m of jnos, I had stability
problems (memory leaks, mostly) but 1.10m has proven very stable for
me.  I tried the latest version of TNOS too, but didn't have to do
much beond running it to see that if it ever was serious competition
to jnos then it isn't so anymore ... used more memory to do much less.

I have a specialized jnos running on  640k 286 that just acts as the
modem controller, smtp store-and-forwward, a wanna-be domain server
(the domain server is stable but needs a full rework for reasons
having to do with features), and modem-to-ethernet bridge.  It also
has ftp, but that's just for remote sysop usage.  Works very well.

In a 386dx-33/40 5megRAM DOS-6.2/G8BPQ/QEMM-8.01/Windows-3.1 dosbox
environment, I run a jnos that does what the 286 one does, except it
does not use comm ports (the BPQ Switch does use comm ports).  It has
a full-service BBS, which I only use for mailing lists (like for
getting the nos-bbs techincal jnos email).  It has no converse, since
jnos is written to run in only within the 1st meg of RAM and one can
only support so many "features" before starving jnos for memory space
-- THE reason for jnos instability, in my opinion).  If I wanted
converse, I'd put another jnos box up for that purpose onto the LAN
(another 286 ought to handle it).

I also run FBB 5.15c in another dosbox on the 386, concurrent with
jnos.  This version of FBB is not nice with memory above 1meg and
tends to overstep its limits, causing problems with other apps that
also vary their usage of non-conventional memory space.  So I tend to
take FBB down (but not jnos) when I use winsock applications.

On both the 286 and the 386, having to reboot now and then is a fact
but not one I've been able to blame on jnos (anymore).  Operating
system (generally the memory manager) problems seem culprit now.  If I
just run jnos alone on the 286 and 386, I've no problems unless
there's a power outage or burp of some kind, it seems.  I've been
running jnos for around 5 years, and indeed it now seems stable unless
one starves it for memory -- if jnos gets below around 60k or so is
when I see things start to get shaky on my 2 systems that run it.

I find that jnos is a cost effective solution, especially if used on a
LAN, for accessing internet as well as amateur radio in all its
flavors, without having to learn Unix (one really has to be serious to
learn Unix!) and without having to give up a Windows environment.
It's stable enough for me that I move megs of amateur radio traffic
(primarily bulletins, I discourage personal mail) over Internet to
other hams who suffer from rotten radio links (and who don't have the
funds to upgrade the whole network to high speed for everyone, which
is most of us!) or who just wish to not congest radio space any more
than necessary to move a zillion SALE@ALLUS* bulletins every day.  <g>
FBB and JNOS do this 100% automatically for me, since they coexist on
the same computer.  I just let each do what it's best at doing ...

That's not really "baycom" and it's not really a "tnc":  What you
think is a tnc is actually just a simple modem;  the tnc action
actually takes place in the PC itself.  I like baycom and I have one
of the baypak modems and I think it works great and is a good buy for
the money.  But it is NOT a "miniature tnc".  This modem, in
conjunction with a PC running baycom or other tnc emulation software,
performs all the tnc functions.  The mfr. of the modem you refer to
probably is BayPak which is sold both directly and by Ramsey electronics
and probably others.
Advantages of baycom systems:
Low cost
Good Packet-only performance; often better than commercial tnc's
Reduced or no RFI to packet receiver as compared to commercial tnc's
Remote access to PC hard drive for email and binary file transfers
Small package size, nice for a portable laptop packet setup


Disadvantages:
No other modes with such systems such as CW, RTTY, FAX, etc.
Since the pc IS the major portion of the "TNC" you cannot disconnect the
PC from the  modem and let the modem store incoming messages as is
possible with most commercial tnc's
(see above) PC must be running in order for any packet functions to
work at all

Hi !

While we have no NDIS KISS driver, below the idea how to use ethrax25
driver with WIN95. I'am not sure that it's will work. Any comment ?

73! RX3DIN Victor
------------------------------------------------------------------------

With the ETHRAX25 driver, you can use  the ODI->Packet driver shim by
Don Provan @ Novell.

Maybe it let to us use Windows 95's NDIS/ODI shim to actually talk to
the driver...

                Ethernet Packet Driver MLID, v1.04
                        don provan 8/17/94

Introduction
------------

PDEther.Exe is an ODI to Packet Driver adaptor.  It provides an ODI
interface for an arbitrary Ethernet Packet Driver.  This allows ODI
access to any Ethernet board which has a Packet Driver and also
allows Packet Driver applications and ODI applications using
different network layer protocols to coexist in the same DOS system.


Using PDEther
-------------

In Packet Driver terms, PDEther is an application.  In ODI terms, it
is a LAN driver, also know as a "link driver" or "MLID".  The loading
sequence will be something like this:

1. Load the packet driver supporting your card.
2. Load LSL.
3. Load PDEther.
4. Load IPXODI, NetX, and/or other ODI applications.

Like all good ODI modules, PDEther reads Net.Cfg for configuration
information.  The next section of this document describes PDEther's
requirements for Net.Cfg, including a description of PDEther's Link
Driver section.

The first issue is that a dual bander usually can't switch bands under

No, a dual band radio won't interface with a GRAPES modem:  the GRAPES

plan:  with a transverter, the GRAPES unit will do 56K.

It appears that I am the victim of the usual Japanese to English translation
errors as well as my own memory failure.  I'll apologize for the confusion on
my part; Kenwood will have to come up with their own excuses.

My TS-440 manual very clearly states that the "FSK T" and "FSK R" lines appear

on two of the three RCA phono jacks on the rear heat sink (not in the 13-pin
connector like the TS-840).  When I continued to read the detailed explanation

in the text on page 18, these leads mysteriously migrate from FSK (digital)
into AFSK (analog audio).

However, nowhere does the manual say that you can or can't connect a true (TTL

or RS232) FSK interface to those jacks.  The front panel mode control switch o
n
my rig is labeled FSK, but that too is a lie from Kenwood.  Therefore you are
quite correct, there are no true digital FSK lines on the TS440, regardless of

what the official Kenwood owners manual says.

Pat,

All you need is a tnc, and radio, cable, and antenna.  I operate a
net/rom node that works exactly like yours, and it will do just fine.

You should look at how much traffic will be moving thru the node, and if
it is a lot, you might want to get the nodes on either side to backbone
with one hop at your site, then you move your local user port to another
freq other than the 2 other nodes.  That way, you can use it without a
bunch of collisions.  That is what I'm up against now, and working to
solve.

My gear is this:

PacComm Tiny II tnc- cost new $110 / used about $75 in good condn.

Kenwood TM 221- used cost around $200.

RG9913 coax. (Heliax would be better, but more $$$!)

High Gain omni antenna.

The eprom can be removed, and reprogrammed if you no of someone locally
with a burner.  If not, you can order one for $10 programmed up.  I
don't have an address of where to get that from, but if you go this
route let me know and I'll get that for you.

I use TheNet X1J softward in the eprom.  I find it to be much better
than TheNet Plus in my opinion.  It has many more features for the sysop
that can be changed remotely instead of reburning a prom.

Good luck!

Kenny

Yes, you've come to the right place. If you have to work over ordinary
VHF marine radios, there's a problem for speeds of 9600 baud and above.
That problem is that the radio must be modified. This may cause a legal
problem by voiding whatever is your equivalent of Type Acceptance. The
modifications are generally not technically difficult or extensive, but
they do require a small bit of skill to perform. A radio tech should be
employed. The legal hurdle is the big obstacle, you'll likely need permission
to perform the radio modifications, and you'll also likely need permission
to send the data modulation on the marine channels. Now for 1200 baud and
2400 baud, you can just connect to the microphone and speaker jacks of the
marine radios and go, no modifications are required.

For higher speeds, such as 19.2 kbaud or 38.4 kbaud or 56 kbaud, you need
more bandwidth than is available for a standard marine channel. At the
higher speeds, you also need a purpose built data radio and not just a
modified voice unit. These are available, and they aren't very expensive
for amateur use, but might be expensive if Type Acceptance were required.

For software, the best thing would be to use one of the TCP/IP packages
available for packet. They do internet style Email, internet style ftp
file transfers, and have telnet capability. They are fully interoperable
with the internet, so gatewaying would be automatic. Some of the NOS systems
also have a built in BBS if you really want to use that. I think that
approach is better than an old BBS and the antiquated YAPP protocol.

I'm not aware of any of the packet modems doing automatic speed switching
according to conditions. For HF and MF, packet, as currently done, isn't
a very good way to go anyway. You should consider using Clover II or Pactor II
instead. They are robust protocols for the HF and MF channel, and can
negotiate to suit conditions. There's a nice BBS system called Aplink
which you can use with them.

These systems could be used on VHF too, but they won't offer the speed
that VHF packet can give you, and channel conditions usually aren't so
bad that you need the additional robustness offered by Clover or Pactor.

> I also want to know the formula for calculating maximum speed due to band-

This is complicated. There are several modulation forms, such as FSK, MSK,
PSK, QPSK, M-ary SK, etc. And these may be double modulated, IE for packet
the usual method is AFSK over FM. That's a horrible bandwidth hog, but it
is simple and works for low speed packet data at VHF with voice radios.
The other methods are generally direct modulated. Each form has its own
occupied bandwidth equation. And then there is symbol overloading, which
can encode more than one bit per baud at the cost of needing a better
SNR. And there's the overhead of the protocol which has to be factored
in to get the effective data rate. It would take a book to detail all
the various factors which determine bandwidth for a certain data rate.
If you really want to know, I can recomend some books, or even post and
explain the formulas for some of the more popular modulations.

For ordinary 1200 and 2400 baud packet, that's about it. You have to
lengthen your TxD a bit to allow the repeater time to key up, but
otherwise you just treat it normally. Setting the repeater for zero
hang time can help if your users are using carrier squelch, but if
they are using data squelch, then you can play with the Axhang parameter
to speed up operation.

Now you can use a bit regenerator at the repeater. This doesn't really
help reliability much in practice, but it does keep voice users off the
repeater.

For 9600 baud and above, the situation gets more complicated. An
ordinary voice repeater won't pass those signals properly, and
will have to be modified. If you can get the received signal direct
from the discriminator, and feed that directly to the modulating
varactor of the transmitter (direct FM transmitter assumed), then
that can work. Everybody has to be careful with their deviation
and passband shape factors for it to work well, however. It might
be worthwhile to add a bit regenerator in this case to clean up
some of the nastier signals.

For higher speeds, you're going to be doing direct FSK, and a
bit regenerator will be needed.

Hi Greg,

Few things came into my mind..

The repeater should be able to open up without bleep/ctcss and send the id
as rarely as possible.  Modems should have carrier (packet-data) detection
so they know when there is data on air or is the repeater sending 'empty'
carrier. Txdelay has to be raised probably and the repeater is good to
adjust so that it doesn't send a beep at the end of turn. Someone else can
continue..

-- Packet should coexist on a voice repeater quite well as packet does
listen for activity (audio) before transmitting, something uncommon on
some voice frequencies. Parameters may have to be tweaked to compensate
for switching delays in the system. Sounds like a good combination that
may spark more packet interest your way.

That's what PL encoding (at the repeater Tx site) is for.  The repeater
transmits PL when it hears PL (voice) and transmits no PL when it hears
only carrier (packet.)  Then, voice users decode the PL on their receivers.

It works for me!

Hello all:

I am trying to put together a microcontroller application that will
involve controlling many small units from a single central control
station. The distances involved are in the hundreds of yards (although the
location--a city--is pretty radio-noisy), but the speeds I want are high.
Also, because there will be many of the receiving units, cost is an issue.

I do not have any real radio experience, and am just in the proposal stage
of this project. My questions are:

o Is there a radio protocol that already does what I want? Is it cheap?
What are the options?

o Is there a part of the spectrum that is available for applications like
this? Will there be FCC wrangling involved?

o Are there integrated solutions to the problem? Where can I look for
these?

Please copy any replies to me with e-mail, as I sometimes have a hard time

Absolutely... any machine running a xNOS can serve as a gateway router for
your station, as long as it supports a commomn LAN media with your
workstation (i.e. ethernet, SLIP. PLIP or whatever). I used to use a
macintosh running NET/Mac with two machines connected with LocalTalk. Now
though I swapped out the Mac router for Linux with TNOS (although you
could just use Linux if you have AX25 and KISS compiled in the kernel).

There is/was a driver for the Baycom that was written specifically for
Windows. I've ran it in Win 95 and it actually worked. I can't recall the
name of the author but I do remember he had a Web page in the UK. The
version I got from him was an alpha (or beta?) version for testing. He
thought he would release a final version after it was tested more. I run
packet from a 386 (with DOS) that doubles as a doorstop so never followed
up to see if a newer version was ever released. Since I've not seen more,
it might not have worked as well on other systems as it did mine, or the
guy found something else to do.

I was playing with writing a Baycom driver for Windows when I came across
one already written and so immediately lost interest. I did get far enough
to convince myself it could be done. I was also designing a standard serial
port converter for the Baycom but ended acquiring a glider (an
18 meter experimental class HP-14 :) ) and have been spending all my free
time trying to get it back to an airworthy condition. I know I could buy a
'real' TNC with a lot less effort and no more money than the Baycom, but
this is what I like to do. BTW, I even designed/etched the PCB I built my
modem on.

I'll tell you from many years of actual experience and setting up of many
gateways for myself and others that you shouldn't get roped into running
any DOS based version of NOS (such as JNOS) to run as a gateway if you
intend to run any kind of applications on it. If all you want is to just
run a router with NO BBS services, convers bridge, etc.... then a DOS
based system will work, but the moment you run a BBS or a convers server
will be the death of the gateway and the constant struggle to keep it
running. This is why I ported the IPIP daemon to Linux a while ago and
dumped JNOS. Gateways that run JNOS have a serious problem of crashing
constantly. There is NO reason for any BBS to ever have to shut down or
reboot at all, this includes housecleaning. By running some flavor of
Unix solves that problem and increases reliability big time. If you ever
notice which systems around the world are the main convers server hubs,
they are all Unix based. The next ones are usually TNOS for Linux because
of it's high reliabilty over JNOS or any other DOS based NOS (TNOS for DOS
isn't too good either, but the Linux version is stable).  On the 1.3.x
kernels, you have to find a good one.  I've run stable 1.3.x kernels and
have have zero failures, buggy versions though can cause problems. Just
ask which ones are good and stable and run that one (look at the patch
files, when you see a patch suddenly get very large you run the version
right before it, it's usually very stable).

I started out on a DOS based system several years ago, switching to a
Linux based router and server was the best thing I ever did, and everyone
else that has done so will agree with it. The only ones that won't agree
are the ones that have something wrong or did something wrong and can't
get it to work. The ones that work don't crash and usually have months
of uptime before they manually reboot it to change something.

If you want to use tcp/ip services over the internet, you should either

Compile a kernel with ax.25 enabled and use the appropriate
ax25-utils package.

or

Use one of the Linux tcp/ip software packages, such as TNOS or WAMPES.

Look at the gateway FAQ at minnie.cs.adfa.oz.au.

The baycom software is superior and if you register it, it is only
20 dollars. It allows full unattended binary and ascii file transfers
amd runs on old boat anchor type computers (like most of
us have). As many pointed out,  the software is very very
user friendly and beginners will be up and running in a matter
of minutes, and even doing multiconnects.

Note that baycom 1.6 software will run on a conventional tnc
in kiss mode, and since the tnc does the decoding, and
some slight buffering of data, baycom software will run under
windows!

Please note, there are many types of baycom modems. The
one everyone knows about is the Tigertronics unit. But, the
Paccom units are smaller, use less power and decode beter on RX.

73 and GL...Art...

I have used ver 1.6 on an old kpc-2 and a tnc2 clone.

The current (PALplus) move to 16:9 is clearly driven by manufacturers
who are faced with market saturation of TV sets, and need something new
to be able to sell...
With a 4:3 TV you will have black borders on top and bottom of picture
when a movie runs, with a 16:9 TV you have black borders left and right
for most everything else...  not much difference.

The 16:9 ratio also does NOT match movie aspect ratios, but you already
state that yourself.

It looks like there won't be much simulcasting here, but rather the
stations will first convert to digital and then to HDTV later.

As I said, the problem with TV is not with the hardware.

When you think packet is slow, consider upgrading your packet station
to be a bit more state-of-the-art.
Today, speeds of 9600 bps are common, and 56kbps is possible as well.

Using the Internet instead of a lousy packet link is like making a
phonecall to that rare DX country instead of working it on HF (or
via amateur satellite).

In theory it can be used, but practice is a different thing.
You will have to write a driver for it.  When you have no experience
with that, it is better to forget about it.
When you have experience with device driver writing, you could try
adapting the driver for an HAPN-1 card that also used the 8273.
One should be included in the different versions of NOS.
