daryll -

i'm new to packet and i am using a baycom. i bought the software and modem
for $50, more or less. yes, you need a modem to interface your radio to
the computer. the circuit of baycom's modem is available (i think) on some
boards or you will find adds for baycom in qst.

it seems to work fine, at least for the stuff i use it for. it seems a
cheap intro to packet.

To: [e-mail]

I'm going to be connecting a PacComm Micropower-2 TNC to my Realistic HTX-202
as soon as I get a cable cobbled together.  Does anybody know about what a
good volume level for the '202 is in this configuration?

Also, what's the TX Delay for the '202.  The manual doesn't seem to be of
any help, unfortunately (which is too bad, considering that for the HTX-100
they mention what the TX delay is).

Tnx in advance,

Doug N0YVW

Mike,
     No, you can't put the ICOM 12 volt pack on the HTX-404.  It would
probably work for a while but it would cause serious overheating of
a regulator that was designed to work with the stock battery pack.
Yes, you are right, it is a serious booboo.  By the way, it is not
an ICOM rig, it is Midland.  Unless of course, ICOM makes it for Midland
who then puts Radio Shack on the label.

I have the SCS Pactor spec; there is no spec on block repeat time for
Pactor FEC.  The two units that I have tested (PK232 and SCS) both repeat
the FEC block with a 1 sec period.  However, in talking the SCS people
at Dayton, their intent was to use a correct CRC as the sync indicator
rather than locking to a particular transmit time, as you do in an ARQ
link.  With the frame header character that they have selected, it makes
it real hard to sync on the front end of the block.

James,

  I don't know much more than a tame crow, but...

  Well, I'm about to do the same thing myself, so maybe we can help each
other.  The reason that there is no information provided is probably because
it depends upon the EPROM burner that you are using.  The one I use simply
takes an image file and burns it into the EPROM.  First, however, I think you
have to use the editor to set those parameters which go in the EPROM.  I just
got X-1J R2, and haven't looked at the tools (if any) which come with it.

  Maybe someone who knows something will join in here.

Subject: 9600 bps radio modems
To: [e-mail]

I'm disgusted with the performance of the carrier detect circuits in
the three popular 9600 bps radio modems used by amateurs - the K9NG,
G3RUH, and new TAPR modems.

None of these has a good carrier detect circuit.  All three use a DPLL
to discover that there's a data carrier out there, which doesn't really
work very well.  Those circuits chatter; they occasionally false on
background noise, and can be fooled by interference of various kinds.

The K9NG design doesn't do much about that; its DCD output just
chatters.  If you use it to gate data to the USART in the attached TNC
or PAD, you lose perfectly good packets because the DCD chattered off
in the middle of a packet.  If you use it to key your repeater TX, the
radio will thrash all the time because of the false DCD indications.

Sure, in the G3RUH and TAPR modems, additional circuitry has been added
to prevent the thrashing, and the output of the DPLL is "smoothed" to
eliminate most of the chatter, but there is still one big remaining
problem:

They're SLOW!

These things are taking between 50 and 100 msec to indicate an incoming
carrier.  That's longer than some of the packets.  Waste of bandwidth.

I'd really like to come up with some sort of better DCD - and it
wouldn't hurt if it had better data recovery performance as well.

Sure, the right answer is DSP.  N4HY will tell you that, and I agree.
But short of that, is there some approach that'll help?

(Being compatable with the scrambled direct FSK that the current modems
use would be a plus, but isn't required.)

I'm the author of KAMterm.  KAMterm is a (currently only dos-based)
terminal program for Kantronics TNCs that takes advantage of the Kantronics
host mode terminal interface.  This mode basically allows you to do a lot
of things that you can't do in the normal dumb-terminal mode.

If you'd like more information about it, please feel free to e-mail me (be
sure to put ``KAMterm'' in the subject line---I'm ***WAY*** behind on
e-mail, but KAMterm mail always gets my fastest possible response, i.e.,
it's usually only delayed by UUCP delays...and nothing else).

I just bought a HTX-404 from er, ah.. Radio Shack, and knowing that they are
made by ICOM and noticing that the battery pack looks the same,
I asked the GBTC (Guy Behind the Counter) about whether I could use
my ICOM battery packs on it. He said no, that if you use a higher voltage
battery pack (for instance a 12 volt one) it "would burn out a little diode
inside the radio"..

   Anybody know whether this is true? If so, it seems like a collosal
design blunder, especially seeing as how there is no warning in the
user's manual  telling you not to do this!

Not installed v2 anywhere yet - I have the stuff but I haven't been to
any of our remote sites for some time. Currently our local network is a
mix of X1G, X1H and X1J and BPQ nodes, and while they work I tend to
leave them alone (one site has kept its TNCs running for over 10,000
hours without a crash or power fail). I will get round to updating to
X1J v2 sometime though :-)

reply to who ever it was.....

---------------
James is quite correct when he notes that all programmers are different.
It is exactly for that reason that no guidance is offered.  There are
however the following:

    A utility to convert the ROM images to INTEL hex (source + exe)
    A utility to convert the ROM images to Motorola S  (ditto)
    A patch utility that is used to customise the ROM image, with
      on line help and ability to save/load standard settings.
    A configuration guide for manual patching if you must do so
    A couple of examples of how to use the tools.
