To: ham-digital@ucsd.edu
*** This message pertains to operators of packet to internet gateway ***
*** systems. ***
There is a message currently circulating to all such systems from
Bill Healy (N8KHN) relating to this. Mr. Healy was operating our local
packet gateway in Reno Nevada, when it was wrongly put under the
university ham club's control. I am the chairman of the university ham
club.
Through repeated misunderstandings and problems not directly
related to the Hamgate system, Mr. Healy's system was shut down by the
ham club last week.
I wish to apologize for any problems this may have caused you.
The university is currently working on a solution to this problem, and
will have another system up shortly.
I will not be writing any follow-ups to this post, as I do not
read this newsgroup. As I am considering this matter closed, replies to
me may be returned unanswered.

Brian,
I appreciated your msg., as I have been working steadily over the past
13 months to get 9600 packet working for one of our LAN groups here in
Atlanta, the East Atlanta LAN. It's tough, really tough. I'm presently
experienced with the MFJ1270 and their kit, a G3RUH actually made by
Paccomm, and a TAPR 9600 kit, which I installed in my PK232MBX. Each has
some uniquely good and bad qualities. I can't really say that sloppy DCD
performance has been at the core of it; or at least at my experience
level I don't think it has.
-> work very well. Those circuits chatter; they occasionally false on
-> background noise, and can be fooled by interference of various kinds.
I haven't seen either the G3RUH or the TAPR modem false indicate DCD,
even once. I've seen it not pick up valid data (or so it looked to me)
but not false.
I've been trying to work simplex right now; we don't have a full duplex
repeater up yet; so we're limited to that. Also, I'm experimenting with
half-duplex without a repeater.
I'm at the state where I can get each system to regularly decode
another's beacon text, I can connect dependably (with an average of 1-2
retries) yet when I use mailbox features to simulate more robust
traffic, often I get into retry hell. How can that be? How can I read a
beacon great, connect great, just not put any meaningful amount of data
through? Any ideas?

We're getting the cart before the horse in this message thread. 9600
packet is an IF interface; squelch control is a AF section function. The
audio at the IF is always unsquelched, and rightly so. Further,
<anything> do to with the AF section screws 9600 transmissions up due to
the normal pre-emphasis and de-emphasis curcuitry in the AF section. It
seems that 9600 packet audio requires it's own custom de-emphasis based
on the exact discriminator used in order to get the eye pattern right to
the modem. Hence the difficulty of getting the IF interface right.
So...bottom line is...doesn't matter how fast/slow the squelch
is...you're way on the IF side of the squelch curcuit anyway.
I clearly state here that this is an area for ongoing discussions, as I
am not satisfied with the work I've done so far in 9600 packet, so any
help/comments/objections is appreciated.

Daniel,
I caught your broadcast response offering info. on above subject.
I'm looking for interface info on adapting the Mitrek and Micor radios
to 9600 baud use. Specifically, the modem interface and full duplex
modifications.
I would appreciate you forwarding any info you have. I am forming a
conference and file area on my ham radio BBS dedicated to 9600 packet.
Perhaps, this will make it easier for hams to complete the interface in
the future.

A "typical" modem cable will not work correctly with HostMaster for the
Macintosh. Most "High Speed" modem cables will work ok. Kantronics
Host Mode uses hardware handshaking.
I've used a Radio Shack RS232 Jumper Box to convert Apple 1200 baud
modem cables to work with HostMaster. I can give you the wiring
diagram if you need it.
BTW, I wrote (and support) HostMaster for the Macintosh for Kantronics.

Subject: ▄SUMMARY| PK-232MBX vs. MFJ-1278B
To: ham-digital@ucsd.edu
I got a lot of helpful replies to my recent "PK-232MBX vs. MFJ-1278B"
post. Thanks much! Here's what I learned:
Most people strongly prefer AEA's gear over MFJ. Apparently, MFJ's
quality control leaves something to be desired. Some have had better
luck than others, but some replies indicate that MFJ does much poorer
with weak signal HF, and the MFJ leaks significant amounts of RF,
which hurts some more than others. The filtering on the PK-232 is
much better than the MFJ's, and the tuning indicator is more useful.
Both units are about equal for local VHF packet, where filtering and
discrimination isn't too much of an issue. Many recommended checking
into the KAM units or PK900 as well, but I haven't yet.
ROM upgrades for the PK-232 are more expensive ($75 + $25 for docs)
than the MFJ upgrades ($25). If you plan on upgrading often, this may
be an issue.
It's true that only the MFJ does SSTV and shaded Fax, so for those who
use it for that, the AEA can't substitute. However, most replies
recommended getting a basic Fax-only box if Fax is going to be a
significant factor. The AEA-FAX (~$100 hardware & software) is well
recommended.
Apparently, AEA doesn't provide or make available any software to
decode the Fax data from the PK-232, making it pretty useless. MFJ is
a better about it, but doesn't get along with Windows very well. The
MFJ software may also be minimally copy-protected, which seems odd.
The internal BBS feature on the MFJ (pbbs) seems a bit better than the
PK-232's (PakMail). People like the CHAT command and some
auto-forwarding features. It sounds like gobs of RAM aren't really an
issue for personal mailboxes with medium traffic.
Overall, it sounds like the PK-232 is a much more reliable unit for
Packet and other modes, but if SSTV or Fax are critical, MFJ or
specialized boxes are the only option. Many suggested starting with
the inexpensive Baycom (~$50), but it only work's on DOS machines.

There are two programs that I know will work... One is TOR... I don't
remember the version... I think the last was TOR30x.ZIP... This was
shareware... I also forgot the author...
The software that I use is BMK-MULTY... I am using a HAL CRI-200 modem...
BMK-MULTY, written by G4BMK, is the ultimate RTTY/AMTOR/PacTOR/CW software
for dumb modems... While the initial cost is high, and the software is not
resaleable, because it is encoded with your callsign, it allows the use of
simple, good and affordable old-style HF modems... Upgrading your modem is
then relatively easy...
Check the back of QST for info on BMK-MULTY...

I HAVE BEEN RUNNING BAYCOM SOFTWARE FOR AWHILE NOW AND I LOVE IT.
I HAVE ADDED THE YAPP DRIVER AS WELL AS A 7PLUS ENCODER/DECODER.
YOU WILL NEED A BAYCOM MODEM TO CONNECT THIS TO YOUR RIG.
I RUN ONE THAT IS A KIT FROM A&A ENGINEERING.
THE BP-1 FROM TIGERTRONICS WORKS NOT TOO BAD EITHER BUT IT DRAWS IT'S
POWER FROM YOUR RS-232 PORT SO I PREFER THE A&A UNIT AS IT HAS IT'S OWN
POWER SUPPLY.IF YOU ARE INTERESTED IN MY MODIFIED VERSION OF BAYCOM,
JUST DROP ME A LINE AND I WILL SEE WHAT WE CAN DO.

I found the same thing when I examined the docs as well. It appears that
there must be some provision for sound boards as you have the ability to
direct the output of the program to the speaker, serial port, parallel port,
or serial device.
A friend of mine uses the logitec borard and has no problem in getting the
program to run on that board. The problem appears to be the Sound blaster

Hello,
I see there's no NETROM facilities into the TNOS compiled distribution.
I have some difficults to recompile the TNOS with BC 3.1.
I ask if someone includes the NETROM facilities into the TNOS and if
it's possible to send me the exe.
I test the TNOS on a 286 and sometimes the system hanged and stop.
I assume it's probably due to a lack of memory (only 2048 K) because
the
system stop when there are some connected features and only 12000 Bytes
free.
Could you help me to boost the memory process.
Many thanks.

Unfortunatly, I don't see any groups or like that when I connect the

to have a NEWS center with more than two choices. I give the names for
these facilities. But I only have two choices.
Into the directory NEWS or NNEWS, some files must be configured I
suppose.
Into the directories INFO and TUTOR it's probably the same.
Could someone help me to find the proper configurations to have
NEWSgroups.
Could someone help me to find or send me configurations files samples.
Best regards and many thanks.
