I'm new to the group so I apologize if this has already been done to death.
I've been a HAM for about five years, though I've been limiting myself
to 2m (can't run HF in my building... bad grounds... and it's explicit in
the lease...).
I travel a lot and am interested into starting packet. I've just seen
a nice little BayCom TNC the size of a DB25 shell. Sorry, I don't know
the model... It would be great on the road with my laptop and Kenwood
TH-225A. I'm not really interested in mailboxes or the like, just a
straight TNC. Maybe I'll eventually want more, but not now...
Anyone have anything to say about the thing? Both good or bad accepted.
E-mail or post, thanks...

The Tigertronics BayPac is the modem I think you are referring to and I
had one. It is a nice, simple, useful little gadget. However, I said I
*had* one. I owned a Zenith laptop computer at the time I got it and it
worked great from the parallel port of this computer. About a week after
I got the BayPac, I got a new notebook computer for my work and had to
send the Zenith back to the lease people. I found that the low power
consumption features in the notebook were not sufficient to drive the
BayPac. In the manual it showed that the modem required something like
10v and I was only getting 8.5 to 9v from the port. It wouldn't run at
all. As I said, on the other laptop, or on a friend's desktop, it ran
perfectly. I called Tigertronics and they couldn't help me. I had some
local HAMs look at it but to no avail. I ended up selling it and, to my
knowledge, it is still in operation here in the area. To make a long
story longer, the moral of the tale is "Check the voltage from your
parallel port!" and make sure it's 10v or more. I wanted it for portable
use myself. It would be a great setup.

Hello folks. I built the Baycom Modem and I can run it on any laptop without
any problem. It's different from BayPac. This Baycom modem is using the
famous TCM3105 chip. It can be used to run the Baycom and TPK softwares.
I can send you the circuit diagram (GIF file in UUENCODED format) if you're
interested to build...it's very simple and very cheap to build.

For those of us new to packet what is wrong with these tnc's?

Nothing. The only thing about them is that they are pc TNC emulators, not
real TNCs with internal processors so you have to leave your pc on when
you want to monitor or use the station. The stand-alone TNCs can do just
that, stand alone and monitor traffic or receive mail without the pc. The
BayPac is just a modem and all the work is done by the pc. I must admit,
I started the same way as the other guy. I built a PMP machine and had a
blast with it. Before too long, I had a PK-232 on order. I wanted the
multimode ability. I still have the PMP. Anyone who is not sure if they
will like packet should maybe go with this type of set up. If you don't
like it, you aren't out a lot of money. If you do, you can keep this one
or upgrade to a more featured TNC and can pass the BayPAc on to a local
who is in the same boat you got out of. The choice is always yours.

I'm using a baycom style modem (not the Tiger... BayPac) on my home PC, and
of course, it works with suffient power. But according to the docs on my
construction, in the event of 'insuffient power', I'm allowed to try tap a
external 10-12V in from an additional pin I have.
Perhaps you could try find if there is a way to attach an external battery
to the modem - just don't fry your laptop in the process. 8)
Rgds!
It's *not* a TNC. The TNC functions are provided by software on the
PC. The Baycom unit is simply a modem. Mine works fine, although I
prefer my "proper" TNC.

I understand why you had trouble with the BayPac... It runs off the serial
port, not the parallel port... If you were able to plug it into the
parallel port, which you can't, it would never work... Hope you didn't buy
an adapter for the parallel port and try and run it that way...
If you did plug it into the serial port and it didn't work, it may have
been because the serial port wasn't turned on... Some serial ports are not
turned on in normal operation in laptops... There is usually a command to
turn on the port in the specialized operating programs for the laptop...
I had a BayPac for years and it worked on every laptop... I now have a
PacComm because almost all laptops have DB-9 connectors for the serial port
and PacComm sells a BayCom modem in a DB-9 shell... VERY small...!!!

Hi,
Can someone mail me the gif file that has the circuit diagram on
how to build this?
Also, if anyone can point me to some small source code that runs
a protocol (xmodem, kermit, anything really simple and tight) I would
appreciate it. I'd like to be able to build two of these modems and
experiment with sending files back and forth. AX.25 is too big for the
micro-controller I have.
Thanks in advance,
Raj
I found that it was already posted. Thanks!

This request still active! :-)
that the buyer will invariably upgrade says something right there. where
the problem is is misrepresenting a modem as equivalent to the classic
TAPR TNC-2. If you already have a computer to spare for the job, great.
but if you want to run in some other environment than plain old dos,
things become much more diffcult.
obviously a full up multimode controller may exceed the budget of
someone just wanting to get on packet. i think the baycom type solution
is interesting, but isn't for situations where multiple people have to
use the same equipment...for a while, we actually had a situation
where equipment type didn't matter -- what you learned using a PK-80
applied to other manufacturer's products.
now you get guys that think you have to have a special program to do
anything on packet (and the software guys have to answer for that...)
especially for those programs that leave the TNC in a "hard to talk
to" state...(a friend has a PK900 that has to have it's mate program
running to convert what used to be MYCALL WB9IVR into whatever
cryptic string it wants...when his computer was kaput for a week,
he was kaput, even tho he had other equipment that could talk RS-232.
all because somewhere along the line, someone decided that window
dressing was no longer optional.
(aside -- it's quite possible the PK-900 can talk in english as a
TNC 2 could. I've never found where you set this up in the book tho.)
that's probably why i don't do much in packet these days...when it
lost the universialty the "dumb terminal" interface had and didn't
pickup anything useful in exchange, i figured i didn't want to get
into the study of the Mysteries of the Shift-F8 key for the program
of the week.

Pardon me for jumping in here but.....I wanted to give packet a try
without spending a lot of money. So, I bought a Baycom. It does a fantastic
job for what I want. It works great with my laptop and my XT. I especially
like the 3 window split screen. Other packet users that have seem my demo
at club meetings also seemed impressed. I bought a Kantronics KPC-3 to use
on a gateway to Internet. I tried it at home with the crummy software that
came with it. Personally, I prefer the Baycom. Sure, it doesn't have
mailbox or BBS capability, but, so what? I don't need that ALL the time!
I've made contacts all over the world with my Baycom and Icom 2AT. It's
a lot of fun dropping into a qso halfway around the world with my indoor
2 meter antenna and $50 "TNC".
Have fun, and 73 de "A.C.", W5EZM in Houston, Texas
