think they stock them anymore.
Hopefully some one will tell you that this is all antique, and there is a
better way now.

Subject: Need help wiring Icom 2GAT HT -> MFJ TNC
Greetings-
I have an Icom 2GAT Handheld that I want to get working with my MFJ
1276 TNC. Being the DIY type I tried to amake the cable myself according
to the instructions in the book but the directions aren't clear about
whether my HT is one of the ones with oddball keying. (It receives OK
and keys the transmitter but it only sends an empty carrier when it keys
up).
I anyone knows where I can find a good DIN-plug to HT-connection
diagram please let me know, as well as any "gotchas" to keep an eye out
for in the process.
Please reply via email.
Thanks in advance for any help you can give!

Subject: NOVICE: replacing line modems with packet radio technology?
Hello all. Sorry if this is the wrong place to ask the question, but what
is the possibility of packet radio being used as an alternative for line
modems. Let me explain:
I've read a few papers and intro. articles on packet radio and how it can do
tcp/ip. There doesn't seem to be a lot of information on how many people
are regularly using this to get on the internet. I couldn't find much
information on how the costs compare to line modem ISPs and didn't see much
about the distances/line of site requirements.
It costs about $15 to $20 a month to get internet connection, so perhaps
that's why packet radio hasn't proliferated. However, in parts of the world
getting internet connection through standard telecommunication media is
extremely expensive (if short phone calls are expensive, an hour on internet
per day can add up).
If someone wants to set up an ISP (perhaps city wide, for a fairly
large/congested city) using radio instead of phone/xDSL/cable/etc., what
issues need to be addressed. What are the limitations. For example, it
seems like someone using this radio technology will be able to have a 24
hour connection, albeit a slower one. However, that should be fine for an
average middle class home outside of the rich/developed countries who
basically needs email and maybe a little web access.
Such access in city might be fine since all nodes will be geographically
close (let's say a city size of Chicago...possible?). What about if one
wants to link rural villages in remote parts of the country.
I'm not concerned about laws or regulations at this point. Just wondering
it will take to do such as thing. There seems to be a lot of information
about packet radio directed at old amateur radio operators, but little
towards people who want this to be what I explained above.
Another concern is cost. Apparently there are products sold by lucent, etc.
(although I know VERY little about them), but they seem to cost hundreds of
thousands of dollars....not a good alternative to phone modems used by
residential users.
To give you a better idea of where I am coming from: I am vaguely familiar
with amateur radio (had a few friends who used to talk about it all the
time). My background is computer science (currently an undergrad, senior)
not don't know that much about circuit design and specific details of
different protocols.
I'll GREATLY appreciate it if you could CC a copy of your reply to
chaudhar@umic.edu . Thank you in advance.
Waiting eagerly for your response,
Shahbaz C.
