Subject: FS: NORCAL 20M CW QRP RIG
This was one of the first batch. I built it with great care, and installed a
10-turn POT and did the suggested mods, and tuned it to "prefection"
with an 0-scope. Excellent QRP rig, worth its weight in gold. Unfortunately,
I just don't have the time for radio these days, and I need to pass this
baby on to someone who can enjoy it and get some use out of it.
I am asking the same price I paid for it, because it's worth it, and it's
in good shape. PRICE: $120.00 + $5.00 priority mail shipping.
Email me if interested. Prepayment with M.O. or check preferred.

Yes, I suppose you could write such a program if you really
wanted to make life difficult for yourself. Do you have an
example of such a program?

Difficult? Not at all. I've an X11 program (that I grew bored
with so never finished) that implements AX.25 in userland and uses
a TNC in KISS mode to get the bits in and out to the box. Why?
Because the world isn't Linux and my *BSD boxen don't have kernel
mode AX.25. APRS was the second thing I implemented (receive only)
as there are no states to worry about. The first thing was the
equivalent of an AX.25 packet analyzer.
Someday I may finish it. But if I do I'll use soundcard DSP instead
of a TNC as that way I'll be able to add psk31, too.

Since this thread is about APRS under Linux, I wasn't worrying
about other OSs. In this thread the world *is* Linux, and any
Linux network program that didn't use kernel mode AX.25 would
have to have an awfully good reason not to.
I'm still waiting for an example...

Most Windows programs are like that. I use this method to run UIview in a
Windows95 VM under VMware.
It isn't really difficult.

It also serves the unique addressing of amateur radio stations, and
division into subnets. When you want to route along some nodes in the
amateur network (when available locally), you will probably need a 44
address, as all the routes in the routing tables are geared towards the
subnets on that network.
(i.e. in most nodes there will be no route for net 10 or it will point to a
default interface)
