Once again! DSL reaches ORBIT ! The ISS has been invaded by DSL !!!
Here's the stuff,
At about 07:19 CST, another fine pass over North America..
Saw quite a bit of traffic.. Even got in a few G'Mornings to some folks..
I added the APRS position string to my unproto path, and now
you can see the traffic from my station at the NASA web site -
< http://www.ariss.net >
Here is a copy of the log, and the save from the ariss.net website for the details,
as the ariss.net site is always updating from new passes.

Do you want details on Amateur Radio in general, or , specifics on how I "worked" the ISS with DamnSmallLinux ?

Here's a brief...I use a Terminal Node Controller , or "TNC" for short.
It's basically a "radio modem" ,
and looks very similar to a typical external modem.
Here are two different models I have.
The smaller one gets its power directly from the com port.
This connects up to a serial port on the back of the computer.
Another cable connects the TNC to a transceiver, in this case,
a Radio Shack HTX-202 2-Meter ( 144 MHz - 148MHz ) radio.
It's set to 144.390 MHz , the National APRS frequency.
It is connected to the microphone and earphone jacks.
The FAT cable you see exiting the top of the radio runs out
to a 13 element antenna, designed for the 144-148 / 2 Meter Band.
It spins around with a "TV" rotator, so I can track the passing
of the ISS from horizon to horizon. I monitor the path of the
ISS with the predict / GSat server and GUI.
Xastir 1.4.0 communicates with the TNC, just like and old style
X-Modem or Procomm program would with a typical modem.
The TNC creates the "packets" of data that are sent in an
audio stream ( remember how 300 baud sounded? ) to the
transceiver, and broadcasted out to the airwaves.
Next post, I'll walk thru the xastir setup..
