Requires a scanner with outside antenna
and soundcard for the PC
and a high resolution truecolor video card
- Mir over Traverse Bay, Northern Michigan
- Mir over somewhere in lake Superior/Winnipeg area
- Mir over twilight area NE US, SE Can
- Mir showing earth curvature
The frequency of the signal is
145.985 +/- about 3 KHz for doppler.
If you use a ham radio type receiver, it is
best to try to follow the doppler, but most
scanners are a bit wider in bandwidth and even
with the doppler the signal stays in the bandwidth pretty well.
The program I used was ChromPix

although there are a bunch of other similar programs

Normally Mir is in a packet mode, and occasionally you can hear voice, but for the last couple
months they have had the SSTV on the weekends
and usually forget to switch back until Mon or Tue.
The SSTV is a wobbling 2-tone signal that lasts about 15 seconds,
and they send it about every 2-3 minutes.
