I was wondering if anyone has tried to record a .WAV file of this bird & decode it later on. I've seen some archived posts where MixW was used, but it wasn't clear what the individual did to set up the software. I've tried tinkering around myself with MixW - I played the file back & ran a cable from the speaker out to the line in on my computer, but I don't think I had the 9K6 protocol set properly in the program (basic changing of the parameters didn't work either).
I guess I'm looking to "cheat" from you guys since I can't get any decodes. Is what I'm trying to do even possible?
For a little info on my station setup:
FT-847 audio is captured from the DATA port for 9K6 & higher speeds auto track for antennas & doppler Audio recording in 8khz mono (could there be a problem here???)
Yes. For 9K6 (9600 baud data) you should recover audio from the 9600 line (pin-4 on the Packet Jack). Did you misspeak when you said "DATA". On the FT-847, there is a separate DATA jack that provides for audio output/PTT and audio input for psk modulation/demodulation.
Likewise your recording speed should match or exceed 9600 Hz (others correct me if this bad advice).
PS: I used MIX-W2 for recovering telemetry from AO-40 (but I am far from an expert on using MIX-W).
...I receive GO-32 quite well with an S-5 or better on some passes, so receiving the signal is not an issue. Even if it's just sending telemetry right now, it would be fun to play with the high-speed data. Is there another program I could use for decoding the data? Any help is appreciated! 73's from FN41
Have you checked the Amsat-NA website? It has been some time since I captured telemetry so maybe someone else could help with GO-32 data
