SEEDS spectrogram

Last night I was redoing my Python script that did Doppler tracking. There was a very low (max elevation under fifteen degrees) pass of SEEDS II that came up while I was making changes, so I went ahead and used it to record some of its Morse telemetry. The signal was pretty weak and intermittent, but I was able to hear it pretty well. I keep hoping that I’ll catch it in SSTV/Digitalker mode, but so far, no dice. I did make a spectrogram of the pass, just to see that morse telemetry. Click the link below to get the (very wide) picture of the telemetry.

Morse Telemetry from SEEDS II

The signal was pretty weak and hard to hear, since I was recording it on a low pass, and from within my house to boot. Here’s the audio:
