[amsat-bb] Foxtelem and Kenwood TM-V71 signal to noise ratio

[John Brier]

I made a cable to tap the 9600 data pin off my Kenwood and I'm trying
to decode telemetry from AO-91.

I am having trouble getting a continuously clean reception, so I don't
expect frames, which I'm not getting, but parts of the reception are
fine and yet FoxTelem still shows a low S/R of 1.2, 1.5 at best. I am
wondering if there is still some filtering going on. I notice the
peaks of the "bits" are not flat like they are supposed to be
according to the manual:

I am recording the audio off the radio into a Zoom H1 at 48,000 KHz 16bit wav.

Maybe I should try hooking the radio directly up to a computer into FoxTelem.

Here is my recording:

Ideas?
