[amsat-bb] FoxTelemetry on AO-91 and AO-92

Several of us are having a heck of a time getting any telemetry from the above birds. DUV just isn't producing anything.

We hear both well enough to make QSOs on the FM transponders, but we can't seem to get any data thru the decoder.

Is it really that much more difficult to get the TLM via DUV than to listen to a voice on the 2m downlink?

Setup: 2m Eggbeater at 7', fed with 80' of 9913 AirSpy HF+ SDR SDRC V3 Software FMN 12 kHz (Highpass Filter not checked) and FMW both tried, neither produce any decoded data.

I am getting telemetry just fine from AO-73, and am also getting perfect Wx pix on 137.100 with SNR's of > 30 dB.

Am I doing something wrong, or is it just that hard to get FoxTelem to work with DUV?

Thanks for any help. 73, N0AN Hasan
