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

[Hasan al-Basri]

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
