Tom,
I recall in conversation with one of our Fox Team who was using an SDR
application that MIGHT have been HDSDR, that the I-Q can be inverted. I
don't know if it's a setting or what, I don't use HDSDR software and as
I said I'm not sure he was using HDSDR. But it might be worth a look to
see if you have such an option and switch it to see what happens.

Hi,
Recorded an AO-73 telemetry pass (RF recording) this morning with HDSDR.
Later fed it from HDSDR into the sound card and then to the FCD Dashboard
(see pic). It appears the signal is making it to the Dashboard but nothing
seems to happen. I tired (Auto Tune) on/off, and narrowing the bandwidth of
the HDSDR filter to better match the bw of the signal but still nothing. It
does seem to lock on to the (Detected Frequency 2262 Hz) but that's about
all it does. The Dashboard is brilliant and I would like to get it working.
Due to deed restrictions no outside antennas are allowed so the signal is
not that strong here (about 5dB above the noise) and it might never work
from here. Any suggestions will be appreciated. Any suggestions that we
move to a new neighborhood that allows outside antennas will be forwarded
to my wife :-)
