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 :-)

Tnx W9KE Tom Doyle
I will not suggest that you move. But did you check the restrictions before moving there? Seems a no brainier for any ham.

John,
Thanks so much for that answer. It was a big help.

it was not a "answer" but rather a "question." Plain and very simple.

The signal in that graphic seems strong enough to decode.
The best way to use HDSDR or any SDR program with the FUNcube Dashboard is with a Virtual Audio Cable driver like this ( http://vb-audio.pagesperso-orange.fr/Cable/). Then you set your SDR software audio output to the VB-Cable Input (which looks like an additional sound card on your system) and set the FUNcube Dashboard soundcard input to VB-Cable Output.
I also decode and upload telemetry by recording audio of passes with my FT-817 onto an audio recorder and using VLC Player to output the audio to the VB Cable. I decoded and uploaded 60 frames from half a pass of FUNcube-2 on UKube-1 last night that way.

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 Tom -- just checking real quick, from your pic, it shows that the actual data stream from the sat is being picked up in the FCD dashboard, but the signals are right up against the zero line on the left, and looks like some of the signal might have been clipped off to the left. To confirm, you also tried with the main signal somewhere in the middle of the FCD Dashboard's "passband"?
(sorry, I run my FCDPP direct to the FCD Dashboard, so I'm just used to seeing the sat signal display around 55,000 on a scale of 0-96,000 Hz, so not entirely familiar with running the sigs through HDSDR recording first)
