Hi Jerry,
Is there anything between the speaker out and line in (or mic) on the sound card?
What are you using for radio/Doppler control?

The orange indicator is following something, usually hanging around the middle of the orange line range when there is a signal. Any thoughts? Windows Vista SP2 with M-Audio Delta44 sound card set for 48000Hz sample rate.
Thanks! Jerry N0JY
Make sure your receiver has any noise filters turned off. They can prevent the decoder sw from working.

I was also having trouble getting telemetry. Signal was quite strong and all indicators was within range. The telemetry and CW stopped twice within pass. CW was decoded but maybe the deep QSB made some impact to the telemetry. I have 2x 17 el horizontal yagis, FT-847 and Realtek AC97 audio system. Sampe rate was 44.1 kHz. Next time I try Edirol UA-1 USB sound card. Have to set alarm clock at 4 am local time as this is the only time ISS is well above horizon... :-)
And please try the ARISSatTLM software and decode some frames as it is no help if you just say you can hear some noise...

Hi Mark,
I'm using the speaker output so it's speaker audio with no additional filters, right to the Delta44 breakout box. SatPC32 does the doppler, it's set for 20Hz interval. Should I set that lower, to 10Hz perhaps? I am going to try to use the audio from the data output on the FT-736R. A brain fade on my part prevented me from getting the signal off the ring of the stereo connection, but I just woke up and remembered that I have the splitters for that so I've got that connected to the breakout box now!
73, Jerry
