My Fox Telemetry program is not decoding AO-85 anymore. I'm looking for
suggestions on where to start looking for a fix. 

In the past it would sometimes stop working. At those times, I would
Uninstall, then Install a freshly downloaded version, and that seemed to
work fine. It would always work up until I get to around 100 data
packets downloaded, then it would quit, so I would uninstall, then
reinstall and I'm back in business. 

This last time, the new Install is not decoding, even on beautiful "eye
forms" with SNR >4 and 5. Very frustrating. 

I know I'm not doing something right as I assume I shouldn't have to
reinstall after every 100 or so downloads and I definitely did something
wrong this time since it is not decoding at all. 

I using an RTL-SDR and HDSDR software. I know that the RTL-SDR is not
the recommended hardware but it's what I can afford and it worked in the

If someone can offer constructive suggestions, I would appreciate it. (I
was climbing the telemetry board pretty quick and now I have come to a
halt. I'd like to get back at it.)
