Any advice or hints on getting scope.py tuned and then to stay tuned?
(I'm trying to listen to New Jersey Interoperability Communications
System -- P25 Phase II -- in case it matters.)
When I first played with op25 a few months ago, I stuck it on a spare
computer with a NooElec SDR dongle. Took a little futzing but I had it
up and running in a day or so and it actually stayed working perfectly
for close to 6 weeks. But this was just a test so that computer wasn't
on a UPS and shut down during a power failure.
Same hardware and I haven't been able to get it to stay tuned for more
than a few hours since. Figured maybe it was just the SDR dongle
drifting so I bought a RTL-SDR dongle which is supposed to drift less
but I'm still having problems getting the system to tune for more than
30 minutes or so.
Your thoughts are appreciated.
Thanks,

Got the ppm adjusted?
Use kalibrate to find your offset
