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,
