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