Hi everyone,
I am using the R820T with SDRSharp and Unitrunker to monitor control channels. The issue I have is when I tune 418.1250 (Motorola P25 1) Unitrunker will decode the control channel info. About 10 minutes later the frequency will drift and I will lose the signal on Unitrunker. I then have to adjust the ppm usually by +1 to get the signal back This will happen about 3-4 times before it eventually stays on the frequency. My question is, how can I prevent this from happening? I understand that dongles need about 20 minutes to warm up but this issue only happens around the 418mhz range.
Hope this makes sense,
Larry
