Lost P25 P1 control channels in multi-control channel playlist

leoninelion opened this issue · comments

sdrtrunk Version
0.6.1-beta-1

Configuration Environment
4 Nooelec RTL-SDR listening to 5 P25 P1 control channels for linked system

Describe the bug
After an unknown amount of time (can be hours to weeks) 4 of the 5 defined control channels will revert to IDLE, while one channel remains CONTROL. IDLE channel Messages indicate SYNC LOSS and the Channel graph is flat, showing no RX signal presence. Restarting the channels has no effect. The Tuners display shows all tuners Enabled and still locking frequencies (non-zero (LOCKED) displayed), suggesting all SDRs are still functioning. Reception of voice channels on affected control channels stops system-wide, including on Now Playing and streams. The remaining control channel still shows CONTROL and Channel graph shows normal signal presence and streaming. Resolution is restarting the application.
