P25-1 failures when adding a 3rd site

[ah1102]

When adding a third site to monitor the P25-1 network, the newly added site fails intermittently. Separately, the site works smoothly.

-Thermal compensation enabled -0.6Hz for my device

What could be the reason, how to figure it out?

CPU load, in my opinion, is not extreme

[David-Forg]

Have you got enough bandwidth on your SDR to cover all 3 control channels?

[ah1102]

Yes, hackrf can set channel width up to 20 MHz

[ah1102]

There is another problem associated with this, that when monitoring 3 sites, the central frequency of the device can change for any channel width. This, as I noticed, can lead to errors in signal reception. The program does not block the frequency of the receiver, or at least check if the channel width is sufficient so as not to make unnecessary tuning https://github.com/DSheirer/sdrtrunk/issues/1033
