    You can check the following things:
    1. Verify the power settings of Channel Group 0, normally the non-hopping channels, and the other channels, Channel Group 1, etc., maybe they can be different.
    2. Check the parameters of down regulation of power control, they may have an improper setting.
    3. Check if you have antenna crossings in different channel groups.
    4. You can have an improper definition of channel groups about what antenna is assigned to a specific radio unit.
    5. Maybe you can have a defective radio unit, for example you are camping in the TRX with BCCH in non-hopping group and this is good, but when you start calling then you are moved to hopping channel this is bad.


    I hope this can help you, best regards,

    P.S.: I couldn't see the log file.
