You could try the Auto tune feature. Press the Priority/Transfer button when you catch a P25 comm.
The radio says NOW AUDIO TUNING1, the radio will automatically tune the numbers in the upper right (toward 0000) and then the radio has a double beep when it hits the optimum setting.
When auto tuning, the radio says NOW AUDIO TUNING2 and NOW AUDIO TUNING3 until tuning is completed.
You can then press “E” to lock in the new setting or “RSM” to get out of the Audio Quality mode.
Then press Manual followed by Trunk, and then Scan to resume.
