Radio is working fine except for the following...1. Misses some transmissions (compared to Pro 106 side by side). 2. A popping sound during tranmissions. 3. P 25 phase 1 or 2 audio is either normal voice or an annoying ducky voice. Any thoughts on how to correct these issues?
Thanks,
Larry

Some have mentioned that if the DSPLevelAdapt (in the P25 advanced settings) is set above 74 you may get a ducky voice. The default is 64.

TRX-1 duck voice

Duck voice? sounds like you're hearing encryption to me. The DSP level adapt doesn't have anything to do with that - The DSP level adapt is defined AS: DSPLevelAdapt Controls how fast* the DSP adjusts to varying P25 levels. Lower values correspond to slower rates and higher values correspond to faster rates. Small adjustments (2-4 notches) are recommended.
Mine is 254. I've had it at 64, 100, 15 and now 254 and it never caused any duck voice. It sounds like you're either hearing encryption of a talk-group you forgot to lock out OR the Phase II TDMA voice which is louder than normal. OR the scanner's broke.
