Hello all , I'm monitoring a large p25 system and many transmissions are sounding like Donald Duck at times just wondering if anyone else has this issue. Thank you .

Welcome to the world of encryption, and no your 668 nor any other scanner will decode it...sorry. 73, n9zasHello all , I'm monitoring a large p25 system and many transmissions are sounding like Donald Duck at times just wondering if anyone else has this issue. Thank you .

My guess is that it is voice-inversion, which is a weak analog form of encryption. It is easy to break and monitor but I'd get in trouble with RR if I explained it here.
I would agree with this analysis as well. :wink: 73, n9zasVoice inversion on P25 ? I don't think so.
The OP's problem sounds like multipath distortion. I often hear recovered audio on P25 sounding very robotic or duck like.
Encryption on P25 sounds more like bubbly water.
It's not encryption, it has something to do with the decoding as I can hear the voices except at times it sounds like SSB on AM ,. I'm thinking there's a setting either in the software or within the radio .

Greetings again ,
I'm not sure yet what it may be , simulcast distortion, or maybe that the digital signal is slower to recover and transmissions are piling. Larry, currently I'm located in Onondaga County where there's multiple P25 systems , public safety , fire depts. , rescue co.'s etc. sorry I didn't put that info in my previous posts. Thanks for all the replies .
