No P2 Audio

I have a Nano that refuses to output any audio on P2 systems.. I see the talkgroup display on the WIO, The signal strength is -80, The P1 / P2 LED shows P2 but I hear nothing.. The Nano works 100% on P1 systems.. The audio is not muted..


What am I doing wrong?

The reference frequency needed to be tweaked..

Can't beat the Tech Support.. Sunday, Easter and I got 100% support... 

Bet you won't get that from Uniden or Unications !!
