Just saw a couple posts where changing the modulation from NFM to FM solved a lot of delayed unmuting problems. That would be great for everyone if this is a universally applicable fix!
Yes, I saw that and it was on a P25 Conventional System using a 536 which is a bit of a surprise. I would have thought it would need to go the other way FM to NFM to work correctly, but maybe the firmware in the 536 has some digital filtering errors, if so, it could be fixed with corrections in the firmware.
However, we need to get the word out and your post may help others give it a try and we will soon know if it helps or not and if it does on what systems.
Fingers Crossed!
