So how come when listening to P25 trunking, the beginning of transmissions sometimes starts with what sounds like a short quick analog-style squelch tail noise? BURP!!! It actually happens right at the beginning of the transmission right when the user first keys up. It doesn't happen all the time, but it happens a lot. It never occurs on DMR, only P25. Why? Is there a way to get rid of this? It's annoying.
