trying to identify radio system

[bailly2]

there are a couple multicasted p25 radio frequencies near me. they both emit pdu, tsdu and other non-voice data. both frequencies transmit voice that indicated the users were only 3 or 4 miles away, so it seemed to be an input or simplex, but the voice traffic was multicasted.
any idea what is going on?

sorry if i put this in the wrong category, didn't seemed to be a right one

Post the frequencies.

You also might have better luck having this thread moved to the NJ forum.
