[FedCom] ProVoice on Fed Channels?

[Chris Parris]

Got a question for the list...

Has anyone run into a federal conventional frequency that sounds like it
might be using ProVoice digital mode rather than APCO-25? 

I ask because I have run in to a couple of UHF federal frequencies that are
using some sort of digital mode that the APCO-25 scanners do not attempt to
decode. I wasn't sure what it might be, but recently I was able to listen
to some transmissions on an EDACS ProVoice trunked system and the sound of
the ProVoice transmissions seemed exactly like the "un-decodable" federal
UHF traffic...
