[FedCom] ProVoice on Fed Channels? -Response Revised

[Arthur-Bryan E. Phelps]

During the past two years, several federal agencies have/are
awarded/awarding M/A-Com contracts for radio systems.  So, someone just
might have heard a ProVoice transmission on a fed. frequency, but I think
the probability is low.  By 2008 all agencies will be digital (as you
obviously know).  At this time, no one knows which system will dominate.
Some speculate M/A-Com, others Motorola/Harris Seneca or some future
technology that is lurking over the horizon.

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...
