Well, I think that MPT-1327 systems are actually a standard used outside
the U.S. I know that there are many systems like this in Europe, and in
some places MPT-1327 shows up on UHF, and I don't know if the standard is
SSB or FM in the UHF part, but I do know that there is a kit out there
that will let you trunktrack this kind of system even and it is based out
of New Zeland. It sounds like a PC interface of some kind, and MPT-1327
at least here in the states is rather odd in comparison to the
traditional Moto or EDACS.
