[TrunkCom] does anyone know how the new scanners will handle both data and voice from the same channel?

[Wayne M H]

The good thing about the 9600 baud control channel is it isn't
strictly Motorola. The 9600 baud control channel is basically the
APCO-25 standard, with relation to trunking.

If you ever get a chance to see the standards themselves they are well
planned out and include for everything. They also go into exact detail
on how everything works. Creating a scanner, or whatever, to track
would be a snap.

The nice thing is the APCO-25 trunking control channel format will be
the same, no matter which vendor, so you can use different APCO-25
trunking radios. Just keep in mind that a vendor can create there own
signaling words strictly for their network and radios. But I believe
the basic call setup and process should be something that would be
decodeable by any APCO-25 trunking radio. The 9600 baud control
channel seems like something tough now but give it time, it won't in
the future.
