Phil,I'm in Zone 08 and receive the Mendon (Chesnut Hill) site usually
on 860.8375. With my '780 in CCOM I can receive C talkgroups,
B talkgroups, A talkgroups, H talkgroups, and E Ptl 1, as well as
STATE and other statewide talkgroups. The '780 in this mode side by side with
an SP Motorola MTS2000 handheld or MCS2000 mobile programmed for C Troop as "home" in scan mode are identical,
they echo each other. Take that same MTS2000 and tune it to any
D talk group at the same location, and NO SYS is displayed, the radio
is "out of range" and will not transmit or receive.
The SP "field" (road troopers) radios are programmed so that they
have a "home" depending upon which troop the trooper works in. The
radios when in their home Troop can only tune their home (channel A1 on radio)
troop talk group and any bordering troop with
the exception of E PTL 1 which is available statewide.
When traveling to other troops, the talkgroups
become available when they are in range of the other troops or one that
borders it.
For example the C "home" radio can only tune D troop talkgroups
when in the troop D SmartZones or the bordering A/H SmartZones.
The C SmartZone does not border the D SmartZone. A/H and D radios can not
tune B talkgroups unless they are in C or B troop. The main
reason that this "bordering" troop talkgroup availability is used
is used is for pursuits from one troop to another.
I understand how the affiliations affect scanning, but my main
point is that for all purposes the CCOM on the '780 mimmicks
an MSP radio in scan mode for all purposes EXACTLY. For me that's about as
good as anyone with a scanner can ask for.

Brian
