Work continues on the new multi-site, simulcast radio system for Androscoggin SO...
In addition, the old 155.6700 MHz T/R CTCSS 192.8 Hz CTCSS T/R (NAC 351 APCO P-25 Phase 1)simplex system on Goff Hill in Auburn, remains in-service for now.
The new simulcast system on 154.8225 MHz R / 155.5875 MHz T have towers in Durham (Fire Station / EOC), Poland (Ricker Hill at Poland Spring Inn) , Mechanic Falls (Pigeon Hill near Oxford Casino), Leeds (Quaker Ridge), Livermore Falls (Moose Hill, near Fayette), Hebron (Streaked Mtn, near Buckfield)
CTCSS is 206.5 Hz R-only on the 154.8225 MHz output on all towers.
Input CTCSS on the 155.5875 MHz T-side varies by each individual location.
This functional design is very similar to the Oxford County multi-site system, which avoids the expense and extra infrastructure of investing in a voting receiver system.
So far, in the absence of more "official" information, input CTCSS identified to date are as follows
85..4
100.0
136.5
151.4
241.8
At present, unable to ascertain which input tone goes with which tower = needs more monitoring for confirmation.
It is my understanding that features are in-place with the new system that blocks unauthorized "non-subscriber" radios to be functional in spite of the aforementioned.
