General Information
- Grafton County Sheriff's Office (GCSO) opperates multiple repeaters all having an output on 154.770, but having different NAC's to each.
- GCSO now opperates in APCO 25 Digital mode. All their primary repeaters (Cannon Mt, Tenney Mt, Moose Mt) still have analog technology as well with a PL of 136.5. Rarely you will hear units using analog if they are in a P25 "dead" spot. GCSO also operates on another repeater frequency (output 158.835). This is a Motorola Quantar Repeater located on Mt. Agassiz in Bethlehem. It is capable of P25 and analog transmissions. However 99% of radio traffic on this channel is Analog. The Alpha Tag for this channel is: "Grafton-North". Franconia, Sugar Hill, and Bethlehem PD share this channel.
- Lisbon PD is the only department that is still 100% analog on 154.980.
- GCSO dispatches sheriff's deputies and officers of the various communities as noted in Grafton County Police Departments
- Plymouth Police Dispatch PD's in there area using P-25 Digital, an example of an ID would be Plymouth Police Chief = 15-01 "Fifteen Oh One"
- Grafton County Sheriff's Office (GCSO) also dispatches many of the town PD's in Grafton County. GCSO dispatches entirely APCO 25 Digital except for Lisbon Police Department. They still operate using Analog communications. GCSO repeater system can still be used in Analog mode in the event P25 problems.
