- 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
