Notes and Definitions

7.5 kHz "narrow-band" frequencies will round off when entered into older scanners. Example: 155.2425 may become 155.245. Signals will still be audible.

Talkgroups listed in Uniden decimal format.

VHF repeater inputs are the only ones listed. UHF repeater inputs are 5 MHz above output unless specified otherwise, 800 MHz band repeaters are 45 MHz below.

Fireground frequencies and repeater inputs are almost all very low power (5 W, ±) and hard for me to confirm, so I'm not going to keep track of confirmations anymore.
