The 2-meter amateur radio band is a portion of the VHF radio spectrum, comprising frequencies stretching from 144 MHz to 148 MHz. In most communities, the local Ham radio operators own and maintain repeaters on the 2-meter band, which assists their communications by increasing the distance that they can communicate with each other while still maintaining the quality of an FM transmission.
ARRL 2 Meter Band Plan
- 144.00-144.05 EME (CW)
- 144.05-144.10 General CW and weak signals
- 144.10-144.20 EME and weak-signal SSB
- 144.200 National calling frequency
- 144.200-144.275 General SSB operation
- 144.275-144.300 Propagation beacons
- 144.30-144.50 New OSCAR subband
- 144.50-144.60 Linear translator inputs
- 144.60-144.90 FM repeater inputs
- 144.90-145.10 Weak signal and FM simplex (145.01,03,05,07,09 are widely used for packet)
- 145.10-145.20 Linear translator outputs
- 145.20-145.50 FM repeater outputs
- 145.50-145.80 Miscellaneous and experimental modes
- 145.80-146.00 OSCAR subband
- 146.01-146.37 Repeater inputs
- 146.40-146.58 Simplex
- 146.52 National Simplex Calling Frequency
- 146.61-146.97 Repeater outputs
- 147.00-147.39 Repeater outputs
- 147.42-147.57 Simplex
- 147.60-147.99 Repeater inputs
The frequency 146.40 MHz is used in some areas as a repeater input. This band plan has been proposed by the ARRL VHF-UHF Advisory Committee.
