2 Meter Ham Radio Band

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.
