Amateur Radio 2 Meter 144 – 148 Mhz Band Plan

Band Plans in the Ham radio spectrum are not for the most part officially regulated by the FCC.

These band plans developed through the common courtesy and agreed upon “good practice” throughout the Ham community. They are arranged so that all transmission modes, technologies and requirements (repeaters, simplex, beacons, SSB, CW, etc) have their own slice of the action. Although it is true that no person or entity has a right to a specific frequency these are agreed upon spaces within the entirety of a particular band that have been proved throughout the course of Ham history to work for the common good.

The most widely used band in the VHF range is 2 Meters or otherwise known as 144 to 148 Megahertz.

144 – 144.10 CW (Continuous Wave) Morse Code signals

144.10 – 144.275 Single Side Band (SSB) operation

144.275 – 144.300 Propagation Beacons

144.30 – 144.50 OSCAR sideband (Amateur satellites that use digital transmissions such as ASCII for transmitting spacecraft telemetry on beacon transmitters.)

144.50 – 144.60 Linear Translator Inputs (Secondary Repeater)

144.60 – 144.90 FM Repeater Inputs

144.90 – 145.10 FM Simplex (Weak signal and antenna to antenna transmissions)

145.10 – 145.20 Linear Translator Outputs

145.20 – 145.50 FM Repeater Outputs

145.50 – 145.80 Experimental Modes

145.80 – 146.00 OSCAR Suband

146.01 – 146.37 Repeater Inputs

146.40 – 146.58 Simplex

146.52 National Simplex Calling Frequency (This is a national VHF Simplex frequency useful for daily monitoring as well as the primary frequency for non repeater emergency communications.)

146.61 – 147.39 Repeater Outputs

147.42 – 147.57 Simplex

147.60 – 147.99 Repeater Inputs

These 12 frequencies may not be used regularly in every location however they are available and very underused. Input these into your radio and you can use them as a starting point for scanning the simplex range. It is recommended to have these waiting and available in your memory bank for emergency communications if your local repeaters are down.
