2 Meters

From Biocrawler, the free encyclopedia.

2 Meters is a popular amateur radio band. It ranges from 144 to 148 MHz in the United States, and from 144 to 146 MHz in most other parts of the world. The 2 Meter band is part of the VHF spectrum, and is primarily used for local communications, within a range of about 100 miles. Because it is local and reliable, and because in many parts of the world, the licensing requirements to transmit on the 2 Meter band it are easy to obtain, this band is one of the most popular non-HF ham bands.

Band Plan

Below is a common band plan for 2 meters.

Sample Band Plan

144.000 - 144.100 MHz	CW only, as restricted by FCC Part 97
144.100 - 144.275 MHz	CW and SSB
144.275 - 144.300 MHz	CW propagation beacons
144.300 - 144.500 MHz	Satellite
144.510 - 144.890 MHz	FM repeater inputs (600 kHz splits) FM repeater inputs are spaced 20 kHz apart (144.510, 144.530, 144.550, etc.) FM repeater inputs are coupled with outputs from 145.110 to 145.490
144.910 - 145.090 MHz	Packet and FM simplex Packet channels are spaced 20 kHz apart on the odd frequencies (144.910, 144.930, 144.950, etc.) FM simplex channels are spaced 20 kHz apart on the even frequencies (144.920, 144.940, 144.960, etc.)
145.110 - 145.490 MHz	FM repeater outputs (600 kHz splits) FM repeater outputs are spaced 20 kHz apart (145.110, 145.130, 145.150, etc.) FM repeater outputs are coupled with inputs from 144.510 to 144.890
145.510 - 145.790 MHz	FM simplex, digital and satellite Channels are spaced 20 kHz apart (145.510, 145.530, 145.550, etc.)
145.800 - 146.000 MHz	Satellite
146.010 - 146.385 MHz	FM repeater inputs (600 kHz splits) FM repeater inputs are spaced 15 kHz apart (146.010, 146.025, 146.040, etc.) FM repeater inputs are coupled with outputs from 146.610 to 146.985
146.400 - 146.595 MHz	FM simplex FM simplex channels are spaced 15 kHz apart (146.400, 146.415, 146.430, etc.)
146.610 - 146.985 MHz	FM repeater outputs (600 kHz splits) FM repeater outputs are spaced 15 kHz apart (146.610, 146.625, 146.640, etc.) FM repeater outputs are coupled with inputs from 146.010 to 146.385
147.000 - 147.390 MHz	FM repeater outputs (600 kHz splits) FM repeater outputs are spaced 15 kHz apart (147.000, 147.015, 147.030, etc.) FM repeater outputs are coupled with inputs from 147.600 to 147.990 In some areas, 147.000 MHz is coupled with 146.400 MHz as an input instead of 147.600 MHz.
147.405 - 147.585 MHz	FM simplex FM simplex channels are spaced 15 kHz apart (147.405, 147.420, 147.435, etc.)
147.600 - 147.990 MHz	FM repeater inputs (600 kHz splits) FM repeater inputs are spaced 15 kHz apart (147.600, 147.615, 147.630, etc.) FM repeater inputs are coupled with outputs from 147.000 to 147.390
