The 2-meter amateur radio band is a portion of the VHF radio spectrum that comprises frequencies stretching from 144 MHz to 148 MHz [1] in International Telecommunication Union region (ITU) Regions 2 (North and South America plus Hawaii) and 3 (Asia and Oceania) [2] [3] and from 144 MHz to 146 MHz in ITU Region 1 (Europe, Africa, and Russia).

Jan 22, 2022 · In particular, the 2m band extends from 144 MHz to 148 MHz. The FCC Rules say that any mode (FM, AM, SSB, CW, etc.) can be used on the band from 144.100 to 148.000 MHz. The FCC has restricted 144.0 to 144.100 MHz to CW operation only.

The 2-meter band is a very high-frequency band whose allocations typically range from 144 MHz to 148 MHz. In this article, we will discuss the 2 meter amateur radio band, 2 meter ham radio frequencies, and its characteristics.

Probably the most popular ham band in use today is the 2 meter band. Virtually every ham, young and old, has this band in his or her shack. The primary focus of ham radio operation on this band is using FM (frequency modulation).

The 2-meter band is a popular choice for digital packet transmission, with 144.39MHz (North America) and 144.8MHz (Europe) commonly used for APRS operation. Propagation Signals in this band travel primarily line-of-sight or slightly further.

Dec 2, 2021 · The 2M SSB calling frequency is 144.200 MHz, so that is the first place to look for activity or to call CQ. SSB operation is not channelized like FM simplex and repeater operations, so you’ll need to tune around to find other stations on the band.

Apr 7, 2025 · The 2 meter band offers longer wavelengths(~6.56 ft), which means that signals can travel further and bend around obstacles more easily. Conversely, the 70 cm band, with its shorter wavelengths(~2.3 ft), provides higher data capacity but typically covers a …

The American Red Cross has recognized that the 2-Meter Amateur band is a very effective way of providing communications during times of emergency and Ham radio operators provide 90% of the coordination efforts during a major emergency.

Feb 8, 2021 · The 2m band is very attractive for satellite use, with VHF propagation properties and manageable doppler shift for Low Earth Orbit (LEO) satellites. The downlink from the International Space Station (ISS) is usually 145.80 MHz.

Feb 3, 2016 · The term 2 Meters commonly refers to a frequency band assigned for Amateur Radio use. The band limits in the USA for the 2 Meter amateur band are 144-148MHz. 2 Meters refers to Wavelength. It means that the radio waves transmitted at 144 million times per second are 2 meters in length. See Wavelength for more information.
