What are the ham radio simplex frequencies?
Across all of North America, the National Simplex Frequency (also referred to as the calling frequency) is 146.52 MHz. In areas that use 15-kHz channels, the adjacent channels are 146.535, 146.550, 146.565 MHz, etc. moving upward. Below the calling frequency are 146.505, 146.490, 146.475 MHz and on.
What are simplex frequencies used for?
Simplex is also used in amateur communications. It is a sometimes called “direct” and uses one frequency in the amateur radio band to transmit and receive a signal directly to another radio. No equipment in between, just radio to radio.
What is 2m simplex?
For new hams who are likely to get started in local VHF/UHF operation, the national calling frequencies to be concerned with are 2m and 70cm FM simplex (non-repeater). These are 146.520MHz and 446.000MHz, respectively, and should be included in your radio’s scanned channels.
What frequency do most hams use?
For ham radio operators, you’ll use the frequency range from 420 – 450MHz. Unlike the reliability of VHF radio waves, UHF has a much shorter wavelength and is prone to interference from basically any solid object, whether that’s a building blocking your signal or even your body.
Which is the best frequency for Ham simplex?
In most areas it’s usually safe to operate simplex on 2 meters between 144.9-145.10, 145.51-145.79, 146.41-146.6 and 147.40-147.59 although in some areas some of those frequencies could be used for repeater inputs or outputs, RoIP nodes, or packet radio.
