Ham radio simplex frequencies

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.
