70cm Band

The 70cm band refers to a range of radio frequencies around 430 to 440 MHz used mainly for amateur radio communications. Named for the approximate 70-centimeter wavelength (since wavelength and frequency are inversely related), this band is popular among hobbyists because it offers good signal quality, penetration through obstacles, and relatively wide communication range. It’s suitable for local to regional contacts and can support various modes like voice, digital, and data transmissions. The 70cm band is part of the UHF (Ultra High Frequency) spectrum and is allocated internationally for amateur radio use, fostering community and experimentation for licensed operators.
