  2. Shortwave Listening Shortwave radio operates in the frequency range of 3-30 mhz In radio, short wavelength corresponds to high frequency given the inverse relationship between frequency and wavelength “shortwave radio” is received its name because its wavelengths are shorter than the longer wave-lengths used in early radio communications. Band names have evolved as radio technology continued to improve (HF, VHF, UHF, Microwave were coined as the technology developed.
