80m band Plan

Spectrum is the range of electromagnetic radio frequencies used to transmit sound, data, and video across the country . It is what carries voice between cell phones, television shows from broadcasters to your TV, and online information from one computer to the next, wirelessly.

The upper portion of the band, which is usually used for phone (voice) , is sometimes referred to as 75 meters. In Europe, 75m is a shortwave broadcast band, with a number of national radio services operating between 3.9 and 4.0 MHz.
