This is a type of two way radio communication. These units can be found at Radio Shack, Grainger Supply, Northern Tool and Equipment, and many other national retailers. These units are primarily for short distance transmission.
radio transmission can be heard in hilly areas because of diffraction
Radio waves are in all parts of the atmosphere. Some, but not all, radio waves are reflected from the ionosphere, permitting transmission over greater distances.
