I bought a pair of these radios to communicate with base camp when I am out photographing and filming. These radios are legal in Canada and produce the max power allowed under the canadian regulations, that is 2 Watts. In this video I attempt to determine how far you can clearly communicate with these radios. I show you the results with a map of distance and altitude variations. I also explain the difference between US and canadian regulations as they differ significantly.
