How far can a radio reach?
It depends…the environment plays a very large part in the range of a two-way radio. If there are buildings, trees, uneven terrain, other radio transmitting devices, interference, etc. in the environment, that will all have a negative impact on the range of the radio. So, the answer is, it depends.
