microTALK ® Range
Your microTALK ® radio has a range of up to 3 km
(2 miles). Your range will vary depending on terrain and
conditions. In flat, open country your radio will operate at
maximum range. Buildings and foliage in the path of the
signal can reduce the range. Dense foliage and hilly terrain
will further reduce the signal.

which automatically shuts off weak transmissions and
unwanted noise due to terrain conditions or if you’ve
