VHF RADIO USAGE
Many countries require a license for radio users (such as the United States). Be sure you comply
with all local laws while operating a VHF radio.
Surveying in RTK mode has made VHF the most popular choice for communications between
base and rover receivers. Know the strengths and weaknesses of this technology to get the best use
out of your receiver.
The quality and strength of the VHF signals translates into range for VHF communications.
The system’s range will greatly depend on the local conditions. Topography, local
communications and even meteorological conditions play a major role in the possible range of
RTK communications.
If needed, use a scanner to find clear channels for communication.
