Many countries require a license for radio users (such as the United States of America). 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.
