About the author
Russel Dewalt
General Radiotelephone Operator. Technical consultant to Echo Radios.
Russel has spent 17 years installing and maintaining two-way radio systems for construction firms and municipal fleets. He reviews Echo Radios' technical guides for accuracy, including how coverage, networks and group calling actually work.
His job on this blog is accuracy. Before a guide is published he checks the radio-service rules it cites, the coverage and network claims, and anything that describes how group calling, encryption or battery behave in practice. Where a claim cannot be verified, it does not run.
