RF Explorer HAM Field Meter License

Starting with firmware v3.25, all RF Explorer PLUS models can perform specific W/m2 or V/m measurements for all sub-GHZ popular HAM frequency bands. This feature is developed with contributions from Martin Lynch & Sons ( www.hamradio.co.uk )

You can use this feature to convert RF Explorer Spectrum Analyzer into an effective, accurate and easy to use Field Meter to easily check power levels being transmitted by your antenna at a reference distance, and check if transmission levels are in compliance with local regulations.
