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

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.

Note: for accurate measurement you need to apply specific antenna and compensate with Offset dB parameter to adjust for antenna gain. Multi band highly accurate, calibrated antennas are normally used by EMC testing and cost thousands of dollars, which is not a cost-effective approach for a handheld device. Therefore, we provide full support for the included dual band 144/430MHz telescopic antenna with gain adjustment for each band. Other 50 ohm antennas can be used by adjusting offset gain accordingly. To select the new mode, click on HAM Field Meter option (not available if the currently selected module is the 2400MHz module, select the 50KHz-940MHz module for this mode to become available)

The HAM frequency bands currently covered are listed below
