DIY RF Power Meter Achievement Unlocked (initial functionality achieved). Reviewed code, made tweaks, found cal-offset magic numbers and calibrated temperature (single point) and input RF level over -55 to +5 dBm at my test oscillator’s frequency of 100 MHz. RF Power Meter works stand-alone (no PC). Would like to add serial output data in future, but no rush at the moment. Thanks to DL9SEC for sharing his Arduino code for a similar RF sensor!
