DIY RF Power Meter is “almost working” with reasonable temperature (C) and “close at about 3.5 dB low” power measurement for values > -20 dBm. RF level under range kicking in at -33 instead of -55 dBm. More debug work (and fun) ahead. #HamRadio #TestEquipment #NotLabVIEW
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!

Completed a quick blog write up for the DIY Stand Alone RF Power Meter. Now using this routinely in the home lab. Also captured the previous LabVIEW controlled RF power meter version at that site. The Mini-Circuits ZX47-55 sensor is now dedicated to the stand alone meter version.

@n8dmt very cool! That’s a lot of fun stuff in that photo, too!
@relistan … so many distractions, so little time … 73
