Re: Measurement value for QRP Dummy Load - Peak or PEP? #alignment #dummyload #test

The DC voltage reading on the sense output of the dummy load is about 0.6 Volt too low because of the forward offset of the silicon diode used. Add 0.6 Volt to the reading first then do the Vpeak-to-power conversion. (Vpeak ^2 / 100).  Your QCX+ delivers about 3.4 Watts.
