I bought a KG-1000G (not plus) several years ago intending to put it in my off road truck. Instead I had another kid, my wife developed some health issues, and I did a couple remote assignments for work. It never found itself into my truck (which also needs some work). Fast forward, I got it out of the box and installed it in my shack instead.
Using an SW-33 power meter, I am getting power readings from about 34W in the simplex channel range and 32W in the repeater channel range.
If the radio is rated “50W” PEP as nearly all radios are but the SW-33 is measuring actual (RMS) Watts then there is only a small difference. I cannot find any mention in the brief (and obviously translated) documentation of the SW-33 if it is reading out true watts or PEP.
