Jim, no, I don't really have a way to check for that.? I suppose I could use my SDR dongle as a poor man's spectrum analyzer??? See what other spikes I get in the spectrum when I transmit?
I will note that, at the low end of 80 meters, prior to turning up RV1, I was only getting ~6.5W, so I'm wondering if my uBITX wasn't quite adjusted right from the factory... I wasn't getting 8 W anywhere.? Although, that probably also gets to Dave's point about different power meters, different measurements.
