Re: Transmit Output Power (CW) #v5


Well ...anything you've got is better than nothing ...back in the old days, folks used a wave-meter (gdo in diode position) to check for spurs/harmonics ..was hoping for some before/after measurements...ah well

thanks, Jim

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.
