Yes, precisely! This CW signal was so normal on 15 meters that I tried replying to it. Then I realized whose signal it was, and checked 40m, and there was the REAL signal. That's why I said it was splattering all over. The audio was slathered all over 40m for half the allocation, up into the phone segment and below 7 mhz downward. But the RF was so clear 3 bands away that I thought he was transmitting there. But I'm not as up on what can cause that, and thought it might be something on MY end, so I didn't want to lay anything even remotely like blame on anyone. For all I knew, it was something weird with my antenna, or my radio, or something else, like resonance with a guy wire (I've heard of that happening).
I'm not trying to badmouth anyone, I was just shocked that the signal was SO pervasive! -=-=-=-=-=-=-=-=- 73, Gwen, NG3P On Thu, Jun 10, 2021 at 1:06 PM Andy Durbin <a.dur...@msn.com> wrote: > "Harmonics should only be heard on the harmonic frequency, not splatter > across the entire band." > > That depends on whether you are talking about RF frequency harmonics or > harmonics of the modulating audio frequency.
