Re: 3rd harmonic on 2M. Any fixes?
Hi Al,
Thanks for the feedback, and I get that, but the issue seems too consistent. I can transmit into an antenna or dummy load, 1/2 watt or 5 watt, and it still happens. I can tune the 2M side up

Re: 3rd harmonic on 2M. Any fixes?
You are in the near field and possibly picking up radiation from within the radio.

not 446.264 mhz as you indicate. Typo error, I assume?? Also-does the
undesired ("third harmonic") signal show up when you
