I forgot to mention that in CW mode, a birdie due to high VHF/UHF signal mixing can often be moved or eliminated altogether by switching to CW REV (CW reverse, i.e. opposite-sideband-CW). The K3 works just as well either way, but CW REV moves the LOs and thus may move the birdie. 73, Wayne N6KR --- http://www.elecraft.com _______________________________________________ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.
