It has been a few weeks since I built the KSB2 option. There is one problem I haven't yet resolved. The response on the USB side of OP1 is not as broad as the LSB side, and has a narrower peak. I didn't pay much attention to this before. I've never transmitted in USB except for the digital modes using RTTY reverse. I'm not much of a SSB guy.
These observations were made with the Spectrogram software. The symptoms are quite noticeable by listening also. 73, Steve N6VL K2 #2289 _______________________________________________ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.
