HI Rich, Thanks for the information, as it explains why I did not hear signals.
This is going to take awhile for this to become natural to me. I am learning this radio plus software as a hobby so I can take my time Merry Christmas Don KD8NNU On Fri, Dec 24, 2010 at 4:04 PM, Richard Ferch wrote: > Don, > > There are a few features of the K3 that might affect this. > > CW on the K3 normally uses the lower sideband.
