[Elecraft] K3 audio and rf inter reaction

[Ken K3IU]

I can't duplicate what you are describing here unless you are describing 
the normal noise I hear between dits and dahs when using full QSK. I 
hear no change at all in the sidetone at all. With FULL QSK, I do hear 
the the background noise between dits and dahs which one might call an 
artifact, but I think that is a normal thing with full QSK with a noisy 
band. Transmitting into the dummy load, the background noise is, of 
course,  much lower and so is the sound heard between dits and dahs.

Hope this helps!
