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!

at low speed the artefact sounds like a scraping noise riding on the string.
High speed it's like an extra edge.
Anyone confirm this, offer an explanation?
