[Elecraft] K3 audio and rf inter reaction
Mode: cw, paddle sending string of dots or dashes any speed power o/p: any, ie nil to max, dummy or antenna filter: any, but more pronounced 1kHz listening to side tone on phones or speaker audio control: max rf control: start low and raise until the artefact appears or rf: max audio: low and raise until the artefact appears 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?

Re: [Elecraft] K3 audio and rf inter reaction
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! 73, Ken K3IU ~~~ David Cutter wrote: Mode: cw, paddle sending string of dots or dashes any speed power o/p: any, ie nil to max, dummy or antenna filter: any, but more pronounced 1kHz listening to side tone on phones or speaker audio control: max rf control: start low and raise until the artefact appears or rf: max audio: low and raise until the artefact appears at low speed the artefact sounds like a scraping noise riding on the string.

Re: [Elecraft] K3 audio and rf inter reaction
The effect is also present with monitor at zero. In this condition, a rushing sound is heard. At a guess I would say it is digitally induced noise.
