PX3 display artifact caused by Elecraft USB cable

[Elecraft mailing list]

Hello - I recently purchased a PX3 to support my QRP contesting efforts and am really glad I did. It really helps streamline S&P during contests.


However, when I plug a brand new Elecraft-provided USB cable for connecting the PX3/KX3 into my two-year old HP Pavilion PC, a 3-4db artifact appears on the PX3 display. No audio is associated with this artifact but it's distracting when viewing the PX3 display.


I'm certain the cable is the source of the issue because once the USB cable is unplugged the artifact disappears.



Can anyone suggest a resolution, or is this a known issue?



Thanks for taking time to consider this.

Are you sure this might not be an issue with electrical noise sourced from your PC?  I haven't had any such issues with my PX3 using the Elecraft cable.

I seem to remember a spike a bit right of center. I recall this appears when no signal or light signals are present. Stronger signals will diminish this artifact.
