[Elecraft] K3 QSK

[Steve Ellington]

That's really strange Brian. With my mon. at zero, keying the rig yields 
zero thump. I wonder......If you decrease your power to zero if it has an 
effect on this thump....Or if you exit vox mode and key in PTT if there is a 
change. Just wondering if RF has hany bearing on the thump. This reminds me 
of my Omni V. I had to redress some leads and improve some ground paths to 
eliminate a nasty click.
