[Elecraft] K3S glitching on startup

[Frank O'Donnell]

Thanks for the advice. Thankfully, there was a very simple solution. 
Although I had disconnected the CW paddle, as well as a number of other 
cables, I couldn't crane my head around enough to notice that I'd left a 
1/4"-to-1/8" adapter in the paddle jack on the back panel, which 
apparently had become partially unseated. When that was fixed, the 
problem went away.

73,
