[Elecraft] K3 huge noise

[DAVID M. Elliott]

Lyle hasn't got it yet!!

Firmware 3.30 -- using NR (3-4) on SSB (14.178), first the volume  
control did not work then after a little while the K3 goes to full  
volume and only turning it off gets rid of the problem.

THIS IS A SERIOUS PROBLEM!!!  Hearing loss could result.  Please got  
on this ASAP.
