I recently built and installed a KSB2 in a K2...After the K2 warmed up
for a few minutes, a crackling noise started, and gradually got bad
enough to drown everything else out...It was caused by the lower ground
plane at the front edge of  the SSB board just BARELY touching the ground
wire soldered to the top of crystal X5's can...Moving the ground on the
crystal can cleared it up...

Subject: [Elecraft] KDSP2 Anomolies

I was operating USB on 17 meters today with a 1.4:1 SWR.  I don't know if
the 
SWR had anything to do with the K2 saying that the KDSP2 was NOT
INSTALLED 
after leaving the rig on and returning after about 2 hours and noticing
the 
anomolie.  I turned the K2 and power supply off, and after a few minutes
I turned 
it back on and the KDSP2 worked normally.  I tried to duplicate the
conditions 
on 17 meters, but couldn't get the KDSP2 to act up.  This is the first
time I 
have experienced this and wonder if something might be wrong.  I also
hear 
some crackling on the received SSB audio with the KDSP2 on but with the
noise 
reduction and notch OFF.  Sometimes its barely detectable and other times
its 
definitely there.  I would appreciate any thoughts on this.  Roy  W4WFB
