[Elecraft] RX~TX Pops above 11w with KPA installed.

[Don Wilhelm]

Dave,

I suspect you also have the KDSP2 installed.

Try increasing the setting of T-R delay.  Also EDIT the T-R parameter 
and push DISPLAY to toggle between 8R NOR and 8R HOLD - use the one that 
reduces the pop better.

The situation is apparently caused by the delay through the KDSP2 which 
modifies the mute timing and causes a pop on unmute.  There is some (yet 
undefined to me) influence from the KPA100 T/R switching.  If you have 
an older KPA100 (before Nov 2006) adding the KPA100UPKT to your KPA100 
may help.  Why this appears on some K2 and not others is an additional 
mystery I have not yet figured out.

73,
