[Elecraft] Pops and clicks on send

[Stephen W. Kercel]

Fellow Elecrafters:

I've developed an apparent problem with my K2.

When I send CW in the QRO mode, I hear a lot of pops and clicks in 
the sidetone and a loud pop when I stop sending.

When I'm in QRP mode this does not happen.

When I'm in QRO mode, it happens on all bands, whether I use a dummy 
load or a real antenna

It is very loud on 80 m barely audible but recognizable on 10 m and 
generally decreases in strength with increasing frequency.

The problem did not show up until a week or two ago, and then 
happened only occasionally. Just today it stared happening all the time.

I do not know if I have clicks on my transmitted signal. Nobody has 
complained about key clicks on the air.

Any advice would be greatly appreciated.

73,
