[Elecraft] Popping noise on my K2

[Scott McDowell]

Hello
My K2 makes a popping noise when keying it on cw.  I remember when I was a 
kid my mother
would wash the bed sheets and hang them on an outside clothes line, and if 
the wind was
blowing the sheets would make a popping sound. That sounds exactly the same 
as the noise
I am hearing on the K2. It's almost as loud as the side tone. This happens 
at all power output
levels from 1 watt through 100 watts.
Has anyone had this same problem, and if so, how did you cure it?
Thanks
Scott N5SM
