Thanks for all the replies. At least I know I'm normal, er, well the 
radio is at least :)

Had a good time with AA CW test this weekend just in and out of the 
shack an hour or two at a time and limiting myself to the K2 at 10 watts 
whilst the K3 and big Alpha sit idle. Very good to work into EU with the 
10 watts and completed with K3EST and K7QA both of whom have uuge! 
signals here is SE Asia tonight but still my first 2 USA with 10 watts. 
It's rare to hear US stations here and more so to hear them that strong.

Martin, HS0ZED
