[Elecraft] Spurious signal after k2 click mod

[David A. Belsley]

Vic:  This is interesting, because I worked KT5X later in the evening 
(on 40 meters).  I told Fred I had just done the mod and he reported my 
signal sounded great.  Later, when I was testing in response to your 
first posting on this subject, Fred was apparently still monitoring the 
qrg.  He heard the testing and sent me an e-mail that said:

Listening to you test.  The keying is clean it's disgusting ;-)

So it is clear that, from his previous experiences with you, Fred knew 
what he was supposed to be listening for and didn't hear anything.  Do 
you have access to a spectrum analyzer?
