[Elecraft] Spurious signal after k2 click mod

[David A. Belsley]

Well, Vic, I've done some better testing this morning.  I called a chap 
across town to listen.  He couldn't hear anything wrong (but could hear 
a lot right).  Then I put the K2 on a dummy and listened on both my 
Drakes, 2C and R4B, and the signal sounded clean: no spurious signals, 
no clicks.  Last night, I had monitored my signal with antenna, and it 
is clear that what I was hearing in the 2C (but not the R4B) was just 
due to overload.

So I'm not sure what's happening with your K2.  How close to you was 
the chap who indicated hearing the spurious signal?  As I indicated 
last night, and as I showed again this morning, artifacts like that can 
happen with a very strong local signal.

best wishes, and good luck,

dave belsley, w1euy
