[Elecraft] Strong Signals FD

[Wilson Lamb]

There's always something new... 
Our clubs went to 100W  this year, after being leaders in QRP for some years, up to #2. 
We wanted new hams and the SSB crowd to have more fun. 
I operated CW with one of my two K3, which worked fine, as usual. 
But I experienced something never seen before.  There was a 40m SSB station not far from me, with a dipole about 45 degrees and 100 feet away. 
I would occasionally get "Strong Signal" on my display, accompanied by very brief interruptions to my anility to change frequency.  I'd start turning the knob and the VFO would take 200-500 mS (guess) to respond. 
I also noticed the same thing re keying.  Sometimes the first dit or dah would be dropped when I started sending! 
Is this normal, common?   
It didn't cause a problem and there was no lingering effect.
