[Elecraft] [K2] K6XX zero beat indicator and the "Spot" function

[Christopher Kimball]

I've installed the K6XX zero beat indicator on my K2.  It's a real 
improvement, for me, over the "Spot" button action.  Alas, it blinks 
distractingly on the no-signal condition with the RF gain at max. 
(Reducing the RF gain, fixes this, but I'd rather let the AGC do the 
gain control.)

Is there some point at which I can get a signal from the K2 that 
indicates the "Spot" function is active, so I can activate the K6XX?  
It'd be nice to eliminate the spot signal, too. 

Clearly, I don't understand where the spot signal comes from.
