[Elecraft] Zero-Beat Procedure for the Elecraft K3s (DRAFT)

[Clay Autery]

Probably not a lot other than your transmit and receive frequency NOT 
being what is displayed on the VFO display.  I'm not a digital guy, but 
I suspect that it is perhaps more a concern for those guys.

I like to know that I am transmitting as close as I can to "on-freq", so 
if I am receiving reports of frequency issues that it is either the 
OTHER guy that is calibrated wrong, or I have another issue like an 
RIT/XIT offset uncleared.  I DON'T have to worry about my local cal.

As an aside...  AFTER setting REF CAL as accurately as possible using 25 
MHz, I then go and calibrate the P3 to set the center freq. precisely at 
the peak of the incoming signal from WWV.

As I am about to start feeding my K3s with 10 MHz from a GPSDO, REF CAL 
will be largely a thing moot concern, but I still do it periodically to 
monitor the aging process on my TXCO.

73,
