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.

Newbie question however what is the effect of NOT having the calibration done
on a regular basis?
Thanks in advance!

I have both the EXREF and a GPSDO, which I plan to start using as soon as I
make the correct cable.
I wrote this procedure for the guy/gal who is new and/or doesn't have a 10MHz
reference, or a lab full of instruments. <smile>
It is MUCH less complex than it looks...
I will do a second draft with a distilled version of each iteration that omits the
commentary, beginner instructions, and labels the "optional" steps.

I’ve filed this away in case I ever need it. In fact, I’m going to try it step
by step (makes it easier to understand than just reading it).
The simplest approach though, if you’re OCD about cal, is to install the K3XREF
and plug in a decent GPSDO :-)
