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 r
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.
It is MUCH less complex than it looks...
I will do a second draft with
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 :-)

The article I wrote and was published in QST, September 2015, gives
guidance to a method to determine the accuracy or lack there off, of
ones radio. Later the Freq CAL mode now available in WSJT-X does and
even better job. I've used this latest method, WSJT-X Freq CAL, with
a high degree
LOL! Well, it really isn't nearly as "complex" as it may look/read.
The complexity is largely "self-inflicted" due to:
a) the inclusion of a number of steps that for "normal" (aka: non-OCD)
folks are OPTIONAL,
b) my tendency to use 10 words when 2 will suffice, and
c) the inclusion of many "
Clay and all,
That is good work, but I feel it is overly complex.
The secret to using the zero-beat method for the Reference Oscillator is
in the ability to correctly tune WWV (or other standard station) to
zero-beat.
I make use of an audio spectrum analyzer running with my PC and
soundcard
It was not until recently that I acquired the TMP connectors and crimp
tool to make a proper jumper cable from my K3s' J1 connector on my K3s’
TXCO (TMP) to my frequency counter (BNC), so I have always used the
"zero-beat" method. Periodically, I go back and repeat the TXCO
calibration using a
