Assuming you
1. Have tech MD set as ON.
2. Are on REF CAL and waiting to see the flashing asterisk and not
seeing it:
Then push the REV (2) button to be sure the k3xref is engaged.
I'm guessing you might have missed that last step. If so, wait a
short while & hope for the asterisk between

One thing you would want to set up different from the receiver's
defaults is the elevation mask.
Hey, great info, thanks. I am getting one

Hi Don and All
IMHO using a GPS disciplined 10 MHz (Trimble etc.) or a Rubidium
standards are unnecessary , expensive and overly complicated
approaches, to be used as the K3XREF 10 MHz external source.

...remembering the advice about voltage levels.
As far as I can see you can either use the ext ref continuously
(which was my plan) or you can use it as a very handy way
of re-calibrating the internal reference from time to time.
