[Elecraft] K3EXREF Questions

[Ron D'Eau Claire]

That's right David, my memory is failing me today. 

If you apply an external reference signal the asterisk will appear.

The asterisk will flash as long as the external source is controlling the
K3's reference oscillator.

If you disconnect the external source the flashing stops but the asterisk
remains. 

If you disconnect the external source and re-start the K3 (power off/on)
there will be no asterisk until the external signal is applied again. 

At least that's how my prototype works.

Ron - Shouldn't the asterisk be blinking if the K3 is being controlled
by and external reference?  The presence of an asterisk merely indicates
that it has at some time been controlled by a reference since the last
power-up.
