[Elecraft] KX3 freq stability module request

[mzilmer at magellangps.com]

Comment:
The K3EXREF for the K3 is locked to a 10 MHz reference (usually a Rb clock or GPS timing receiver).  Even with this external frequency reference, the K3's stated accuracy is "within 2 Hz".  

I ran the temperature compensation procedure on the KX3, and it's about the same accuracy as the K3 with the external reference.  At least I can't measure the difference using a freq counter with that same 10 Mhz GPSDO reference input.

The procedure is easy to follow and takes only about one hour to perform.

It only takes less than an hour, Mike. Surely you could spend the time going through the procedure rather than spending $s on such a module even if it will ever be available.

My KX3 does not shift more than 2-4 Hz  from 10C to 50C. It's well worth going through the procedure.
