Re: [Elecraft] KX3 and GPSDO?

2019-05-03 Thread Edward R Cole
If you are concerned about 6m frequency stability of the KX3, perform 
the temperature compensation procedure.  I cooled my KX3 in the 
refrigerator for 30-minutes to do mine.  I also added an after-market 
heat sink:

I used my XG3 checked against EIP538 freq counter.

Thanks, Don. For now I'll stick with plan B (GPSDO inputs to signal 
generator, the output of which is compared in Spectrum Lab to the signal 
under study delivered by the KX3). At least until I can save up for a K3S.

There is no native capability for that in either the KX2 or KX3.

Most anything is possible, but it would take some design and 
engineering by the KX3 user to add GPSDO input capability.


If you do not have those design and engineering skills, I suggest you 
don't try.

Frank,

KX3 owner, fairly new ham, interested in frequency measurement ...

Am I right in thinking that a KX3 can *not* be slaved to a GPSDO?
