KX3 and GPSDO?

[Frank O'Donnell]

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

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

Thanks and 73,

Frank K6FOD

Frank,

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.

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.

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.
