Not sure if you have made purchases etc, but Force-12 has 2 units (GPSDO) that
are made by Leo Bodnar available that have dual outputs.

I just got one of these.

BG7TBL also makes a matching 8 output sinewave distribution amplifier. It also
contains another Morion 10 MHz OCXO which switches in automatically if the 10
MHz input to the distribution amp is not there. You can usually get a good deal
on the GPS reference and the distribution amp together on

Found the unit works great as a master reference for not only the K3 but lab
gear like counters and
I see both a sine wave and a square wave version available on ebay. The
K3EXREF doc references both w/ regard to signal source, so I assume
either would work.
Initially, I'll only be connecting a K3, is one a better choice than the
other?

Back in the 1950's all radios drifted a lot at cold start...that is
why many let their receivers run continuously.

Yes, I bought one as well, along with the matching 8 channel distribution
amplifier which is equally well made.
There is a review by VK2XAX Tim Tuck of a later model which may have fixed that
tiny error in phase.
I also read an interesting article about the 5MHz leakage from the Morion

Ron,
The MV89A is pretty incredible-- especially for the price.
I think two statements in your posting contradict each other though.
It isn't basically "on frequency" from a cold start. It drifts 10's of
Hz until the oven temp and oscillator stabilizes.
The second statement about taking 40
I should also have linked to the USA importer of the Leo Bodnar unit

They are on eBay too, sometimes there are bargains the GPSDO and the

look for BG7TBL the designer.

Presently it seems that the Trimble Thunderbolt is the only reasonably priced

chance as they are refurbished and shipped from China. Some of these units are
better than others depending on serial number. Again, you
Wishful thinking? Yeah, probably, for the same reason Elecraft doesn't want
to get into the power supply business. There is a HUGE amount of
closely-held magic in both the precision oscillator and in the GPS

resources to
