[Elecraft] K3XREF Question

[Edward R Cole]

Just to add some info to what Chuck, W7CS, wrote:

I have both a Rubdidum and OCXO frequency standard in my shack.  Here 
is a webpage that shows how I installed them:

I run the OCXO as my 10-MHz reference for the K3 and VHF/UHF 
transverters (it is actually better than the Rb).  I paid about $45 
on e-bay for mine.  It has run continuously since I installed it 
(about two years).

Here is my beta test of the K3EXREF:

Hope this is helpful to those considering this topic.
