[Elecraft] Synchronized and stable GPS phase lock for KX3, K3 and XV transverters

[Chuck Smallhouse]

GPS stabilized 10 MHz crystal oscillators are really an overkill, to 
be references for todays transceivers.

A good DOCXO, double ovenized crystal oscillator, is more than 
adequate, some even claiming accuracies of 10 parts to the -11th 
.   I have purchased several, through Internet advertisers, for well 
under $50, including shipping from Chinese surplus dealers.  These 
are usually American or Russian surplus units, that are being resold 
through these sources.  I've had repeatedly good and fast service 
from them.   Some of these advertise on E-Bay.

I also have Thunderbird and HP GPS stabilized units, as well as 
Rubidium standards, that could be used.  I find that their bulk, 
complexity and extra wiring is cumbersome and unnecessary, for even 
up to and including my 10 GHz operations.

On my K3/10, which I use for a lot of my V/U/ uW xvrtr needs, as an 
IF xcvr,  I even mount an OCXO, dead bug style to the inside of the 
'blank' rear panel of the K3/10 (with "Goop" adhesive), and run it's 
output to an SMA feed through connector.   I can then either use a 
SMA jumper cable to connect to the EXREF input, or to a power 
splitter, to also to be used as a 10MHz reference for my 
xvrtr(s).  This certainly makes a very simple and compact solution.
