[Elecraft] K3EXREF Ext. Frequency Reference Input

[Wes (N7WS)]

No experience with any of them here (yet).  Looks like a Chinese knockoff with 
the Trimble name on it.  Might be perfectly okay but I wouldn't buy it for that 
reason.

I've looked into buying, put haven't pulled the trigger yet*, one of these:

Also available from in the USA from 
http://www.force12inc.com/products/gps-locked-precision-frequency-reference-low-jitter-gps-clock-450-hz-to-800-mhz-output.html

I've corresponded with Leo and been told that I could drive both my K3 (or 
anything else) at 10MHz while also driving my SDR-IQs at 66.66MHz.

*Since I now have a K3S with the high stability TCXO, I'm hesitant.
