[time-nuts] Special connector for Symmetricom X72 rubidium standard

I'm going to buy enough boards to get them for a decent price... way lower than you can have them built for.  Will also probably do them with a kit of parts.

RDR Electronics has SA22's for not much more than the X72.   The problem with SA22's is the connector.  It is a dual row 18 pin connector with 2mm pitch.  It is on the bottom of the box where you want to mount the heatsink.   Not sure how one would mount it so that the full surface is on the heatsink.   It looks like they use a mating SMD PCB mounted connector.

I think that brings the best options for future use of the X72 
oscillator which seems to be a very good small rubidium oscillator 
nowerdays. SA22.c oscillators are not so spread over the known used-item 
reseller sources and if yes they are quite expensive to buy.
