[time-nuts] Oscilloquartz BVA has been sold. Thank you all who expressed an interest.

Seconded!  I don't have that set up on all my oscillators, but plan to 
get there.  I *do* have things set up so I can remove the 24V battery 
bank for maintenance and run directly on the AC power.

BTW, I've standardized on using orange-black PowerPoles for 24V 
(red-black for 12/13.8V, green-black for 5V, etc.).  West Mountain Radio 
has 24V distribution panels with over/under voltage monitoring and 
orange-black connectors.

And, if you use PowerPoles, please spring the $30 and get a crimping 
tool.  It makes life so much easier, and connections so much more reliable.
