[time-nuts] OCXO Adjustment Question

[J. L. Trantham]

It's nice to have something to do.

Sorry to hear of the 'bad' magic but, at least, it's not the same problem
all over again.

Well, I also had some bad magic happen.

Last night, I decided that I would shutdown my HP 8935 so that I could 
move it back to its usual place.  When I turned it on this a.m.  it 
wouldn't power up.  There is a known failure mode in the power supplies 
of the 89XX series.  I will probably just do an exchange for a re-built 
supply.

It looks like I will have a new project for next weekend!
