[time-nuts] Strange effect with C-Field change -- and a bit of data

I did some testing today and I think that strange effect I saw was in 
fact a cable problem -- I couldn't reproduce exactly the same effect, 
but in gently wiggling one of the cables to the counter I was able to 
get some oddball readings.

A couple of unrelated points -- I wasn't sure about this, but have 
verified that the FTS tube installed in my 5061A has the same C field 
sensitivity (8x10e-14 per minor division) as the original HP tube.   
And, having now seen the FTS instructions for retrofitting their tube in 
the HP chassis, I can verify that the Zeeman frequency for the FTS tube 
is supposed to be 42.82kHz.
