of precise time and frequency measurement
Subject: Re: [time-nuts] Tracor 527A and 10MHz reference input
Dave will guess you are sub sampling the 10 Mhz ref.
Yes it should be 4.7K. Not sure why but old military gear resistors were like
that. Circa 1942 at least in schematics I have seen.

A friend says his Tracor 527A works fine with a 10MHz Ref input even though
it doesn't have the divide by 2 circuit from the addendum to the 527E manual
applied.
I'm puzzled by this - I can't quite see how the reference input circuit can
produce a 5MHz output when fed with 10MHz (unless his
