Regarding the Oscilloquartz 8600-3 that was 1 Hz off the frequency... 
I have received information off the listthat I think will be helpful.
I will give it another try.
Cheers

One of mine is off in similar sense. It can't be tuned to be sharp on 5
MHz anymore. The way that I use my main pair is as phase-noise reference
for the TimePod.

But, I'd love if I could tweak it back.

Cheers,
Magnus

Hi,
the BVA has a very small frequency calibration range.
I have solved this analogous problem on two 1000B by replacing the fixed capacitor which determines the base frequency of the resonance inside the oscillator.
I think it's the only way to solve the problem.
There are no wiring diagrams but with a little patience you can identify the capacitor and increase or decrease its value.
cheers
Luciano
