I was thinking of feeding two 10 Mhz signals to two ports of a SBL-1 or similar
and taking the DC
output at the IF port into an opamp or analog meter. This was visually easier
to adjust the drift between two frequencies by just watching the needle move. A
stationary needle over a couple of hours would be the best!
Raj, I did exactly this but with an old chart recorder attached to the
mixer IF port. This allows one to leave the room and not have to watch
for hours or days. I was able to adjust my -hp- rubidium unit this way
against gps to better than one cycle per day.
Low tech but effective.
