I see...Is the braid bare or insulated from the chassis? It might just be a way to peak rather than tweak the freq.
The circuit diagram indicates the braid is not grounded except through the
capacitors. Maybe someone with TMC equipment experience can chime in ?
The manual says to adjust the trimmers (which appear to be in series with the
xtals) in order to center the measured frequency on the indicated-on-crystal
frequency after the oven has been in operation for a while.
Are we geeks?
that's for sure, but I also do this in order to consume the time that I would
otherwise use to watch/listen to the (so-called) news.
I guess I'm really asking if I can use the circuit in figure 1 as a fundamental
crystal oscillator without having to worry about tuning the plate of the oscillator.
The multiplication chain I want to drive was covered in this thread
