I took some data from my master oscillator. I waited 3 minutes for
the oven to settle down before taking measurements. I set the
trimmer cap to a reference frequency of 10.00001 and went from
there. I used the Startek frequency counter with 10 Hz resolution.
Began at 20:30 and measured 10.00001
20:40 10.00002
20:50 10.00003
21:20 10.00004
21:58 10.00005
22:22 10.00006
There are some points where I observed flutter where the freq counter
was transitioning, so these times are not really exact, and only give
10 Hz resolution. However, there is a definite trend :-). Would
you all say that this is not acceptable for the Ten Tec OMNI VI
master oscillator crystal oven? Should I go out and fork over the
$50 for a new one?
I will check on my BFO next for good measure, it has been suggested
that problems can reside there also. I will check the trimmers in
different modes for alignment, and watch some of them to see if they
move much.
Thanks for all the comments and suggestions.
