I kinda built this:
Only used a Navman Jupiter 12 and a Isotemp 118 12 OCXO (temp controlled frequency)
I had this stuff laying around.
I used an old Sony brick PS also (more junk)
It appears to work, the 10 KHz square waves from the Navman and the divided down 10 KHz from the OCXO line up.
It produces a lot of usable harmonics up to maybe 500 MHz also.
The square waves viewed on my scope were 12 uSec apart when it was cooler in the room and now they are 14 uSec apart. The alignment appears quite stable over days, I do not have time graphing capabilities at this time.
After they line up the output appears stable also.
What Phenomenon causes the Sq Waves to line up and stop moving relative to one another?
Is it "An odd kind of Sympathy?"
I confess I know just about enough to get into trouble.
