Hi Paul, Between prop delays and the carrier level modulation in the graph, it does look pretty bad. But as soon as you unlock the oscillator, it goes on its merry way with a very clean sawtooth.
The direction of drift is what bothers me. I have a lot to learn about crystal oscillators. Maybe I will make a 24 hour run and see it the direction switches are still occurring. Paul A.

What a mess. :-) Love LF propagation. Do not have a conclusion but I do see some of the same behaviors. Regards Paul WB8TSL On Wed, Aug 3, 2011 at 1:05 PM, Paul A.
