...circling around and around...
Moved the (new) filter caps up out of the way and grounded them to the
grounding stud on the rear panel. Chirp, chirp, chirp! Up - down - up - down,
chirp!
Monitored Lo @ 18.1 MHz on my K3 - solid signal even while the R-4A was happily
chirping away...
Monitored PTO on the K3 - chirp, chirp, etc...
Disconnected everything from the PTO... Chirp, chirp on the K3...
Put in a 10V zener to get voltage to solid 10.2V. Chirp!
When it wobbles and chirps, I see the trace of the 10V line on the scope
change. It doesn't drop or increase - it's just a change in the ripple,
apparently. If I tap the chassis under the PTO, I can make it wobble and
chirp. I'm not really understanding this in that this PTO is the one that was
working great in the T-4XB.
Could the power supply be starving even though the xtal oscillator is not
changing at all?
