Steve, Is the chirping "clocked" or more "free running" in nature?

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? 73, Steve Wedge, W1ES/4 "I can't complain, but sometimes I still do." - Joe Walsh If the above message appears, it came from Steve's Son of Laptop! -----Inline Attachment Follows----- _______________________________________________ Drakelist mailing list Drakelist@zerobeat.net http://mailman.zerobeat.net/mailman/listinfo/drakelist
