Some cold snowy morning, like this morning, I may sit down and hold a rtty
contest with it to try some more.  I'll likely check some of the switching
circuit today and make sure the bypass caps are in place and maybe add a
couple more on the external key input line where there doesn't seem to be
any... with all the rf around here that could be letting some in any maybe
doing bad things also... I have had an amp blow out its meter, an old home
brew 4-1000 I had picked up blew out its plate meter right next to my head.
Fortunately I was out of the line of fire, but did end up picking up pieces
20+ feet away across the shack.
