It's been awhile.
Wow, does time fly. It's been an exceptionally long and cold
winter. Spring is right around the corner, but it did snow 2 inches two days ago. The KT-77 tubes have not broken-in yet,
can't hardly wait till they do. I made contact two weeks ago with a friend I knew when I was much younger. He still lives
in Georgia and was getting his 3rd divorce! We talked for an hour on the phone. It's a small world with all this network stuff.
The XYL has been in Colorado for the weekend so it was me and the animals. I'm teaching four classes this quarter. Three basic
and one advanced. I guess I should know it by now, but I'm always amazed by how little many people know about computers. Of
course I know very little about a lot of things, so what the hey. My 16 year-old Pyramid 35A power supply went out on
me. I took out the 2N3771 power transistors and tested them with the meter. Two had a base-collector short. I ordered four
new ones for about 10 bucks, put them in and it's working again. Gave the old Heathkit SB-221 a workout last night. The Ts-520
was putting out 140W on 40M and was driving the 221 to 1500W. I got a little concerned for my antenna balun so I cut
it back. Still, it was nice to know that the 3-500Z tubes are still kicking it out. The 6146B's weren't doing too badly either.
Oh well, another day in the boring life of a Ham Radio operator.
