Re: Oldsters
Oh, no! You had to bring up Heathkit ...
Wow, do I miss that company. I believe I built almost everyone of their kits, including a console color TV.
I used the Heathkit DX-60

driving into a 15' cubical quad antenna, which I also built, and got 5-9-9's out of Japan. Some reported my signal being stronger than 1Kw rigs using yagi antennas. Not bad for a 60 watt CW signal sending Morse code using a paddle. WN5VSX was my call sign.
I used to reach out the window and turn the shaft supporting the antenna to maximize incoming signal strength. So much fun .... But, alas, graduate school required all of my time. I never went voice and never returned to amateur radio after I finished grad school. My last heathkit project, was an EC-1 Alalog computer.

It's manual is located here and includes an excellent discussion of Operational Amplifiers and how they can be wired to solve 2nd order DiffEqs, with several excellent examples. I was using that computer in my 12th grade physics classes between 1974 and 1978. All my physics demos were switched to my Apple ][+, which I bought in the Summer of 1978,.
