I was never a ham, however, after WWII I was a kid and "played" with a lot of radios. Many military surplus receivers and and a/c transceivers were available then. It was like the "Golden Age" of radio.
I made a power supply for an SCR522 aircraft transciver and had a lot of fun with that. Also, spent much time with the old BC348 receiver. This was the one that you saw at the radio operator's table in the B-17. That was also a classic radio.
Somehow today, radio just does not have the appeal to me as it did then. I could draw, from memory schematics of basic transmitters and receivers. All kinds of "neat suff" abounded. Tubes, coils, transformers, pots, switches, etc.
Today it is all different. Just a micro chip does all that stuff and you can't very well "homebrew" these circuits.
I guess everything changes...just like it has in photograph. Nothing remains the same.

As an after thought, but on the same subject, here is a link to a story about an old transmitter that I saw and was aware of "back in the day."

A kid that was in elementary school with me had a father that was an electronics technician. He built this transmitter for another guy in the neighborhood.
This transmitter was used just a very few times prior to Pearl Harbor, and then ham radio was shut down...as well as this transmitter.
Back about 1947 the son of the owner of this let me have a peek into the ham shack. I remember it well. This is the same building that held this equipment until recent years when it was sold at an estate sale. I was so surprised to find these pictures.
