My grandfather was an early HAM radio operator and TV engineer, my dad still has some of his old equipment and the tuning dials are in cycles rather hertz, I grew up hearing him say kilocycle and megacycle.
I'm blown away at the fact(?) that they got that thing to oscillate at 146 MHz. Wasn't aware that any transistors with an fT that high could be made in the early 1950s.
