Thank you too!

What fun it must have been in those days - no spark transmitters, modulated oscillators, indeterminate frequency stability, no EMC regulations to comply with. Interesting mention of the door interlocks on the transmitter, which disconnect the HT and also short-circuit the capacitors (hopefully through a resistance to avoid contact sparking!).
