You learned to know your rig and when to be careful. As a teenager, I
had a 2700 volt open breadboard power supply.

Back in those days, Novice class licenses were required to operate with
crystal control. You learned to tune at least 10 kc/s (kHz came later)
each side of your frequency after calling CQ. Novice segments were on
80/40 and 15m CW only. 2m AM and CW was also allowed. Rigs in those
days did no

Took a look at Heath's HW-16 design. Quite ingenious: Using the PA
cathode bypass capacitors and current through a diode to shunt the
receiver front end during transmit. Early diode QSK operation. And a
neon bulb relaxation oscillator, using grid block keying voltage, for CW
sidetone.
