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. I enjoy putt
