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 not have the calibration and stability to allow Novices to use
VFO's. Even upper class licensees needed a secondary standard to check
their frequency (e.g. a 100 kHz crystal controlled marker.) Nothing
like the rigs today where we trust the dial to be very accurate.

The transmitter in the radio was CW-only, rock-bound on 80-40-15 meters only
when barefoot with just the HW-16. It took the external HG-10 or -10B VFO (or
similar grid-keyed VFO) to get you flexible transmitting not involving crystals.
