But broadcasting a time that's incorrect by 7 or 8 hours?????
(difference
between UTC and PST/PDT).
Unlicensed operations are allowed on longwave frequencies, but they're
limited to one watt and the frequency range is 160kHz to 190kHz
("lowfers").
It seems more likely to me that previous tinkering with the watch
finally "caught up" with it, maybe after it convinced itself there
was no usable signal on 77.5kHz for some extended period. All a
guess,
of course: How someone could knowing how to set an analog watch is
still the biggest mystery to me.
