OK - Actually, I thought it has already been *officially* moved - but
my guess is that there will be stations in places like Africa where
this regulation is loosely followed at best.

Do you know how much a new quartz crystal, custom grown, for a decades
old transmitter, costs?

Before PLL synthesisers you had to use a TCXO the size of a microwave
oven to provide sufficient frequency stability.

Fair enough. This little station, being perhaps a 1 kW station, might
be using just a ham rig and amp with an oversized power supply for
broadcast. In any case, the station rep said there were "propagation"
problems, whatever that means, so they were not using that frequency.
