I have wondered if not amateurs could set up small frequency broadcasts

It's called a beacon and at least the UK license does allow them (25W
maximum) and there are a great many out there (mostly used for
propagation studies and the like).
Transmitter frequency stability will vary all over the shop, from non
ovenised microprocessor grade quartz, all the way up to GPS/Rb
disciplined Wenzel sprinter OCXO.
No, a beacon is something completely different than a transmitter
sending continous signal. The reason proposing something like 10 W is
that it would be reasonable electrical bill and maybe not cover a large
area, but still potentially useful.
There used to be a 10 W 100 MHz transmitter here in Stockholm for
instance, ticking of a cesium clock in Farsta.
