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.
