. I've heard of the power being as high at 250,000 watts, but whether that was true or not, I don't know. Some have said the stations were pumping so much power that it was actually dangerous. Any truth to that?
There are numerous MW stations in the Middle East, Africa and Asia running 500 kw and more and a handful at 2000 kW.
These are transmitter output power levels, not ERP on gain MW arrays.
At these power levels, the operating staff stays away from the antenna systems and particular care is taken to ground everything which isn't supposed to be hot. In some cases, the fences around the tower structures are tied into the transmitter interlock circuitry, and in almost all cases, the doors for the tuning shelters are also tied into the interlock systems.
