Given the high number of "50 kW" AM stations near Detroit that use directional arrays with much greater ERPs than 50 kW in some compass directions...

Below is a graphic showing the fields at 1 km for transmitter powers of 0 - 500 kW when radiated by unloaded, base-driven, vertical monopoles having the four physical radiator heights described there.

I am glad there are no AMBC transmitters with in 1 kM of me :D
The two station Wixom site is 8.55 KM from me. :-D
I think the 1160 transmitter is running 15 kW now.
