KRLD - operates with a effective radiated power of 50,000 watts.
Probably when it was built, there were no houses where the transmitter is located. As urban sprawl continues, and property values increases, being in prime real estate becomes an issue.

I would think that there is a problem with their ground radial system, although 50,000 watts is enough power to light a light bulb next to the tower.

You could complain to the FCC, but since they have been licensed since 1925? you are not going to get much satisfaction.. The FCC might even tell you, if you didn't want to be exposed to that much RF, you shouldn't have moved there in the first place.

Or you can use Ferrite Beads on all the lines which will take away the common mode currents that are building up on the lines.
