YouTube contributor shango066 has produced one of the most fascinating station tour videos I've ever seen. It is of AM Stereo C-QUAM station KYET-1170 in Golden Valley, Arizona. KYET broadcasts daytime 6,000 watts to a 190 ft. monopole tower, omni-directionally, and 1 watt at night.
See AM broadcast radio at its grittiest in the desert of western Arizona!
