Sort of Propagation is a problem with the US 530-1610 kHz broadcast band. During the day atmospheric ionization kills the sky wave and the ground wave propagation distance is short enough that stations can be assigned frequencies that don't conflict. At night all bets are off when the sky wave kicks in. There are assigned clear channel frequencies that can run 50 kW, but may need to use directional antennas. Local stations on those frequencies either reduce power or go off the air at sunset. https://en.wikipedia.org/wiki/Clear-channel_station https://www.youtube.com/watch?v=WPTfIPHLUcw The Mexican stations have X series call signs and some of them were running 250 kW, and not very fussy. Get down near the border and you might 'hear it on the X' when it overloaded your Walkman headphones. When I was in southern AZ 20 miles from the border I built a highly directional AM antenna so I could listen to the Phoenix AM stations and null out the X. I was envious of one of the X DJs. He could roll the 'r' in 'radio' for seconds. Rrrrrrrrrrrrrradio. I never could roll the r's in German too well.
