At the time this aircheck was recorded, KWTO-AM was the big station in SW Missouri.  Nobody else came close.  The format was Country and their jocks were top-notch.  Even people who didn’t particularly like country (such as your author who was only 18 at the time) would listen because of the quality presentation.  At my location in Apple Valley, Minnesota, 560Khz was dominated at night by KWTO and WIND/Chicago.  I could separate the stations pretty well by selecting from multiple horizontal longwire antennas.  You can hear another station mixing in the background (which I believe is WIND), but KWTO still does pretty well.

This was received using a Pioneer SX-3900 receiver.  It was recorded on a Technics stereo cassette deck with Scotch Dynarange tape.
