[4] The station can be heard during daylight hours in neighboring Evansville, Indiana and Owensboro, Kentucky.

[5] On December 17, 1941, ten days after the attack on Pearl Harbor, WSON first signed on the air under direction by Henderson businessman Hecht Lackey, who previously launched and managed WPAD in Paducah and WHOP in Hopkinsville.

However, a treaty between the United States and Canada signed in the mid-1980s allowed WSON and other daytimers that went off the air to protect Canadian clear-channel stations, to begin nighttime operations as well.

W243CU, which has an effective radiated power of 250 watts, can be heard up to 30 miles in any direction from its transmitter site in the Wolf Hills north of Henderson.
