Here in Indiana WWL is very clear at night, and sometimes faintly comes in during the day during Winter... I have for years often heard a faint sounding Beeping like Morse Code in the background,,, Like WWV in Colorado on Short Wave, WWL was always much stronger and would have likely covered up speech from the Cuban Beeper station.... Which is what Indiana DXers call it.... Other Cuban stations include AM 710 Smashing out WLW, and 570, also a ticking station,,,, probabably the main channel for the 870 beeper. i found out in early 2000 that the 870 beeper was cuba,,,, before that I had no clue.... But WWL is so strong hear it often bleeds into WCBS,,, but WCBS has bled into WWL as well,,,,, a good Analog AM radio from the 80s or older will pull the two apart.
