While much has been written and said about the power of WLW (like when it was 500,000 watts from 1934-1939), WCKY has done well in the "power department" as well over the years. For example, in the post World War II years into April, 1964, the station featured a country music show at night (a DJ playing records) which received various contacts from all parts of the southern half of the U.S.A. and even into the Caribbean. During the Cuban missle crisis in 1962, WCKY was one of the stations chosen by the government to broadcast in Spanish after dark in programs aimed at the Cuban population. I think it was the farthest north station to take part in those broadcasts (WLAC in Nashville and WWL in New Orleans were among others). In 1964, as a part of the promotion of WCKY becoming the flagship station of the Reds' broadcasts, the station held a contest for the farthest listener. The winner was a serviceman in Japan. The runner-up was a listener in West Berlin.
I am also aware of the receiving of WSAI-1360 in distant points at times. At night, the station can not usually be heard beyond the I-275 loop around the Tri-State area of Ohio, Kentucky and Indiana. Yet I have seen people in Harlan, Kentucky set it on their car radios in 1964 when it featured a Top 40 format and that is close to 200 miles away in the Cumberland Gap. I have also heard it fade in and out in south-central Kentucky. This is the first I've heard of it being received in Florida.
