If the stated "12-1am" is the time KYND was heard in central Europe, that time zone would have a difference of +7 clock hours, so midnight to 1am there would be 5 to 6pm here. In March, KYND's sign-off time is 630pm. The hour or two prior to sign-off is a typical time for long distance AM signals to travel much farther than usual, especially when headed from west to east where darkness already prevails.
KYND being heard in Europe is a huge leap in believability, but that period of time might have been an atmospheric event for the ages. KYND is forced to cut power from 25KW to 18KW at the time New York's AM 1560 WFME (formerly WQEW) reaches its night-time hours, about one hour before KYND signs off, so that makes it an even bigger leap to accept that an 18 KW Houston radio station could be heard in Europe, but stranger things have happened. Who knows, maybe a European investor will decide to buy time on KYND thanks to Bill Turner being heard "across the pond."
