Part 15 FM station for a totally decorated X-mas yard.

A mile away, a neighbor of mine use to put up a u-FM station with X-mas tunage to accompany his totally holiday blingged out decorated yard. He's even got a lit sign that says "101.3FM". This year, that station now reaches 1/4 of a mile and is in stereo. Before, it maybe reached a two yards away. And last year, he didn't have it on. Anyone else come across X-mas decorated yard stations?
