I've gotten some good feedback from folks here on a couple of different issues, so I am looking for ideas again. This time I would like to ask folks who are using FM transmitters to get the music to folks driving by how you are letting the people know to turn on their FM radios and tune to the appropriate frequency? My idea is to go to the plastic supply and buy a piece of Lexan about 8" x 3' or so, attach white LED tapes to the plate spelling out something like "Tune to FM 89.8", and put it out by the curb. It doesn't sound very elegant to me, but it would get the job done, I think, and wouldn't be at all expensive. Surely someone out there may have a better idea, though?
