Sell your home by recording a message & then have it transmitted - 24 hrs. a day - to a AM radio station 530-1700 kHz. Old technology but it works. When I was in real estate I used it dozens of times to help sell my listings. People drive by your house & see a sign that says 'for information' tune car radio to 'such & such' radio station. It's a cheap but effective way to market your property, car, boat, etc.
