We are organizing a game for students where we are transmitting the daily objectives and hints over from an FM transmitter. Is there a way to limit basic radios to only be able to pick up a certain signal? For instance, 88.3 is not taken in our city, so would have the least amount of interference. We would like to limit it so that the student will dial through the stations (that will all be blocked) until they find the station that actually is broadcasting from a short distance away.
I hope that makes sense :)
