This is for a university class. The specs are flexible, I can either find something that already does this sort of thing or build one myself.
The problem is with mobility. I'll have to be able to take this one on the road and verify it's functionality. I guess the problem is with conversion from the actual frequency to data. It'll take much longer to convert a LED display using the seven segment decoder if I hacked some digital radio. However, I don't need the audio just the frequencies.
