This makes me think that what I thought was a crazy idea, isn't actually that crazy. If they are separated, that would mean we can have them tuned to different frequencies, right?

What I was thinking, was a transmitter control app that uses the receiver to monitor for noise (not putting it to the audio device, of course). If the noise gets to a certain point, it starts scanning other frequencies for somewhere it can get a clearer signal. When it finds a clear frequency, it tells the user to switch to that on the radio they're using.

Does this sound doable (or useful) to anyone else?
