Sampling rate has a lot to do with this. Then there's the quality of the MP3 unit's reproduction.

An MP3 that's sampled ~192kbit should provide a source signal well beyond typical fm radio's offered frequency response.

 

Anyone found a supplier of CB's with those comando neck mic's voice activated by any chance?

They are neat'o !!

And hair pin turns into 40km at 104km makes it tough to handle a tiny CB handset and drive!
