Yes, perhaps you are right.  I was referring to data compression.  I was told we only send out linear PCM for broadcast, when I asked about file compression in relation to broadcasting. 

I'm sure our engineers are on top of it though, and really do strive to turn out the best sound for the listener, even taking the automobile environment into consideration.   

Again, we have no control over broadcasting other-produced files (NPR for example), or how other stations broadcast our material.

Allison, I think you're confusing data compression (as in .mp3 files) with audio compression (which manages the dynamic range of program

*Some* compression is necessary in broadcasting in order to avoid over-modulating the transmitter and splashing onto adjacent channels. If WPR (a network) isn't using audio compression, I assure you that the stations that broadcast your material are, in order to avoid breaking FCC regs about over-modulation. Audio compression, judiciously applied, also makes the material listenable in limited-dynamic-range environments, like cars.
