Saved wmv files from FM radio - are they lossy?

Are the wmv files created on the Sansa Clip from FM Radio recordings lossy or lossless?

i think the files are wav not wmv. wav is a uncompressed format however FM radio broadcast is pretty low quality so i would assume the broadcast is lossy regardless of the recording. 

And so if the files are wav files, that means the files are lossless to the transmission received, but that the transmission itself may be of lower quality, right?

You are correct!
