Not understanding a whole lot about the technical aspects of what distinguishes AM from FM, I'm puzzled as to why these AM broadcast modules require a dedicated crystal, whereas the FM transmitters usually have tunable frequency selection.
Also, I use one of the C. Crane/Sangean FM transmitters to play my iPod thru my Quasar GXD700, and have not been all that pleased with its performance. The Quasar sits on the headboard of my bed, and the Crane sits
right next to it, and I still sometimes have trouble getting a clean stereo signal. As far as getting it to work from accross the room -- very dicey. Maybe I'm doing something wrong.
I really like the design of the Crane, though.
