I may come off ignorant but i have a real question, and was wondering if anyone would take the time and explane. I had a freind a few years ago who was the PD at KILE 1560AM here in houston and i remember hearing that he was using a sub carrier i'm not sure if this is the correct term or name but he was selling this special radio (not like a normal Am ,Fm sterio ) these radios would pick up his programing on what i belive was 90.9 here in houston and i belive only that frequency it's kinda wierd but i never understood how that worked but always wondered how 90.9 could do that i also remember seeing on a magazine radio caracol 90.9 here in Houston but it worked the same way .

Do sub carriers carry the same power and is this legal does the fcc get involved?
 
Essentially you are describing what is called sub-carrier audio. It’s only possible to do on FM stations. Here’s a link that explains it to some degree.

More correctly, <a target="_blank" href=http://www.fcc.gov/mb/audio/subcarriers>SCA</a> stands for Subsidiary Communications Authority.<P ID="signature">______________
