[BC] AM Carriers

[Larry Bloomfield]

Richard:

That certainly is a much different way of looking at it than I've ever 
heard before. Perhaps you can explain what is meant by sub-carrier or 
doesn't that exist either. :-)  I think you may have really stirred up a 
hornets nest here. Think I'll sit back and watch the action on this list.
