Years ago, pay music services used FM broadcast subcarriers to deliver there service. Those with some electronic savvy could build decoders. Wala, a receiver that picked up elevator music. Those same subcarriers were later used ( and still are in a few locales) for Taping for the Blind. Books and newspapers were read for blind people. Most of the larger AM stations here in Houston TX have digital broadcast. The digital broadcast are on the FM bands. Low band freq. do not work well with digital broadcasting. I still like to get on the 75 meter AM Ham band. I still like the tone of talking with someone on AM.
