A few questions:
- Let's say someone breaks some FCC rules and can do whatever they want. Can an FM broadcaster change its transmitter frequency from the VHF band (example, 100.1 MHz) and put itself down in the MW band (example, 540 kHz) while still remaining FM, and still be receivable by analog AM radios, and listenable? And vice versa with an AM station increasing its frequency into the FM band with still remaining AM?
- I am hearing things about "all digital AM." Is this description a misnomer? The way I understand it, "amplitude modulation" is an analog process, whereas digital doesn't use amplitude modulation to decode a signal, although digital signals still travel on the same carrier signal. Is it more accurate to refer to all digital AM as "digital radio on the radio band we typically allocated for AM broadcasts"? (I'm not referring to anything hybrid-digital with my questions.)
