AM broadcasting. AM broadcasting is radio broadcasting using amplitude modulation (AM) transmissions. It was the first method developed for making audio radio transmissions, and is still used worldwide, primarily for medium wave (also known as "AM band") transmissions, but also on the longwave and shortwave radio bands.
[3] [6] WLS is a Class A station broadcasting on the clear-channel frequency of 890 kHz with 50,000 watts, using a non-directional antenna fed by a Nautel NX-50 transmitter, with a Harris DX-50 serving as a backup transmitter. Both transmitters run in MDCL (Modulation Dependent Carrier Level) mode to improve efficiency.
