Two of the main types of radio tuning frequency, these stand for Amplitude Modulation and Frequency Modulation respectively. AM offers lower quality but larger range broadcasts; FM offers the best quality analogue broadcasts but at smaller range.
The two commercial radio systems in use in the US. Amplitude Modulation stations can be heard at great distances- especially at night, but are subject to interference and low fidelity. Frequency Modulated signals can only travel in a line of sight manner (generally 30-40 miles) but offer higher fidelity.
