via HACKADAY: The Power Of Directional Antennas

AM broadcasting had a big problem, but usually only at night. During the day the AM signals had limited range, but at night they could travel across the country.

via HACKADAY: Why is Donald Duck on the Radio? Math Behind Single Sideband Explained

AM, or amplitude modulation, was the earliest way of sending voice over radio waves. That makes sense because it is easy to modulate a signal and easy to demodulate it, as well. A carbon microphone is sufficient to crudely modulate an AM signal and diode — even a piece of natural crystal — will suffice […]

Radio Stations in Puerto Rico Struggling

It’s hard to determine exactly how many radio broadcast signals still exist on Puerto Rico following Hurricane Maria.
