FCC Technician Exam Question Of The Day (T8B11)

Q) What is a commonly used method of sending signals to and from a digital satellite?

A) FM Packet

NJ2X Notes:
FM Packet

Packet radio is a digital mode of Amateur Radio communications which is similar to computer telecommunications employing modems. The telephone modem is replaced by a "magic" box called a TNC (terminal node controller) while the telephone system is replaced by amateur radio transceivers and amateur radio waves.   Packet radio transmits a stream of data from a computer via radio to another amateur radio station.  FM packet radio transmits using frequency modulation.
