List of amateur radio modes

The following is a list of the modes of communication used by amateur radio operators.

Analog

*Amplitude Modulation (AM)
*Double Sideband Suppressed Carrier (DSB-SC)
*Independent Sideband (ISB)
*Single Sideband (SSB)
*Amplitude Modulation Equivalent (AME)

*Frequency Modulation (FM)
*Phase Modulation (PM)

*Continuous Wave (CW)

Image Modes

*Amateur Television, also known as Fast Scan television (ATV)
*Slow Scan Television (SSTV)
*Facsimile

Digital

Most amateur digital modes are transmitted by inserting audio into the microphone input of a radio and using an analog scheme, such as amplitude modulation (AM), frequency modulation (FM), or single-sideband modulation (SSB).
*ALE Automatic Link Establishment
*AMateur Teleprinting Over Radio (AMTOR)
*D-Star
*Echolink
*Hellschreiber, also referred to as either Feld-Hell, or Hell
* Discrete multi-tone modulation modes such as Multi Tone 63 (MT63)
*Multiple Frequency-Shift Keying (MFSK) modes such as
** FSK441, JT6M, JT65, and
** Olivia MFSK
*Packet Radio (AX25):*Automatic Position Reporting System (APRS)
*PACTOR
*Phase Shift Keying (31 baud) (PSK31)
*Spread spectrum
*Simplex Teletype Over Radio (SITOR)
*Radio Teletype (RTTY)
*8FSK 8ary Frequency Shift Keying

Modes by Activity

The following 'modes' use no one specific modulation scheme but rather are classified by the activity of the communication.
*Earth-Moon-Earth (EME)
*Internet Radio Linking Project (IRLP)
*Low Transmitter Power (QRP)
*Satellite (OSCAR)
