ALEAutomatic Link Establishment-400 is an amateur version of the 2G ALEAutomatic Link Establishment standard. It is adapted to the demands of amateur radio emergency traffic handling. ALEAutomatic Link Establishment-400 was developed by Patrick Lindecker F6CTE. This mode was designed to be utilized in 500 HzHertz (Hz), unit of frequency, defined as one cycle per second (1 Hz). channels. It is an 8-MFSKMultiple Frequency Shift-Keying system with 50Bd. For tuning, the center frequency is 1625 HzHertz (Hz), unit of frequency, defined as one cycle per second (1 Hz)..
