STANAG-4285
STANAG-4285 is specified by the NATO (North Atlantic Treaty Organization) Military Agency for Standardi-
zation in "Characteristics of 1200 / 2400 / 3600 Bits per Second Single Tone Modulators / Demodulators
for HF Radio Links" (16. February 1989).

The modulation technique used in this mode consists of phase shift keying (8-PSK) of a single tone sub-
carrier of 1800 Hz. The modulation speed (symbol rate) is always 2400 Bd.
Using different M-PSK modulations and FEC (Forward Error Correction) coding rates, serial binary user in-
formation (raw data) accepted at the line side input can be transmitted at different user data rates.
