STANAG 4285 is the NATO standard for HF communication. It consists of several sub modes (75-2400 bps) and two different interleaving options (short and long). The waveform consists of a 1800 Hz carrier with PSK modulation.
These STANAGs are similar in principle to MIL-STD-188-110B, but differ in some details. Most notably they lack the “auto-baud” feature and are also incompatible with the 110A waveforms.
