Brief facts about sitor:

SITOR is a system for transmitting text messages. It was developed in the 1960s by Koninklijke TNT Post as an improvement over radioteletype. Although it uses the same frequency-shift keying modulation used by regular RTTY, SITOR uses error detection, redundancy, and/or retransmission to improve reliability. There are two SITOR modes: • SITOR-A is used for point to point links. SITOR-A uses automatic repeat request to gain reliability. If the receiver detects an error, it requests a retransmission. • SITOR-B is used for broadcast links. SITOR-B transmits each character in a message twice to gain reliability. If the receiver detects an error in the first character, it uses the copy. If both characters are garbled, the receiver won't know what was sent. • SITOR-B by definition uses forward error correction, versus ARQ for SITOR-A.__###newline###__ SITOR sends 7-bit characters as a bit stream at 100 baud. The bitstream is FSK modulated with a 170 Hz frequency shift.

AMTOR - AMTOR is a type of telecommunications system that consists of two or more electromechanical teleprinters in different locations that send and receive messages to one another. AMTOR is a specialized form of RTTY protocol.

NAVTEX - NAVTEX, sometimes styled Navtex or NavTex, is an international automated medium frequency direct-printing service for delivery of navigational and meteorological warnings and forecasts, as well as urgent maritime safety information to ships.

Radioteletype - Radioteletype is a telecommunications system consisting originally of two or more electromechanical teleprinters in different locations connected by radio rather than a wired link. Radioteletype evolved from earlier landline teleprinter operations that began in the mid-1800s.
