The system of maritime mobile communications utilizing HF radio narrow-band direct-printing telegraph (HF marine telex) is expected to see expanded use during the next several years. Experience has shown the necessity for the system to embody both automatic error correlation techniques and effective means of selective calling. Use of SITOR error correction has demonstrated that error rates in the order of 10-5 is a realistic expectation. Two selective calling methods, the sequential signle frequency code (SSFC) and the digital selective calling (SELCAL), have been adopted internationally, although the latter is still subject to final definition of technical characteristics. HF marine telex avoids most of the problems encountered with manual Morse radiotelegraph. It is tried and proven, efficient and economical.
