SITOR-A is one of two modes of SITOR, which stands for Simplex Teletype Over Radio. Based on CCIR 476-4. It was formerly used to transmit maritime short messages, however the maritime industry is gradually moving away from using this mode in favor of PACTOR. AMTOR is a type of SITOR used by amateur radio operators.

Frequencies
One of the biggest users of SITOR-A is not a maritime service - it's the Egyptian Embassy/MFA Cairo. The current version of the 2014 Digital Digest by Mike Chace-Ortiz (Spectrum Monitor editor) has an extensive description of this network. Also see the Utility DXers Forum on Groups.io for current frequency information
