TAH Instanbul beacon heard just above the noise floor. Surprised I stumbled on to it and heard it!

Its just "free channel" marker. Some other coastal maritime stations send them. But sometimes on this freq station send weather information in mode SITOR-B and provide telex service for ships in mode SITOR-A. You can receive and decode  ship to coastal station communication. But on modern ships hf antennas not so good and hf transmitter power only 250 watts, so i can decode only coastal stations answers for ship station in SITOR-A
