SIGNALS اشارات

The Egyptian Navy sends two types of signals in HF. They are called MIL-STD-188-110A and STANAG 4197. But you will never hear them called that on air. They will call it وضع اثنين or mode two. They will call it احمد شكري or just شكري. MIL-STD-188-110A is sometimes called SIERRA, DATA, or HARRIS. STANAG 4197 is sometimes called مرك or MARK. We don't know if that is short for Marconi or something else. Harris is the company that makes the modem that encodes/decodes the signal. You may hear the operators reading the time off the clock by the second, to synch the modems we presume. The signals may also be referred to according to their content, such as محمود وادي for a position report, فارس احمد which we think could be FAX, تاجر نحاس which we think is تنظيم or تنسيق, and تاجر قمر for تقرير. You won't find software that will decode the signals but they are not completely useless. They are ideal for TDoA attempts. You will find examples of these signals on the Reports page of this website.
