The net was very busy throughout the Egyptian night on 6568khz 6666khz 5531khz. Apparently training. At least 11 callsigns, including ANTHONY. Lots of STANAG 4197 and ?HFDL? probably all empty. Nothing now on their day freqs or anywhere else. So here is what I have on them.
Primary Day
12850
Primary Night
5531
and they work their way up and down when the atmospherics change through
6568 6666 8888 10519 always usb.

I used to get them passing plain text observations of ships in the Med and Red Sea including LAT, LONG, Az Range, Speed, Track #, Time.
Even got a weather report once. That was when it was fun. Now it's just callsigns and signals that may be idle all the time. Maybe even the plain text was bogus.
So it is Egyptian Navy, coastal observation if they really are observing anything. Use the kiwisdr to get a rx in Italy or Greece. Utwente worked last night.
Move the thread to another forum, change the title, and let old soldiers fade away...

Just to put a cap on this, it appears the data bursts are a MIL-STD-188-110 type, not HFDL, per the UDXF....Mike

It isn't HFDL at all - it's a modified MIL-STD-188-110A/B data stream, and it's being investigated on the UDXF reflector at groups.io

Thought to be Egyptian in origin...Mike
