NATO Psychological Operations (PsyOps) transmissions
This is an example of a NATO Psychological Operations (Psyops) transmission directed at Libyan forces under United Nations Security Council Resolution 1973 and Operation Unified Protector. Recorded on the frequency of 10125 kHz, USB mode, on June 26, 2011, at 1400 UTC.
These transmissions occur on past known usage Libyan military frequencies and start at the top and bottom of the hours, and often repeat the same message three times in a row. The source of these transmissions might possibly be the Hercules EC-130J "Commando Solo" aircraft. There have been several different format messages sent during the operations thus far.
More of the same as above.
There are quite a bit more videos with NATO Psychological Operations (PsyOps) transmissions on YouTube.
