11175 USB is Military freq. that broadcast the "sky king sky king do not answer" followed by alpha numerical strings. They are similar to a EAM but most are not true EAMs.
I monitor these daily and the content was too colorful to share here.
I reported it on IRC #wunclub at 22:44 and off at 22:54 according to the logs, it sounded like Offutt AFB to me.
The language was colorful but not as bad as many service members I have heard in my life. At least the subject matter was not about the base commander or something.
True on the language.......I was thinking McClellan though. I hope those guys don't get in too much heat over this one. I was trying to think of a way to call McC and let em know. Got a son out at Benning now (19th Infantry) Those guys have enough on their mind. Lol
