Morning Bryan and all, > That is the main calling freq for the US air force "Global Command and > control System" Actually Bryan things have changed a bunch in the last few years. The system you referred to (aka GCCS) has gone through several name changes over the last 15 years and is now called the HF-GCS. Also the freqs have changed quite a bit. The primary and most widely used freqs are now down to (all USB mode): 4724.0 6739.0 8992.0 11175.0 13200.0 15016.0 and 6712.0 kHz (Croughton AB UK only) You can get detailed information on this system on my personal blog at the following address http://mt-milcom.blogspot.com/2006/05/joint-chiefs-of-staff-hf-gcs-network.html > Would it be possible that E10 had a transmission on 11175Khz (or a > frequency > around it) at 17:20z today? Now on to the message question posed by Martin. There are two types of messages broadcast on the US DoD HF-GCS network. One is called a Foxtrot message (the highest priority message they have). It resembles the following format: "Skyking, Skyking do not answer. authentication "ABC" (3-ltrs), time 1643 (in zulu). I won't go into what these messages are used for since some of it is still under research and I haven't confirmed some details of their usage. I hope to cover it in detail in a future Monitoring Times very soon. The bulk of the messages transmitted on this network and the one you probably heard are called EAM (Emergency Action Messages). There have been a lot written about these messages over the years on the net, and most of it is unfortunately wrong. Several years ago in my column in Monitoring Times I covered what these transmissions were being used for. It came from official sources and has since been posted to the internet. Now in my December 2009 MT Milcom column, I covered the latest information on EAM broadcasts (all of it was based on official sources in the public domain). You can get more about that including some new additional details again on my blog at http://mt-milcom.blogspot.com/2009/12/what-is-eam.html. In addition to the frequencies mentioned above for the HF-GCS, DoD also transmits EAMs on discrete HF freqs: This usually happens when there is a big USSTRATCOM exercise underway. Recent activity has been heard on the following freqs (mode is USB): 3160.0 4515.0 4720.5 4739.0 4774.0 4848.0 4937.0 4982.0 5251.0 5680.0 6512.0 6666.0 6686.0 6720.0 6724.0 6761.0 6778.0 6807.0 6833.0 6883.0 6903.0 6988.0 7332.0 7498.0 7501.0 7589.0 7661.0 7703.0 7705.0 8008.0 8020.0 8026.0 8035.0 8971.0 8996.0 9007.0 9010.0 9016.0 9036.0 9283.0 10160.0 10183.0 10204.0 10281.0 10510.5 10515.5 10805.0 10994.0 11052.0 11053.0 11055.0 11057.0 11059.0 11187.0 11220.0 11252.0 11255.0 11271.0 11674.0 12010.0 13212.0 13812.0 13911.0 13960.0 14698.0 15011.0 15038.0 15049.0 15097.0 15962.0 16117.0 17973.0 19665.0 kHz There are also special frequencies known as EAM restoral discretes that are used much more frequently. Some of these have been IDed and are as follows (again USB mode): TACAMO Pacific 6697.0 8776.0 11244.0 13155.0 Worldwide 8968.0 8992.0 9002.6 11267.0 For Martin and all, you will find a lot more information on my Milcom Monitoring Post blog and the best pat is it is "free." ;-))) 73 and good hunting de Larry Larry Van Horn, N5FPW Brasstown, NC USA MT Assistant/Review/Technical Editor Milcom/What's New/First Look Columnist Milcom Monitoring Post at http://mt-milcom.blogspot.com/ ----- Original Message ----- From: "w0ese" <w0...@embarqmail.com> To: "Shortwave Spy Numbers Stations" <spooks@mailman.qth.net> Sent: Sunday, January 03, 2010 1:51 PM Subject: Re: [Spooks] E10 (?) 01/03/2010 11175khz Am -- 17:20z > Visit http://mailman.qth.net/mailman/listinfo/spooks to unsubscribe from > this list > > > That is the main calling freq for the US air force "Global Command and > control System" you will hear numbers groups from YLs and OMs. You may > also catch an occasional phone patch, radio checks, etc. Other freq used > for GCCS are: > > 4724 > 6712 > 6729 > 6739 > 8968 > 8992 > 10780 > 11220 > 13200 > 15016 > 17976 > 15010 > > enjoy, > > w0ese > > ----- Original Message ----- > From: "Martin G Choquette" <macta...@gmail.com> > To: "Shortwave Spy Numbers Stations" <spooks@mailman.qth.net> > Sent: Sunday, January 3, 2010 11:46:22 AM GMT -06:00 US/Canada Central > Subject: [Spooks] E10 (?) 01/03/2010 11175khz Am -- 17:20z > > Visit http://mailman.qth.net/mailman/listinfo/spooks to unsubscribe from > this list > > Hello all, > > Would it be possible that E10 had a transmission on 11175Khz (or a > frequency > around it) at 17:20z today? > > I unfortunately do not have a recording and got the very end of it, was on > scan mode when I intercepted it. > > It was the usual lady voice with phonetic alphabet ("Alpha, Bravo... end > of > transmission...").
