Interesting Intercept in ITU IM #313

Here on the Btown Monitoring Post I have written several times about the HF XSS ALE net. And in my previous post to this blog I mentioned that the new International Monitor #313 is now available from the ITU website. I just started reviewing this doc this morning and found an intercept on page 2 that immediately caught my eye.

G BALDOCK 3161.00 19 02 0733 0733 XSS 2K80E J7D 248 B MIL-188-141 ALE

Based on day/night propagation patterns(a 0733 local time intercept in England), the intercept above adds more credability that the mysterious XSS ALE net is a UK based network. Based on monitoring it is widely believed that ALE address "XSS" is the netcos for this HF net and if so then this is most likely a British HF net (some estimates say British Ministry of Defense).

More as it becomes available.

XSS ALE Net Continues to Mystify

Sam on the UDXF newsgroup this morning (2/8/2007) posted his latest round of intercepts on the infamous XSS HF ALE net. He even managed to observe a two way conversation between the XSS ALE Address (probable net control and dominate sounding station) and unid XKY ALE Address.

Some other ALE Addresses that Sam and others have logged include:
XAS / XBC / XDV / XFY / XGJ / XGP / XHK / XHZ / XKA / XKD / XKW / XKY / XJF / XJT / XJP / XJT / XJV / XLG

I should note that the ALE addresses above are static as they are being used over again over a long time period. Thanks Sam for your continued diligence in monitoring this mystery.

Here is the latest list of frequencies for this net: 2199.0 2217.4 3161.0 3227.4 3280.0 4166.4 4226.5 6243.0 6425.0 8108.5 8126.4 10360.0 10458.0 12057.5 12333.0 14510.0 16553.5 18405.0 20300.0 20965.0 kHz.

One theory about this net is that it may be associated with NATO in Europe, but there still is no definitive proof of this. If you have any insight, drop us a note at larryvanhorn @ monitoringtimes.com. I am interested in hearing from some of the readers of this blog.
