16 November (UTC):

10420.0 XSS sounding at 0017, 0047, 2358.
14782.5 XSS sounding at 0044.

17 November (UTC):

14728.5 XSS sounding at 0025.
10193.5 XSS sounsing at 0029.

Other times and frequencies are no joy. The fact that the best signals seem to come in the late afternoon local time in November would tend to rule out the UK as a source. Perhaps XSS/ DHFCS/ TASCOMM is continuing to add transmitters as the network is built out and used by the UK military.

XSS Finally Heard in Western US!

XSS is the Automatic Link Establishment address (ID) for the probable control station of the UK's new Defence High-Frequency Communication System (DHFCS). The control location is Forest Moor, England, though remotes are possible. It has been heard widely in Europe and the eastern US, but not out here on the Left Coast.

Not until today (UTC date 15 November), anyway. Several ALE soundings have been received on 14728.5 kHz. Here's the PC-ALE output:
