Hi ELF,
Thanks for your reply and I can confirm that.
Back in the good old days of STCICS you'd hear Architect with weather reports on the hour and airfield colour states on the half hour, and at other times aircraft on long distance flights (C130 Herc's with the callsign ASCOT and four digits). General calls were made to the callsign CELEBRITY e.g. "Celebrity celebrity this is Architect Architect. Airfield colour states at zero nine zero zero zulu....".
When it all changed to TASCOMM in the middle of 2006, Architect fell silent and to my knowledge has never been heard since, unless you or anyone else knows different? I was fairly sure HF had been pretty much abandoned, however the test transmission I heard shows that the infrastructure is still there at least and I that is quite significant.
Some monitors have reported hearing ALE bursts with callsign XSS (Forest Moor NCS) but not regular soundings as you hear on the DHFCS ALE net.
Happy New year
Alan
