I have received a note via the UDXF with the following details:

It was a US STRATCOM SKYMASTER exercise with E-6 TACAMO aircraft sending EAM/FDM messages and taking four character messages from USAF bomber and tanker assets. DOOM is a B-52H from 2 BW Barksdale AFB. DOOM 71/72 were also rebroadcasting EAMs. There were a number of other aircraft passing messages including BUNT 31-34 which appeared to be KC-135R from 6 AMW at MacDill AFB as well as SUNUP 35/36 and CLEGG 98/99.
