Yes, I think there was a radical change in callsigns in the late 90s. I know the Jag OCU used Tartan as a formation callsign in the 80s. At Coningsby in the 90s we were asked to register sqn and station callsigns. My boss, OC Ops was cheeky and registered Typhoon as we were slated to have the Typhoon OCU. He was surprised when it was approved.
I think one of 29s was Triplex.
