A=20 can of worms.
Some would say G9*** is a research and development licenc= e and=20 no G9's are Amateur calls.
"G9 Plus two or three letters have bee= n=20 issued to research organisations"
However
"I us= ed a=20 G9 plus two callsign for research activities"
"About 5 ye= ars=20 ago, I obtained GW9T for Wrexham ARS."
Quotes are from=20 MW1LCR

So there is a bit of background on G9 calls. What I think An= dy was=20 doing was telling the story without using a normal Amateur callsign which= may=20 have been issued ie not an actual person, for the illustration.

Or= does=20 Andy use G9BOF at work, I don't know.
