The only other use of alpha numerics was an experiment in 1982, all letters of the alphabet were used except A and D.
1st letter was B then a 4 denoting a 1-11 or a 6 denoting a 748. So 24 letters used. Eg DA001 B6BB, DA024 B6BZ. DA025 C6BB, DA048 C6CZ.
These were the only examples of alpha numerics used by Dan
Sorry,a bit late,but it's the first time I've looked at this thread.There was a trial of alpha-numerics in the very late 80s,or early 90s.I didn't arrive at LATCC until 1988,and I can remember an occasion when on the Pole Hill sector,I had a Dan Air,and a Midland on the frequency at the same time,both of which had the same Alpha-numeric suffix to their call sign,and all three of us were becoming confused at times.They were something like BD498AB,and DA498AB.Thankfully the trial didn't last long !
