Then when I retired from ATC at Farnborough and started FISOing from Fairoaks less than 2 weeks later, a lot of pilots found it confusing hearing my voice saying they thought they had the wrong frequency selected!
I must have a fairly distinctive R/T voice (hopefully so for the right reasons). I changed jobs after a period of three years and again after another five but remained based in the same local area as a certain major airport. Both times I changed jobs I took great care to get my "new" callsign correct so not to embarrass myself, especially as my original callsign was a police one. Even so, when I called that certain "local" ATC unit they sometimes responded using my old one, which got me confused me, too!
