David,
thanks for the link, superb!
If it helps, I can't do any of these games either, in spite of 29 years as a NATS operational ATCO. In all that time, never ever saw a "sprite" on the radar.
Love your 'ident'. LIC 545 KHz, just south of the A38. A sad day when she was finally switched off.
P.S.
If it helps, 'PEDIG' is more or less the same position. Have a guess why it's called PEDIG.
