[UK-CONTEST] Aircraft reflections -more

[Giles Herbert]

There were two parts to the article which was called "A little flutter at VHF" by Paul Sollom G3BGL.  I cannot remember the dates of this but as you say it was in the middle(?) sixties.  By the way, it was the Lille Band three Vision carrier that was the signal source which was constantly audible at his QTH near Newbury.
