My father Tony was for most of his life an enthusiastic ham radio operator. That's him above, in his "shack" from 1976 on, which was my old room. Part of the protocol of the hobby was the postal confirmation of on air contact in the form of "QSL" (confrimed signal) postcards. I inherited a shoebox full of them, cherry picked from perhaps four times as many. Many of the most interesting ones (including a large number from the Soviet Union) come from the years 1968 to 72 when we lived in Scotland.
