F7AP 1952 France
F7 callsigns were issued to ham operators belonging to NATO forces that operated in France between the end of WWII and middle 1964.
I found my old call F7AY in your QSL Gallery! I received the call in late 1951 and used it until I left in December 1952. F7AP and myself kept the rig going quite a bit during this period. Here is F7AP for your collection.
