D4OH 1948 Germany

The early post-war occupation forces in Germany had prefixes -
D2 for the U.K., D4 for the U.S.A. and D5 for France.

This card from August 1948 is from D4OH (operator F3OH ).
It gives a French address in Poitiers, looks very genuine, and the printer was "Imprimerie Speciale des Transmissions - Berlin"
But why not a D5 for a French station and operator? G4UZN

"D4OH" was the official callsign, used by Colonel André CHEVET, chief of the French military transmission in Berlin (1946/1948).
His french call was F3OH, in Poitiers (86).
He never used a D5 call, why ???? but he was really licenced. F2VX

The call is unusual, and not listed in the 1948 call-book, as so many D4xxx, D2xx, and D5xx for the occupation zones in Germany from 1946 to 1948. A 2 letter suffix for such a D4 call does not fit into the known pattern. British stations in Berlin used their regular D2xx calls (at least according to the mentioned call-book), and the French in their area in Berlin would probably have used a D5xx call with a consecutive suffix. D5BJ, for example, operated from Berlin. Norbert Maibaum

My guess is that D4OH is a made up "undercover" callsign. K8CX
