There are plenty of threads here where Fellers is mentioned, nay discussed. On a quick skim none refer to how his coded signals were discovered.

Andreas, I do acknowledge that it is one account from a German "insider" working with the UK & USA post-war. Perhaps Flicke's story is a "smokescreen". Anyway, a mild diversion and so back to tasks at home and then homework.
Gershom Gorenberg has laid out what disclosed the fact that the Black Code had been broken. It was carelessness because (again) the Germans believed Enigma was unbreakable, not some play on the German radio: The Espionage That Won — and Almost Lost — the War at El Alamein Keep in mind that in the 1950s, Fricke would either not have known or not have been allowed to disclose if he had known, that Enigma had been compromised. All the best Andreas
