Someone had broken the Japanese code. The Americans had broken it. They had their own Morse Code; different sounds for different letters. We learned to record that.
When I was in… My time in [RCAF Station] Winnipeg [Manitoba]... and somebody came to us and said, "we want some volunteers for a secret job, can’t tell you what it’s about, and you won’t be able to talk about it either." So a bunch of us said yes and they posted us to Trenton to Kingston, Ontario. We went to the army barracks in Kingston. We were there for another six months, I guess. Someone had broken the Japanese code [the American military's MAGIC cryptanalysis project]. The Americans had broken it. They [the Japanese] had their own Morse Code; different sounds for different letters. We learned to record that. That’s what we learned to do and we worked away at that. The Japanese had a different alphabet altogether. They had MA, ME, MI, MO, MU. They had a consonant and a vowel, and that was one series of sounds. We learned to record that. After we recorded, it was transmitted. I don’t know where to, but it was broken somewhere else. We didn’t know anything about that. We just recorded it. So from Kingston, we went to Trenton for a week or two and then we were posted to Victoria.
