Monday 21st September 1942

Instruments exam today. We all passed, I think. As soon as it was over we rushed into our tent and began eagerly arguing.... “He said, “How many contacts are there on the DV?” and I said “Three, on the key...”” “Wrong, Bob!” “Am I buggery! Three!” “No, there's two...” “Yeah, one brings in the 20,000 ohms resistance...” “That's so the anti-sidetone...” “But what about that contact behind the key, Leonard?” “Not a contact, it's a stop.” “No!” “Yes!!”

And so on.
