In post #11 I mentioned info that I got from the CBC website, that is no longer online, that the Type B Mk.2 suitcase radio had a range of just over 500 miles.
BTW: In searching Wikipedia regarding the Dieppe Raid I found an interesting item about the top secret German Freya radar system mentioned in last night's show:
"One of the objectives of the Dieppe Raid was to discover the importance and performance capability of a German radar station on the cliff-top to the east of the town of Pourville. To achieve this, RAF Flight Sergeant Jack Nissenthall, a radar specialist, was attached to the South Saskatchewan Regiment. He was to attempt to enter the radar station and learn its secrets, accompanied by a small unit of 11 men of the Saskatchewans as bodyguards. Nissenthall volunteered for the mission fully aware that, due to the highly sensitive nature of his knowledge of Allied radar technology, his Saskatchewan bodyguard unit were under orders to kill him if necessary to prevent him being captured. He also carried a cyanide pill as a last resort."
So, once again the programme used an actual wartime event as a storyline in X Company.
