[06:30] Remarks on Knokke: awful sound in cinema; few links with locals; Belgians stealing fuel from PULTO pipeline; airfield at Knokke; RBK duties sorting out radio problems; RBK investigations into an infra-red detector; squadron duties chasing E-boat torpedo boats; RBK flying on testing flights, in Sea Otter and captured Bücker Jungmeister. [12:30] Story about visiting German radar installations around The Hague: photo reconnaissance; driver Norman Chambers; visit to Mammut radar; RBK informing R.V. Jones; use of reflected CH transmissions by German radar; very cooperative Germans; unpopularity of Canadian troops; anecdote about Norman Chambers and RBK being invited back to Belgium for commemorations, RBK using ham radio in 1944 to tell people in UK they were safe, awful Canadian music to dance to. [17:30] Remarks on: German and British Radar equipment compared; German system similar to H2S; powerful Neodymium magnets, which went unused in Radar; anecdote about seeing an Enigma machine; German's expecting to be on same side after the war; British expertise in electronic countermeasures, such as radio navigation beam jammed by RV Jones; German use of British IFF system as a bombing aid, WREN responsible for providing fake German communications to system, jamming methods; [23:45] impressions of German equipment, RBK interview by RV Jones and Robert Cockburn on return; story about RBK discovering Neville Chamberlain's early support for radar from Lord Home; RBK meeting with Robert Cockburn. [27:45] Further remarks on investigating German Radar: RBK stealing generator off a German car to repair his car; T-force pass; visiting large number of sites; Würzburg radar, Göring's high opinion of system, use of Doppler effect; return to TRE after VE-Day via RAF Warmwell; RBK visiting exhibition of German equipment with miss Jones, on approval of M V Wilkes, wire and tape recording equipment. [32:50] Story about installing ASV-XI equipment as a landing system on HMS Pretoria Castle in 1944: RBK borrowing a wire recorder from RAE Farnborough to record conversations during landing; EMI copying German tape recorder; RBK working in a Norwegian Martman-Moe from Admiralty Signals Establishment [ASE]; differences between ASE and TRE; anecdote about ASE almost being renamed Admiralty Radar and Signals Establishment.
