      Thanks, it was fun to hear such young people watching my channel.
      I'll be coming up with a lot of interesting videos soon.
      Takk, det var artig å høre at så unge folk ser på min kanal.
      Jeg kommer med mye interessante videoer snart.

    Thank you for video. Just read John Le Carre's The Looking Glass War which features a B2 suitcase set which is described exactly like the real thing as seen here. Great to see one in action and explained.

    Thank you Helge. Always interesting. Your suitcase has THREE LOCKS! All the B2 suitcase ones did. The radio was so heavy that reinforced fastenings were needed. Have you ever seen a normal suitcase with three locks? No, nobody else had, either. That's why carrying this radio in public, around sharp-eyed Germans [*] was suicidal. You would have thought that the British would have realised this.
    [*] German 'Radio Security', aka Signals Counterintelligence, was the remit of technicians of the civilian/paramilitary Ordnungspolizei - not, as many might think, the Gestapo. When these 'Orpo' needed armed backup to arrest Resistance radio operators (and the Resistants were often desperate enough to shoot it out), they were reinforced by regular Wehrmacht 'garrison troops', not the SS.

    The B2 set is a two tube 'Crystal Oscillator-Power Amplifier' transmitter - like its smaller brother the A2 set and like the British airborne forces WS76 and like the later American AN/GRC-109. This type of Tx has the advantage of simplicity and can also operate both on the Xstal fundamental and the next harmonic frequency. The drawback is that the Xstal is worked very hard and without care can be easily and permanently damaged. At Arnhem, 1944, the British 1st Airborne Division blew up its WS76 'Day Xstal' on the first day (although replacements were successfully air- dropped on Day 3). 'Night Xstal' continued to operate normally. on the lower frequencies. The Arnhem Correspondents' BBC Press Liaison WS76 set, perhaps more carefully operated, worked well at all times and carried the bulk of 1st Airborne Div's communications with British 1st Airborne Corps Rear HQ at Moor Park, London - a distance of around 400km (215 mi). The American AN/GRC-109 is a low power COPA set first popular with US Special Forces in Vietnam (and later as first line combat comms for US infantry generally in Indochina). How interesting that WW2 era tech should prove superior to 1960's tech!

    Many thanks Helge! Absolutely fascinating! I have one of the original Morse keys for use with the B2. It must have been very difficult to send good c.w. with such a short leverage key. I’ve never owned a complete B2 myself but I did have a B2 receiver over 50 years ago. I bought it at a club junk sale at the Southampton club. It was a remarkably good receiver and I found that the regenerative i.f. was very effective for telegraphy work. I enjoy your videos, please keep producing them!

    These radios are described in some detail with beautiful line drawings in "Clandestine Operations" by Pierre Lorain.

  • @alastairbarkley6572
    @alastairbarkley6572 7 місяців тому +1

    Oslo to London is about 1200km (700mi). With the B2s 20 watts CW, you wouldn't expect reliable QSOs - which is why operators had 'skeds' (times at which and frequencies on which London would listen for a particular Network radio op). If contact was not established, the network op would most likely have to move location and try again at the next 'sked'. Using radio sets of greater output power might increase the chance of making contact but was impractical for most covert Resistance operations. Having to change QTH and retry obviously increased the risk of detection which is why the communication schedule of individual espionage Networks was a closely guarded, 'Chinese Wall' secret. In the hands of the Nazis, such knowledge would almost guarantee the capture of the Op and, most likely, other Network members.

    I'd love to see videos about the procedures and techniques. When did these operators get on? What frequencies did they use? What procedures did they use to establish contact? That sort of thing.

    • @alastairbarkley6572
      @alastairbarkley6572 7 місяців тому

      As someone else has commented, John Le Carre's book "The Looking Glass War" gives a remarkably detailed account of how to operate on of these sets as a clandestine agent. Not just the technical aspects of the radio but operating procedures, frequency selection, crypto protocols etc. If you're really interested, grab a copy.

    I have a student who is participating in the National History Day competition. She is doing her research on the Enigma. In our research we came across your website and are interested in your photos documenting the history of the enigma. She would like to use these photos in her research paper if you could at all provide a bit more background information. Where did the photos originate from? Do you know the original source? We look forward to hearing from you.

    Hello! I am writing a piece of music about Marconi in Chelmsford, Essex. I was wondering - would you mind if I recorded and used some of the sounds of the radio from this video? Thank you!
