AN/CRN-4 beacon used in Bastogne — 8 Comments

  1. You need to read the book about Jack McNeice called the Dirty Thirteen. I haven’t finished the book yet but they do refer to the CRN-4. It is a most interesting book I have read about WWII so far.

      • Jake McNiece used the CRN-4 sets in Bastogne to resupply the 101st airborne. In his book, it details the events. In further research I have discovered that without the resupply the German blitzkrieg would have been a success. The CRN-4 sets were classified for many years after the war, so it’s hard to find accounts of their usage from the time.

        • Thank you for sharing this Jack! So this is more evidence to support the CRN-4 was used during the war. I wonder if anyone knows of an actual (complete) set still in existence?

  2. Hi Wouter,

    Do you perhaps have pictures of the CRN-4 beacon? I could only find a very vague photo which does not look very reliable. But I can imagine that your manual contains good pictures and/or diagrams, right?

    Thanks a lot!

    Note: To my knowledge the left instrument in your photo is not a BUPS beacon, since that is a lot larger and looks different, I can send you photos if you want. The instrument here is just a telescopic antenna with bag, which unfortunately is not that rare.

    • Hello Jeroen, I have added a picture to the post, so you can see from the antenna that the CRN-4 was a completely different set-up from the PPN-1 beacon. You can’t see it in this photo, but the beacon itself was split up into 2 padded bags + bags for the antennas. I have found 2 mentions of the CRN-4 in books, but no period photographs other than the ones I have in the manual. I shared the manual with guys who were going to make a reproduction of the beacon and the bags, but this never happened. I think it requires too much special skills and rare parts to make a convincing replica.

    • Thanks for sharing this link Alan. Very interesting. So, apparently this is what they called the ‘BUPS’ and it was already available in the summer of 1944. It was to be followed up the ‘BUPX’ (X for X-band), but no details on that in this video.
