In the late 90s I was working in Coventry and we had some inductors wound by Repanco or Repanco-Bartlett as they were by then. We went to visit Repanco on Foleshill Road to discuss some aspects of the coil design. As we were walking through the factory I noticed a data sheet just lying around for the DRR2. I wish I'd asked if I could have had a copy.
I have built a number of crystal sets using the DRR2. One using 2 coils is incredibly selective managing to separate Talk Sport, Radio 5 Live, and Absolute Radio from the Moorside edge transmitter which I can see from my house 8 miles away. A single DRR2 crystal set brings in Talk sport and Absolute radio simultaneously with the tuning control appearing to act as a balance control varying the volume between the 2 stations. Radio 5 live not even audible on that set.
