Harry Mills, K4HU, passed away recently. Harry was 100 years old and was active on the ham bands right up until the end. National Public Radio featured Harry and his ham station in an "All Things Considered" segment about early radio. It came out in 2001. I don't know how I missed this one -- it is really great. Have a listen: NPR program on KDKA, K4HU

It appears "L2" is a fixed regen coil and that the two "L" coils are wound
counter to "L1"?
