Building Alfred P. Morgan's "A More Selective Crystal Receiver"


As I’ve been seeing a lot of new membership requests on my Facebook Crystal Radio DX group indicating that they wish to build a crystal receiver, I’ve been examining some simple inexpensive circuits that should work well for local reception and possibly even to hear some skywave DX signals.
Since I’ve always wanted to build Alfred P. Morgan’s ‘A More Selective Crystal Receiver’ from his second ‘Boy’s Book of Radio’ ever since first seeing it at around age 10, I chose this as a start.
How did it Morgan’s design work? Could it hear all of my 15 locals and separate them? Was it a DX machine?
I invite you to read about the whole process on my web page, just published today:
