I am an EE student at Oklahoma State (Formerly Oklahoma A&M)–the school where the designer of the WLW [Super Power receiver], Amyle Richards, got his BSEE in 1927.

[Richards] wrote and submitted a masters thesis on the design of this radio, which earned him a PhD!).

I found a picture of him in the Engineering South building and found him in the 1927 yearbook in the library.

Anyway, the archive department located his paper on the WLW and is scanning it for me.

Many thanks to Larry for doing the research and sharing a scanned copy of Dr. Richards’ thesis about this Crosley benchmark receiver!

    In 1936 you could buy a Ford auto for $650. You could buy a 5 room and pre fab house from Sears for a little over $1400. The Colossus in today’s money would be just shy of $27,000. One was being sold on eBay in December for $166,000, you pick up. I’m waiting for the price to come down to something without zeros.

    Great to read some real electronics terminology instead of all your modern DSP/SDR mumbo-jumbo!!! (but keep it coming!)

    A wonderful article and technical description a la my childhood days. Thank you Larry for showing it to us and Thomas for posting it.

    Regards

    I only glanced at it now, but that should be very interesting reading. It’s an odd time, since radio was still “primitive”, but this was “cutting edge”. Just a few a few years before, there were the famous articles in QST by James Lamb about receiver design, a big leap forward. That brought the concept of crystal filters forward, and then they were appearing in commercial receivers, almost concurrently with this receiver.

    This thesis is probably equivalent to reading about upconversion and other new techniques in the early seventies, neat things that were the future. Things that existed, but weren’t “for the rest of us” until it could be made cheaper. You could sort of see the future, but the future was different when it came at affordable prices.

    Think of reading this as if it was 1939, not with the hindsight of decades later.

      How much was it priced at in those days? That must have been an upscale buy considering it’s size. What would it be in today’s dollars?
