Interesting stuff. I haven't seen this one before. Lots to read and digest. I have only done a brief look-through, but will read more later. Thanks Dood!

Yes he did know his stuff in fact I was using his entire AM collage radio 10 watt system for about 5 years before I sold the transmitter. I did not sell the AM tuner and just a few days ago with the help of the Dood and Boomer i was able to get the tuner hooked to a fox 20 watt transmitter.

No power out of the tuner but the signal goes out via ground wires. Did a few test this weekend with full power the range was close to 6 miles.
Great stuff.

Well, the book that I really want to get-out and scan .PDF, page, by page, is the 1979 version of Ernest Wilson's - Carrier-Current Broadcasting : The Wired, Wireless. That's how I modeled my AM Carrier-Current Stations after. Ernie, really knew his stuff as well. I wish that Kinkos was still around, since they were great for project like that. We'll see...

Save yourself the hassle of scanning it, heres a pdf

Also soon the internet Archive will have uploaded some 1940s IBS Technical Data Books available which details how to setup a carrier current system like the did it at colleges back then

Edit
I knew I had that book but couldnt remember where it came from. . His book in pdf linked above originates from https://steampoweredradio.com/manuals.html which has a wide selection of others

Thank you tybee!!!! Good find. Never found it on-line in the past. Good to know that it's out there now. Being 1979, everything radio-wise is still useful today, at the transmitter and Couplers end. Everything else, can have the 21 century touch. Hopefully, Steam Powered Radio will stay up there.
