Build By Homer L Davidson — Radio Receiver Projects You Can

Radio Receiver Projects You Can Build (ISBN 0-8306-4119-0) is out of print, but used copies are plentiful on AbeBooks, eBay, or your local hamfest's $1 bin. PDF versions also circulate in the DIY community (though we always recommend buying the original if you can find it).
