This is the manual that accompanied the Heathkit EK-2 radio receiver kit, and comprises a basic instructional course on radio fundamentals.
Topics covered include, of course, assembly and alignment of the EK-2, and theory of radio detection, filtering, and reception in a superheterodyne receiver.
Heathkit Corporation has demanded their manuals be taken down from BAMA, so I'm trying to get them all out there again via torrents! If you have scans of manuals or paper manuals to lend me for scanning, please post a note or files at http://dropio.com/heathkit
Thanks, and let's keep those tubes glowing!
