Topband: Perusing an old book - Construction of radio phone and telegraph receivers for beginners

[James Rodenkirch]

A neighbor was perusing some old books her father had saved - he was an electrical engineer - and found a 1922 edition of Construction of radio phone and telegraph receivers for beginners authored by M. B. Sleeper.

Started perusing it last night...what a hoot! All about designing rcvrs for the  200 meter band.

Latest edition is 2011 - https://www.amazon.com/Construction-Radio-Telegraph-Receivers-Beginners/dp/1247774619 -   so it's  hung around or some time....72 Jim Rodenkirch K9JWV
