This video is part of the Old Book Teardown feature of my video blog.

In this video I tear down Frequency Modulation: An Introduction To The Fundamental Principles by A. W. Keen, M.I.R.E., A.M.I.E.E. This book was published in London in 1958. The book comprises 274 pages and is chock full of schematics with old vacuum tubes.

Some items of note from the book:

• Armstrong phase modulator by Edwin Howard Armstrong
• Louis Alan Hazeltine was associated with the FreModyne
• A Klystron is a particular type of vacuum tube
• A Phasitron is a type of Beam deflection tube
• RCA is the Radio Corporation of America
• You can read about superregeneration on the Regenerative circuit page
• A superhet is a type of radio receiver
