The "companion" to the Screwdriver Experts Guide, this book studies the PLL and how it works.
The book goes into some depth about PLL circuitry and gives details on all the popular PLLs and how to modify them to obtain extra channels.
This book is over 10 years old and so will not cover some of the latest PLLs (although most radios now use microprocessors instead of the standard PLL).
