Inside the Black Box of Short Wave Radio
You can be a person who likes to listen to radio and that is the real deal of why broadcast radio exists.
Growing in popularity are cable shows such as “How its made”, “Batteries not included” and other shows that tell you how things work and how things are made.
As a kid you may have been one of those folks who liked to take things apart to see how they worked. Parents sometimes did not like this. One of our friends who has a son of about 10 years old asked “What’s inside Diamond?”. Diamond was the family dog.
But now we are all adults and can take apart anything we want – but maybe not Diamond.
So what is inside the black box of shortwave radio?
We stumbled across a free ebook written by a retired Broadcast Engineer. This is an excellent book on what is inside a glowing tube shortwave radio from a detailed technical perspective.
We like this book for a couple of reasons.
First, there is considerable technical explanation in this book. It goes a long way to teach you about electronics – just what you need to know – to understand how all the component stages of a radio come together to get the RF off he “air” and into your ear.
Second, the book uses a real example – the RCA model 8Q2 Shortwave Radio. This radio represents the common technology of the “All American Five” design used in radios from 1930-1960. So this book is not a book on “theory” without practical application. In fact, the book is so detailed that just about every component in the radio is explained.
The tile of the book is The Vacuum Tube Shortwave Radio: Understanding and Troubleshooting.
