Radio! Radio! is a book by Jonathan Hill.
Might have helped if I put the exclamation marks in
https://www.amazon.co.uk/Radio-Jonat.../dp/0951144871
Second hand copies can sometimes be had or maybe you can get a copy from the library?
It's a fantastic resource.
Web site is ongoing what model scope is it?
I am concentrating on domestic radio but will be putting up a test equipment section.
Cheers
