Amateur Radio Equipment Manuals and Circuit Diagrams from The Cornish Radio Amateur Club G4CRC

As and when I come across manuals on the web I will upload them to the site for members to download.
If what you are seeking is not there don’t complain I will just not have found it.


To use any radio for voice transmission you need a microphone, of course, here is a document providing wiring diagrams for a whole host of different radio types. Many thanks to the author for his tireless dedication to the topic and for presenting the information in suce an understandable format. As we all say, a photo speaks a thousand words.
