In years gone by, thermionic valves were the staple diet of the Ham Radio enthusiast. You still see lots of them for sale at Radio Rallies throughout the country! It was not until the 1950’s and moreso the 1960’s that transistorised solid-state equipment began to become commonplace. We all probably remember our first examples of broadcast transistor radios – the ones we nicknamed “trannies”!

And while valves are still the main drivers in high power linear amplifiers for example, there has been a resurgence of interest in homebrew valve technology in recent years. Even kits have become available for beginners to make QRP transmitters for example.

Valve technology however can be a bit of a mystery to many of us, so this Tuesday night at Wythall Radio Club, why not come along and learn a bit more about them?

Barry M0DGQ is a designer and builder of radio equipment using valves and will be presenting a talk called “A Beginner’s Guide to Valves”. It is bound to be an interesting evening and promises to enthuse many of us into having a go at building something using valve technology.

Can’t wait!
