 Making contact with another "Ham", whether in the next village or on the other side of the world, on equipment you have built yourself, either from discreet components or from a kit of parts is one of the most enjoyable aspects of our hobby. This is  "Home Brewing".  

There  are a number of sources of circuit diagrams of everything from simple pieces of test equipment to complex multi-band multi- mode transceivers.

A number of companies producing kits for the Amateur market have come and gone over the years, Heathkit and Wood and Douglas to name but two. 

There are still a few companies who produce kits of various degrees of complexity for anyone who wants to "have a go" but prefers to use a proven design with ready made printed circuit boards and a kit of all the necessary components.

 

One such company is Cumbria Designs, their WEB Site can be found at http://www.cumbriadesigns.co.uk/

Below is a list of kits produced by Walford Electronics.
