Construction and workshop practice
There are many reasons why radio enthusiasts might choose to build at least some of their own equipment. Even in a world where commercially made equipment is readily available, there are some advantages to rolling your own. The most obvious advantage is the potential to save a lot of money by building your own rig instead of buying off-the-shelf equipment. It is possible to build useful radio equipment using components that were recovered from scrap equipment. Surplus components can often be bought at very reasonable prices from specialist suppliers or from Internet auction sites. A well-stocked junk-box is a very valuable asset to the radio constructor.
