The role of home construction, for many years, the percentage of home construction within the hobby has been fall-ing and, for many amateurs, is now approaching zero. While in some ways regrettable, it seems an inevitable consequence of modern technology. As noted several decades ago, there have always been only two really compelling reasons - at least as far as the majority of us are concerned - for building ratherthan buying. The first is when one cannot buy exactly what one wants (and for many years this covered practically the whole gamut of HF and VHF equipment). The second is when one believes that it is possible to build the item more cheaply than the market price, to such an extent that this outweighs the nagging fear that one may never get it to work as well as a factory unit of comparable specification. A possible third is the enormous personal satisfaction to be gained from 'rolling your own', whether or not the resulting equipment is of equivalent performance to a factory-built unit.
