G3VGR Amateur Radio Projects      

I am a Radio Amateur, not an Amateur Radio Operator.  Ham Radio is a technical hobby and I enjoy experimenting and building equipment, more so than actually operating. Whilst it is not really viable for most hams to build a complex transceiver to compete with a FT1000MP, station accessories are another matter. Most simple accessories are very expensive, considering the parts count involved and can be easily built at home. Whenever I go to hamfests, I'm amused to see people paying high prices for items such as a readymade G5RV antenna, as if it was a wonderous technological product.

I became interested in QRP because it is very easy to build simple transceivers and useful station accessories both cheaply and quickly. However, one discovers that it's all too easy to end up with too many power supplies and ATUs!
