About My Notebook

radioHere are some notes about the homebrewed equipment that I have made and used over the years. It has all been constructed using the well known KISS approach, Keep It Simple and Stupid. No bells and whistles here, essential features only.
I make no great claims for any of it, (some pictures click to enlarge, if you do you will see why I make no claims) other than to say that building it and using it on the air has given me the opportunity to occasionally work some DX, and no small degree of amazement that it has worked at all!radio
I hope that in a small way, this website might encourage more home construction, something that can only be good for the hobby of Amateur Radio. After all, if I can do it, so can you, and very likely with better results!
