This site includes pages that may be of interest to fellow radio amateurs. In particular the SSB Transmitter and Companion Receiver are modular and come with several circuits and board layouts that can be used in other projects. For easy "weekend" projects there is the PA0RDT active antenna, also there are 6m antennas that are easy to make in a home workshop and some ideas on HF vertical antennas too.
If you find the site useful, please send me an e-mail. Details can be found on my entry on QRZ.com
