\nThomas M. Alldread, VA7TA, describes his wide dynamic range field strength meter<\/p>\n
\nTony Preedy, G3LNP, shows us how to achieve the enhanced performance of a high 7MHz antenna at a lower height using a design by radio astronomer W8JK<\/p>\n
\nJonathan Hare, G1EXG, gives us more 3D printing hints and tips, following on from his previous RadCom<\/em> article<\/p>\n
\nRubens R. Fernandes, VK5FE, describes how to add a tracking generator to his SA3000 spectrum analyser<\/p>\n
\nMark R. StJ. Foreman, G7LSZ, describes using op-amps and SPICE simulation to model a water-driven analogue computer from the late 1940s<\/p>\n","protected":false},"excerpt":{"rendered":"
