Make sure to see the several readers' versions. Also see the new Sferics Detector. The following circuit is an improved version of my original Lightning Detector designed to run on a 5 volt supply. The new circuit features a superior RF section with a single. In a previous post: Versatile Dual Power Supply Printed Circuit Board I described a dual power supply design that I hoped would fulfil 90% of my needs. To this end, it was very successful, and several have been built and installed in various pieces of equipment. These have been mostly of the ‘fixed’ type of supply, and for types using the LM317/LM337 adjustment of the two presets has not. In the mid 1970s large numbers of small FM transmitters, operating in the FM radio broadcast band (88-108 MHz) appeared on the market.
