There are switching power supplies and there are switching power supplies. Not all are created equal. If you go to an electrical supply store to buy a transformer to run 12V lighting, they will sell you a switching power supply that is a holy terror. They call it an electronic transformer. Ask them for a real transformer and you get a blank stare. Most wall warts that provide DC power for battery charging, or to run consumer electronics of all sorts are switching power supplies. Many of them are quite noisy. 73, Jim Brown K9YC ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:[email protected] This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html
