Any power supply that has a VFO knob built in means they either don't know how to get harmonics down to the proper level or don't want to spend a few bucks on components, so they took the cheap way out. I have several switching supplies and can't hear any of them anywhere unless I run an antenna right in the room. ______________________________________________________________ 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
