I haven't observed any RFI from the Morningstar Prostar but then my small solar setup isn't close to any antennas. I'll give that a try and let you know what I find.

I'd be willing to bet it varies widely from one regulator family to another. Another critical point -- current drawn from the panels and fed to the battery is pulsed DC, so should be viewed DC 100% modulated by DC square waves. ALL wiring in the charge path must be twisted pair to minimize radiation from it to nearby antennas. 73, Jim K9YC ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html Message delivered to n6...@outlook.com ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html Message delivered to arch...@mail-archive.com
