I thought that's what I said ... if I didn't, I was wrong ... as close to the power supply as possible. Many present era power supplies have over-current protection built in, and in those cases, I wouldn't use an external fuse at all, just more places for voltage drops. If you're on a battery [even if float charged], you really must fuse as close to the battery as possible, high capacity batteries can deliver an incredible amount of energy very very quickly. If you're in a vehicle, both + and - leads should be fused. The + lead for the obvious, the - lead in case the negative battery connection becomes faulty. In that case, the starting current would find its way back to the battery through the radio neg lead. 73, Fred K6DGW - Northern California Contest Club - CU in the 2012 Cal QSO Party 6-7 Oct 2012 - www.cqp.org ______________________________________________________________ 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
