Yes, BUT -- that 24VDC to 12VDC converter is almost certainly some sort of switching power supply, and you will need to carefully search to find one that is not a source of RF noise.. AND the conductors are going to need to be pretty large, because they're carrying a 10A load (at 24V) just to run your 100W rig. Multiply that current (and copper) by about 9X if you also want to run a 500W amp. And the only one I know of that runs on 13.8V is the Ten Tec Hercules II, a very nice amp that's been out of production for about 20 years. 73, Jim 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
