Any decent supply that regulates to about 13VDC will work well provided that it is not electrically noisy. I've used Astron linear supplies, and a compact PowerWerx unit rated for 20A. The latter is switcher, but I haven't found any electrical noise. For many years, all of the 12V rigs I've owned, and all of the 12V accessories on my operating desk, have been powered by a big Costco deep cycle battery that is float-charged by an el-cheapo regulated 10A switching supply that I bought for $10 at a hamfest about ten years ago. That switcher was REAL noisy, but I was able to tame it with a few capacitors and chokes on both AC and DC wiring. 10A is plenty to keep up with even the most serious contesting. 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
