One thing I would suspect based on your symptoms is a weak battery. Since about 2003, I've run all of my 12V ham gear from a big Costco deep cycle battery that is float charged by a 10A supply that regulates to about 14.1 volts with the battery hanging on it. I've never experienced any issues with this, and the batteries last 3-4 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
