I had the same problem originally. It was the power supply current limiting! Supposedly, a 25 amp supply, it would start limiting at about 18-20 amps. This dropped the voltage which would cause the radio to shut itself off. 73, Roger ______________________________________________________________ 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
