If it were my radio, I would add one or two silicon diodes in series with the positive lead to reduce the voltage to about 14 volts. For a 10W K3, I'd guess that 5A diodes would be just fine. If it's a laptop supply, I would also be concerned about RF noise that it might produce. 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
