The K3 can safely be set to its maximum QRP/QRO power levels. If any operating limit is exceeded (temperature, voltage, current drain, SWR, reflected power, etc.), power will automatically be rolled back.
While this protects the radio 99.9% of the time, things can happen -- lightning, ESD, component failure, Acts of God, pet disasters, 8-year-old-boys, etc. In the present case, some quick resistance or voltage checks might reveal what's going on. Check the Troubleshooting section of the manual, which is pretty extensive and can help you solve most problems. If that doesn't do it, call customer support. 73, Wayne N6KR ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html
