Was running the CQ WPX CW contest here on 20 meters after a normal transmit cycle, the radio unkeyed and immediately everything was very quiet. All of the signals dropped in strength by about 7 S Units.
I tried keying up again but this time I wasn't getting any power out and a high current warning from the radio. I dropped the power from 100W down to 12W. As soon as the relay kicked to switch to the LPA, the receive was working fine again. I'm getting the full ~10W out of the LPA. So... I pulled out the KPA3 and quickly noticed that D10 is blown. Other than just a normal diode failure, could there be any suspect external causes for this? I'm not very good at schematics. What is the purpose of this diode? 73 DE AB3LS ______________________________________________________________ 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
