Hi all. Early into CQWW this weekend I was getting reports of extremely distorted audio from my K3s. Being mostly a CW (and 6m FT8) operator I wasn't sure what was going on. I figured it was RF, but it was happening at all power levels, from QRP to 100W, and QRO with my KPA-1500. Same (bad) audio, just stronger/weaker signals. All bands were equally bad.
I ended up going from the radio directly to the tower, physically bypassing the amp and tuner, and only running low power, with the same result. It sounded more like distorted audio than RF ingress. Some troubleshooting by Dave, WO2X, who is a Flex owner: He remoted in to his Flex a few miles away and noticed my garbled signal was absolutely dirty and wide, despite low mic gain and little or no compression. The audio sounded clean through the monitor, so it wasn't the audio chain. He's speculating I may have a blown FET in the PA stage. We put in a Flex 6500 temporarily and it seems to be running fine. Wondering if anybody here has had experience with this, and if so, what are my next steps? Thanks in advance. --------------------------------------------- 73 and Good DX Peter, W2IRT K3s S/N 10023 ______________________________________________________________ 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 Message delivered to [email protected]
