I accidentally hooked up a bias tee (DC power injector) backwards, which put +12V into the K3's antenna connector. The results were not good: a burning smell from the rear of radio. The radio was in QRP mode (<10watts, so PA bypassed?) on 40m when it happened.
RX appears to be fine. The radio still makes 100W out, but the SWR reads 99.9 on all bands (into a dummy load). Also, the power control has no effect - power out is always 100W. Looking at the schematic, T4 in the SWR bridge certainly would have been fried by applying 12V to the antenna connector. What else did I damage?
