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?
