I sent this to Elecraft support, but I thought I'd post it here too to see if the collective wisdom of the group might have anything to add.
Tonight during dinner I noticed my K2/100 (w/ KAT100) was showing no noise on the S Meter. I unplugged the headphones and could hear no signals at all, as if the antenna was disconnected. If I tried to tune, the ATU would light up (sometimes) and it would run a tuning cycle, but I don't know if it was finding a match. No noise at all on the bands. I started taking the panels off and the next disconcerting bit was when bits of plastic started falling out. Q11 and Q8 are both split in half with most of the body of Q11 loose in the chassis and the base side of Q8 split from the collector & emitter. I had left my radio on this afternoon while I was a few doors up the hill working and we had a short thunderstorm. There were no close strikes (very little lightning at all) but yeah, I should have disconnected things but didn't realize I had left it in that state. A visual inspection doesn't show anything else obviously wrong aside from some slight scorch mark where Q11 went boom. No traces look blown and there are no signs that any of the caps or resistors in that area are damaged. Aside from Q11 & Q8, are there other likely candidates for replacement or places to check? The ATU & PA100 pass a visual inspection. The storm is a pretty strong correlation, but are there any other likely scenarios that could cause this failure?
