That's not as much a dig as it might sound. A common occurrence after
lightning damage is for components to weaken and then fail later on,
on their own inconvenient schedule.
A question for the K3 repair guru's...is a lightning damaged board

Actually, wasn't a dig. I understand why there would be reluctance to touch a
lightening damaged radio, given the issue you (and the vendors at the time)
raised.
Which is why I'm kind of surprised Elecraft would do it, unless there were a
caveat in the fine print :-)

Some companies bring out new transceiver models every year or two. Our
