Well, rats. My K2, with antenna tuner, got hit by a nearby lightening
strike. It still works ok, but it's deaf. Where do I start looking for the zap? _______________________________________________ Elecraft mailing list Post to: [hidden email] You must be a subscriber to post to the list.

Sorry, but with that sort of question, the only practical answer is that you
start looking somewhere inside the K2 enclosure. You will have to define 'deaf' a bit better. If it works OK, then there is nothing wrong!!! We can help best if you are clear and unambiguous in your descriptions. If it has weak receive signals, that is another matter, and you should try the Reciever Signal Tracing outlined in the Troubleshooting part of the K2 manual. If the receiver has no output at all (not even noise) then start tracing in the audio stages and work your way toward the antenna until you find the dead stage. Once you isolate to one or 2 stages, we can help you isolate the failing components. One consequence of lightning zaps is there may be multiple failed components, find them one at a time. 73, Don W3FPR > -----Original Message----- > > Well, rats.

I would add two things here:
1. when you open the case up, a careful examination may reveal at least some of the discharge path, damaged parts, and so on, but you will most likely have to do the signal tracing that Don mentions. 2. I note that frequently you will find that you are at the beginning of your problem; ESD events (of which Lightning is the largest I know of) can leave a lot of the semiconductors inside "walking wounded", only to die later. Be ready to have this become an iterative process. Best wishes for a speedy recovery for your K2. 73 de W5SV, Dave W3FPR - Don Wilhelm wrote: >Sorry, but with that sort of question, the only practical answer is that you >start looking somewhere inside the K2 enclosure. > >You will have to define 'deaf' a bit better.

He probably already did that, but now he wants to repair the burned up one to have a second rig :) _______________________________________________ Elecraft mailing list Post to: [hidden email] You must be a subscriber to post to the list.

If the insurance company paid for it, they'd also physically take it.
