Whew! Not a good feeling-but it can happen to any of us, regardless of how careful we are.
Elecraft has been very good on suggesting helpful modifications to the radio. Any thoughts? Perhaps an in-line diode? I'm not sure if that would result in a significant voltage drop-just a thought.

There was a lot of smoke and the breaker popped. The RX and TX appear to have survived, however the internal 100 Watt amplifier now shows an over-current fault and quickly switches off. I haven't dared open it up yet - far too depressed now. I'll leave it till next weekend. Any comments on what I might expect to find inside and how to idiot-proof it for my future operation? 73 Roger KK3RW / G3WEW ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:[email protected] This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html Message delivered to [email protected] ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:[email protected] This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html Message delivered to [email protected]
