Precisely!!! I'm trying to diagnose a K2 fault at the moment. I'm largely acting as a robot directed by Don Wilhelm, thank goodness for Don& Gary. I would be even more at sea, out to lunch, if I were trying to cope with a fault in the far more complex K3. I've read the K3 manual carefully [fb user manual!] and I still don't have a clue as to circuit level function, sufficient to infer fault from malfunction.

Without some explanation, the downloaded schematics are pretty worthless to somebody trying to understand the radio. In particular, the published K3 block diagram is an exercise in obscurity. In my opinion, it's nearly impossible for someone even to follow the receive or transmit signal path. 73, Jim W8ZR -- This message has been scanned for viruses and dangerous content by MailScanner, and is believed to be clean. ______________________________________________________________ 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
