I’m building a K1 for a fellow ham whose hands won’t allow the fine soldering work that this kit demands. This is the second K1 that I have built.
All of the test points before alignment and test, part 1 have been nominal. I have successfully completed the tests on the LED and LCD/Error Codes without problem. When I plug in a pair of stereo headphones, the funny business begins … There is no output from the headphones. I rotate the AF GAIN without change. And, the LCD display immediately goes blank when I plug in the headphones. That said, I can remove the headphones and see the display fine. I can tap the MENU, set and edit the STL and STP without a problem. But, plug in headphones and the K1 goes blank. I have been reading this list long enough to know that 99% of problems during a build have to do with cold solder joints. I believe I’ve looked at the solder joints. I reflowed the 3 joints at the headphone jack. Any ideas about how to troubleshoot this problem? I’m missing something in this process. I will go back and make sure that I haven’t left any parts out, but I don’t think this is the case. Thanks in advance. gene WG7GW ______________________________________________________________ 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]
