Hi, My K1, #2799, build was going along swimmingly until I built and installed the KNB1 module. Some adversity must enter in to every project, I suppose, because now my poor K1 is deaf, even after removing the K1 and re-installing capacitor C22 that is removed when installing KNB1.
Both with the KNB1 installed and now that I have removed it, there is no difference in background noise when I attach my N-GEN noise generator and turn it on; it used to be pronounced. Nor can I hear even the 50uV tone from the X2 when before the 1uV level rattled the speaker housing at a moderate volume. My intention today was to re-calibrate the KFL1-4, so I removed the KAT1 and moved the RF DET jumper to the K1 side. I reset the trimmer capacitors to horizontal and attached the N-GEN and discovered something was amiss. Turning the N-GEN on had no effect on the noise level in my headphones, which now have more hiss than I remember when I just have a dummy load attached. I will ask Elecraft directly as well, and I will go back and re-check the resistance and voltage verification blocks, but I was wondering if anyone had other ideas for things I could look at while I have it all apart? 73, Byron KI6NUL ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html
