Guys, i still could not solve the problem with the sub-rx. Over the weekend i opened the K3 and checked all TMP-cables, they are in their correct places. The pins of the sub-out and the sub-in board are correctly mated with their sockets. The Aux-DSP ist seated correctly etc etc.. In short, to me everything looks fine. I carefully read the manual in order not to make any mistakes with the antenna-connections and/or the selections of the antenna inputs.
The sub-rx *will not work*. I have : Noise , but no band noise. Faint signals, but this might be a leakage from the main-rx. A 2.8khz & 400hz filter in position FL 2 & 3 , so even if i counted the positions backwards , one of them should work. So, what can i do? Can i swap some connections to pin down the defective board? -- 73, DM4iM ______________________________________________________________ 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
