I got the sub receiver fixed. The previous owner had the filter inserted the wrong way. By this the signal pins are shorted to ground through by the filter.
I discovered this by measuring on the pins of the filters. On the selected filter the signal pins carry 5 volt DC. The DC is blocked by capacitors on the filter circuit. When having few resources, you can swap the NB and mixer print and also change coaxes to swap main and sub receiver. -- View this message in context: http://elecraft.365791.n2.nabble.com/K3-Sub-Receiver-Problems-tp7568116p7568737.html Sent from the Elecraft mailing list archive at Nabble.com. ______________________________________________________________ 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
