Hi Iran, I changed the subject line to reflect that this thread is continuing as a general troubleshooting exercise with your K2.
The NE602 product detector has a balanced output circuit and unless you use a differential scope probe (or do the CH1 - CH2 trick with your single-ended probes) you will mainly see bleed-through of the BFO on either output pin. Your subsequent post indicated that you ran the BFO test and it passed? What do you hear at the audio output, either speaker or phones? Can you hear the tone from your signal generator as it's down-converted and amplified? 73, Mike, K8CN ______________________________________________________________ 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 Message delivered to arch...@mail-archive.com
