I don't have the schematic in front of me, but I had this same problem when I did my build, and I finally traced it down to a diode that I somehow failed to install. Usual signal tracing applies -- you have audio, so work your way back, stage by stage, until the signal disappears :). Most of the time, just touching a screwdriver to a part in the signal path is enough to let you know where the path is in-tact, and where it's broken!

Thanks for your help Phil. Yes it's broadband noise with another small higher pitched tone in the mix that does not include any of the assortment of other odds and ends you commonly hear when tuning up and down the band except for one very strong broadcast carrier right down close to 7.000 that's in our area. So if the signal is strong enough, as that carrier and also the 5 watt tone from my ts590 into the dummy load, it will get through. The noise level is the same whether or not the antenna is connected. Connecting the antenna, any antenna, bringsSo something is definitely wrong. -- View this message in context: http://elecraft.365791.n2.nabble.com/K-1-Poor-Receive-New-Build-tp7600322p7600333.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 Message delivered to joberreu-elecr...@moselle.com
