I found out similar behavior with K3 while testing it for the first time in SAC contest.
I was sure that the noise was some kind of power line noise or similar. After the contest I disconnected *all* electrical devices but noise was still there. Changed to FT1000 Mark V and the band was quiet while with K3 I had S3 to S5 noise. It cleared out to be the problem with K3 preamp. Every time when preamp's turned on, the band are really noisy but switching preamp off make the noise go away. I guess it's not the "K3 has the best RX" issue but problem with preamp. 73 de Toni, OH2UA > All four are equally quiet without an antenna connected and with a dummy > load connected. When connected to an antenna the K3 has about 2 S units > more noise indicated than the other radios connected to the same antenna > (A/B switch) and the noise level sounds about that much louder. ______________________________________________________________ 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
