Tom, You may have a high-power AM broadcast station close by, or in the favored path of your antenna. I suppose your house wiring and/or gutters could be forming a high-gain NVIS antenna on some band…. In any case, try setting MENU:RX SHFT to 8.0 on any affected band, and/or reduce preamp gain on affected bands from 20 dB to 10 dB using MENU:PREAMP. 73, Wayne N6KR ______________________________________________________________ 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
