Good point. Looking at the photo of my KX3 on top of Mount Willson in Henry Coe, I see two bars on the S-meter on 20 meters. That is miles from Silicon Valley. It was quiet and lovely, I could hear everybody. The filters were wide open, preamp on, and NR off. Zoom in and you can see for yourself. https://www.flickr.com/photos/walter_underwood/17417496311/in/album-72157652448882921/ <https://www.flickr.com/photos/walter_underwood/17417496311/in/album-72157652448882921/> wunder K6WRU Walter Underwood CM87wj http://observer.wunderwood.org/ (my blog) ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:[email protected] This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html Message delivered to [email protected]
