Hello to all. Maybe that I don't understand the real utility of the roofing filter but I observed this. Last saturday, we were on a SOTA summit using two KX3s about 40 feet appart transmitting CW at 5 W. And even with the roofing filters on, we heard each other's sending as a diffuse noise. I know that changion RX shift to 8 disable the roofing filters, but we were not using that shift.
So, am I missing something about the use of these filters? Are they designed for operations with operators near each other like SOTA activation on a crowded summit ? 73, de VE2PID KX3 S/N 190 ______________________________________________________________ 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
