Have you compared the two rigs with their antennas disconnected? Are they both on the same antenna? Have you calibrated the Icon/K2 S-Meters with a known 50 microvolt signal? What band are you on? Just a guess, but it sounds like the K3 has a more sensitive RX than the other two. 73, Tom, N5GE [email protected] K3 #806, K3 #1055, PR6, XV144, XV432, KRC2, W1 and other small kits. 2 W2's on order 1 K144XV on order http://www.n5ge.com http://www.swotrc.net ______________________________________________________________ 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
