Thx & 73, Fred/N0AZZ -----Original Message----- From: elecraft-boun...@mailman.qth.net [mailto:elecraft-boun...@mailman.qth.net] On Behalf Of Stan Gibbs Sent: Thursday, December 13, 2012 10:30 AM To: elecraft@mailman.qth.net Subject: Re: [Elecraft] K3 Front End Protection Fred, The best source of good information that I have found on operating multiple radios safely is the book by George Cutsogeorge, W2VJN: "Managing Interstation Interferrence". It covers all the issues with running SO2R as well as other multi-transmitter configurations, and provides techniques to measure interference and mediate it. The book is available from Array Solutions here: http://www.arraysolutions.com/Products/Books/W2VJN_Interference.htm Antenna isolation is the name of the game and, particularly with QRO, requires a great deal of care and planning. I run 100W in an SO2R configuration with 2 K3's on a small city lot. My solution to the isolation problem has been the use of W3NQN bandpass filters and antenna geometries to minimize interaction. Using W2VJN's analysis techniques and employing some of the possible solutions noted by him, I can operate safely and have confidence that I am not damaging my K3's receiver. ----- 73, Stan - KR7C -- View this message in context: http://elecraft.365791.n2.nabble.com/K3-Front-End-Protection-tp7567094p75671 00.html Sent from the Elecraft mailing list archive at Nabble.com. ______________________________________________________________ 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 ----- No virus found in this message.
