If you have the KXV3 (the so-called 'transverter interface' which is much more than that) you can simply connect the noise canceller between the RX IN and RX OUT. This enables you to avoid using the kludgy relay in the device for t-r switching. Bill, is that in order of increasing or decreasing effectiveness? -- 73, Vic, K2VCO Fresno CA http://www.qsl.net/k2vco ______________________________________________________________ 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
