The K3 already suffers from ergonomic overload and lack of flexibility with antenna selection, audio routing, etc. even when just using diversity in SO1R. True SO2R adds another level of complexity to an already overloaded interface. Given this, I believe there are higher priorities to work on with the K3 and save SO2R for a better human interface in the K4. 73, Bill W4ZV -- View this message in context: http://n2.nabble.com/K3-SO2R-in-a-box-tp3835713p3836391.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:[email protected] This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html
