I'm confused, are their radios that in real-time tune a LC network to whatever band/frequency you are on? If you use an analyzer to graph your VSWR curve across a band, and you are pretty flat (say 1:1.5 across the whole band), then you really don't need to re-tune after the first shot. However, when you switch bands you switch frequency which means unless your VSWR is low across all bands of interest, you need to tune up again. I think though the ATU has some memory with respect to what band you are on which helps. I don't think the K3 is any different than other high-end rigs? Am I wrong? -aps (KC2ZSX) ______________________________________________________________ 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
