Dan - I have the same antenna and the same balun. It is a great combination from 160m to 10m. Before I used the balun, however, I used a balanced Johnson Matchbox. I found that I had to add some length to the original ladder line (about 18 feet) to get all bands to match (including all of the WARC bands). 30m was my toughest band, but once I got 30m to match nicely then all the other bands matched too. So you might try adding some ladder line to the original feedline. (Subtracting may also be effective but I added).
I love QSYing from band to band now with the K3 or K2. The K2 and K3 tuners remember the settings so I am instantly matched without having to generate RF. Good luck. 73, John W2XS My configuration was Cobra Senior Ultralight up 60-66’ at one end 45-50’ at the other with center up about 55-60’ | 81 feet of 450 ohm ladder line runs that runs about 1’ foot through a casement window | Balun Designs 4:1 4113t current balun | 3’ coax with 239 – 239 connectors [703+] OR an amphenol 239/BNC adapter [KX-1]. -- View this message in context: http://n2.nabble.com/KX1-KXAT1-ATU-questions-tp4248233p4253325.html Sent from the [KX1] 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
