I have observed some different SWR readings on 10 and 6 meters with relatively small differences in cable lengths between rig, amp, and ATU. My K3 works better on 30 meters when I engage the K3's ATU. The K3 is measuring the SWR it sees (the input to the amp or the ATU, depending on the amp key line), and the KPA500 is measuring what it sees (the input to the ATU) and the KAT500 is measuring what it sees (the antenna system and the ATU's L and C), and they're all at slightly different points in the path with cables of varying lengths between.

All other bands are 1.1:1 or better. That's with the K3's internal tuner in bypass of course. 73 Ron AC7AC -----Original Message----- From: [email protected] [mailto:[email protected]] On Behalf Of Fred Jensen Sent: Saturday, December 08, 2012 2:18 PM To: Elecraft Reflector Subject: [Elecraft] KPA500 - SWR into K3 In 10m contest [CW], I'm seeing 2:1 SWR on the K3 display feeding the KPA500. SWR from the antenna to KPA500 is 1.1:1. Is this normal? 73, Fred K6DGW - Northern California Contest Club - CU in the 2013 Cal QSO Party 5-6 Oct 2013 - www.cqp.org ______________________________________________________________ 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 ______________________________________________________________ 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
