Hi all, I have an end-fed antenna with some random wire. The UNUN at one end of it has three sockets to plug the random wire in: 1:4, 1:9 and 1:16.
My KX3 has the built-in ATU. I now want to find out on which band I best use which one of the sockets. As a first step, I wrote a simple program kx3lc.py (see https://gist.github.com/anonymous/5d53f5bdbc50782a9d5e2c8d7062be69) that can give me an output like this: holger@laptop:/usr/src/afu/kx3/swr$ ./kx3lc.py L: 0.12 mH, C: 203.0 pF on transmitter side Am I right to assume that the ATU settings with the lowest L is always the best? So when I have (for the three sockets), these values, L: 0.12 mH, C: 203.0 pF on transmitter side L: 0.0 mH, C: 246.0 pF on transmitter side L: 0.0 mH, C: 256.0 pF on antenna side (but lowest SWR 1.2-1) ... that the middle socket is the best? 73 Holger, DH3HS PS: those values are all bogus, I measured when when my end-fed was in a big curl inside my shack ... ______________________________________________________________ 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 Message delivered to [email protected]
