In both cases the ATU had no trouble making a 1:1 match. The actual measured SWR of the antenna system (ie, with an SWR meter) is 3.7:1 on 40m and 2.9:1 on 20m. Not a great match obviously, but expected for what it is. Nick -- *N6OL* Saying something doesn't make it true. Belief in something doesn't make it real. And if you have to lie to support a position, that position is not worth supporting. ______________________________________________________________ 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]
