Little extra Al tests are made on 3604. When I pick diver end bands it gives me diver end outcome so 3 band are really 1.0. - 1 some 1.3 - 1 so its also depending on the band, I have a G5RV I am curious what happens without a tuner Going to test that later, wife is waiting and have to be the man in the house :-))
Nice testing this really is a nice group with a lot of nollage.. 73 PE1BSB -----Oorspronkelijk bericht----- Van: Elecraft [mailto:[email protected]] Namens [email protected] Verzonden: woensdag 20 juli 2016 21:21 Aan: [email protected]; [email protected] Onderwerp: Re: [Elecraft] K2 automatic tuner PS i have the shield update. -----Oorspronkelijk bericht----- Van: Elecraft [mailto:[email protected]] Namens [email protected] Verzonden: woensdag 20 juli 2016 21:18 Aan: [email protected]; [email protected] Onderwerp: Re: [Elecraft] K2 automatic tuner Ok Don and Knut, Its getting better :-) I tryed a antenne analyzer, gives me the same as my K2, so I think K2 is fine. The AT-100 ( just bought it second hand, has two antenna connectors wich I can switch. Put a dummy on the other port then switched an tune the dummy 20 1.0 - 1 so looks ok Did the same with connectors reversed so antenne 1 is antenne 2 again 20 1.0 - 1 But with the antenne it stil give me the same as my antenne analyzer. Is this the tuner ??

There is also the possibility that RFC10 (on the back of the SO-239 jack) is coupling with the base K2 - and that condition is worse if the shield is the older one with a wide notch above the SO-239 jack and no solder lugs from the SO-239 jack to the top of the shield. I am not saying that the problem is restricted to 40 meters, only that it is more apparent on 40 than on other bands. If the KPA100 has the older red core toroids at L15 and L16, it should be updated with the KPA100MDKT because that mod was created to address exactly that problem. If the shield needs updated, the KPA100SHLDKT is available. 73, Don W3FPR On 7/20/2016 2:38 PM, ab2tc wrote: > Hi all, > > I can think of one other *possible* explanation, although far fetched. > If the K2 transmitter has excessive harmonics or parasitics, this > could happen. > The out of band energy is readily absorbed by the dummy load but not > by the tuned load presented by the LDG tuner.
