I believe that the K3 tuner does have more range than the one in the KAT500.
My experience with this kind of system (tuner -> balun -> open wire line) is that the 1:1 balun works much better from the point of view of losses and choking off RF in the shack.
What do you mean that the 4:1 balun has less range on 160 than the 1:1? If you are saying that the SWR curve is broader, then that could just be because of losses in the balun.

Is the tuner range of the K-3 and the KAT-500 the same? They seem to tune the same antenna differently, (of course the K-3 is tuning through a bit more coax with both the KAT-500 and KPA-500 on standby.) They are tuning a 250’ Doublet via a short coax run (10’) to an external 4:1 current Balun, then via true 600 ohm open ladder line. (I tried a 1:1 Balun, but it did not have as great a range on 160 as using the 4:1.) The K-3 seems to have a bit more range than the KAT-500. Is that to be expected? 73 Kim - K7IM ______________________________________________________________ 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]
