The KX3 has extra range so that it covers 160 m and 6 m compared to the KX2, which is 80 to 10 m. The T1 is spec’ed to cover 160 to 6 m, so I’m not sure about the details of that.
The KX3 might have a wider matching range on just the HF bands. I’ve only had it fail to match once. A few years ago, there was a discussion on this list that gave all the component values for all the ATUs. I’m not having any luck finding those posts right now. wunder K6WRU Walter Underwood CM87wj http://observer.wunderwood.org/ <http://observer.wunderwood.org/> (my blog) > On Oct 25, 2022, at 9:51 AM, Julia Tuttle <ju...@juliatuttle.net > <mailto:ju...@juliatuttle.net>> wrote: > > Hi folks, > > I was looking at Elecraft's antenna tuners, and I'm a little confused at > their specs. > > The T1 and KXAT2 are listed as having 7L7C networks, while the KX3 is > listed as having an 8L8C network, but all three are listed as being able to > match up to a 10:1 SWR. > > Why doesn't the KXAT3 have a wider matching range from the extra inductor > and capacitor? > > Is the 10:1 spec conservative and in reality all three can exceed it but > the KXAT3 will outperform the other two?
