Brett and All,
While I can't officially confirm the KAT3's tuning range ability, I can tell you that it is pretty darn good! It certainly is much better than just about any other inboard ATU I have used. Elecraft claims a 10:1 range, and I have no reason to doubt it. Currently I am in a travel status, and have been using my K3 (KAT3 included) from my car. I'm not really using it mobile, but I have been making a few QSO's while parked in front of my brother's house here in Ventura, California. The antenna I threw in the car to play with is NOT one I would consider to be very efficient. I picked this one up at Pacificon last year, and it is sort of a "poor man's Outbacker" (not that the Outbacker is all that efficient either). I didn't pay very much for it, that's for sure! Anyway, on 40 meters I more or less tuned the antenna outright for about 7100 khz. From there, the KAT3 will tune the antenna at either end of 40 to 1:1. I've had QSO's at both extremes. That's not a very scientific confirmation of the quality of my signal, but at least the K3 is happy with what it is seeing. On 20 meters my reports have been surprisingly good. Much of the time I was only running 30 or 40 watts to keep the current draw down. As a comparison, I can tell you that at home my FT-1000 Mark V internal ATU doesn't like what it sees on the upper part of 40 meters where I am using an R7 vertical. However, the K3 has no problem with the same antenna setup. I'm not sure what your expectations are, but if they are reasonable, you won't be unhappy with the KAT3.

Brett,
This is from the FAQ page (lots of great information there) Will the KAT3 have similar specs as the KAT100? Specifically, will it match 10:1 SWR loads? The K3's KAT3 ATU will match a range of 10:1 through 100W. ------------------------- 73, Greg - AB7R Whidbey Island WA NA-065 K3#0009 On Thu Jan 31 2:20 , "Brett Howard" sent: >So I was recently reading about the IC756ProIII and noticed that it said its >tuner was rated for 3:1?

I've never used the auto tuner in my Pro III or TS-2000x. I didn't order one with my K3 as I hate auto tuners. Go buy a good old Dentron MT-3000A. It will tune anything.......

Sure! And lug that thing around too when you travel! ATU's
definitely have some advantages, but admittedly they aren't a total solution.
