Pardon my ignorance but I don't understand how your station layout would be improved with an external ATU. The KAT3 occupies the same space inside the K3 as the KANT3. An external tuner would result in more, not less, space being taken outside the radio (albeit remotely mounted), plus you'd have another cable to route. There may be something about having a 6m beam that works better with a remote ATU and that's fine -- I just don't understand how this is all driven by limited desk space. The same amount of desk space is taken up with the ATU inside the K3 as outside. Craig NZ0R Instead of small I should have said modest, i.e. 100w max from a K3 (I hope) running barefoot feeding a 100ft doublet at 27 feet squashed into a garden 90ftx 30ft including the house. The proximity of neighbours prevents more than 100 watts. With this system I have already worked most continents on SSB. The rig has an output impedance of 50ohm into 30ft of 50ohm cable so the place to fit the ATU and balun is between the 50ohm cable and the open wire feeder of the doublet. The shack is in an upstairs front bedroom and the feedpoint is at the back of the house. And this is nonnegotiable. Hence the need to have the ATU remote from the rig and the antenna switching in the rig so that a second 50ohm cable can feed a 50ohm yagi direct not needing an ATU. OK yes this does introduce the need to weather proof the ATU but there are several on the market already some suitable even for small boats in far more extreme conditions. My wish was for an ATU designed to work specifically with the K3 taking advantage in the auto tune facilities with a one touch action.
