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.

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.
