Hi,

A very nice looking amp.  A few questions:

  I assume from the detail description that the KXPA100  face plate 
sans the built in  ATU would have just the upper row of lights, Power 
out, ATT, TX, ON .... and the OFF/ON slide switch.

I assume that the sans built in ATU version would automatically 
bypass the amp when in the OFF position.

I also assume that the attenuation, ATT light is activated 
automatically as is the band selection.

At what power level will the automatically switched ATT kick in?

At the moment my favorite antenna tuner (manual) is the ezee match 
which is very easy to tune and has 2 separate antenna 
inputs.  Physically the KXPA100 would fit very nicely on top of the 
AT case (exactly 6 in wide and 12 in deep).

I assume, that should I wish to add the built in ATU in the future 
that it would include a new faceplate with the added lights and buttons.

Thanks
