Hello Dwight,
Sorry for the delay, your email got moved and I've been busy as s.e.s. 
W6D for Route 66 On The Air.
I used my KX3 with no amp and a 75meter wire loop at about 20ft for 
Field Day and went coast to coast and border to border at 10w.
Tuner situation - I run a Yaesu FT 950 and don't use the onboard tuner 
because I get much better results with an MFJ 969 manual tuner, which 
will almost tune lawn furniture. I use the ATU in the KX3 (which 
apparently *will* tune lawn furniture) because it gets better results 
than the MFJ 969. Sorry, can't help with the amplifier part of the equation.
73,
Bruce W6WW
