Until I get the KX1-8030 installed this is just speculation - so FWIW.
I have ordered the Altoids Longwire Antenna Tuner from www.qrpkits.com.
For $30 you get a small L network tuner with a max 16uh and 270pf. As is,
the cap is only at the output end, but that can be made switchable
to put it at the input side when needed.
If the KXAT1 can't tune my antenna on 80 I will try the ALT as a
'pre-tuner'.

Hi Elecrafters,
For field operations with a KX/40.30.20m, I currently use a 28 feet
random
wire at the end of a 22 feet pole, and an single 16 feet radial on
ground.
The computed impedance is 89 - j 341 ohms at 7 MHz, matched by the
KXAT1.
However, at the low end of 80 m, it should be around 54 - j 1316 ohms,
giving very high SWR. Can the ATU match such values?
