I thought that installing MCU1.05 there would be ample RF sampling rates
taken to avoid erratic LED displays. The updated firmware seems not to be the
solution.
With a 50 ohm dummy load on the KAT100 output only the leftmost LED lights
up and K2 SWR is 1:1 regardless of power or band in

Getting a really good RF ground for a 2nd story shack may require more than
a 1/2 inch copper pipe, it may be a good ground at DC, but actually may have
a high impedance at RF (depends on the frequency).
The easiest thing to try is a quarter wave counterpoise wire (open at the
far end

Try adding several feet of coax between the tuner and the antenna and
try again. It appears you may have a voltage maximum occurring at the
tuner - adding the coax will move it out a ways. There are just some
impedances and feedline lengths that tuners have a difficult time
that did it, thanks
