The K3NG ATU is an interesting design but uses several relays.  That is fine for automation
purposes, but I wonder if the design could be reproduced with a handful of DPDT rocker or
toggle switches replacing the relays.  Maybe there needs to be 2 versions of this well thought
out design, one that is automated and another that is manual for low current draw and increased
battery life for portable use.

The K3NG ATU lends itself to home brew.   And changes to the power level required. My own build I estimate at around 20-30W and uses smd 2-3kV caps (overkill) and the usual relay switching of L&C. Two relays are used to switch the ends for L-C or C-L. I used standard relays, not latching, due to cost here in VK. Control board uses a NANO with a 0.96" OLED display.
