Picked this tuner up at a nice price the other day. Its missing the dummy load resistor and the pc board that has the swr sense circuitry. Curious how hard it would be to
build a board and populate it with the correct components?

In this video you can see the dummy load and the other thing, I guess F1 at about 3:10 mins in. Plus the SWR board mounted the same side. He shows the schematic also at some point.

Was also wondering about building a "protect" mode somehow, where if I could find the right resistor, rigg something up where all the antenna inputs get grounded thru the
dummy load, as a means to protect the system from lightning strikes.
