Diz has a nice kit for an inline SWR/Power indicator,? $12, good up to 100W. If we had a couple spare analog pins at the Raduino, could use that for sensing.

No, it's not meant to be left in line, as it sucks up all the power and is not a "sampling" wattmeter. Peter Parker had a really simple sampling as a tuning indicator using a toroid, a couple of turns of wire, and an LED with the coax passing through the center. When I saw that, I wondered if it would be possible to use a similar sampling scheme and map it to a Nano. If? calibrated with a known source, I wonder how accurate it might be.
