SWR meter

SWR "power" meter to measure reflected RF on an antenna.  Change the LC tank or the resistor (right) to increase reflections.

UPDATE: trying to show reflection magnitude with op-amps -- this is totally beyond my skill level.  If I tried to hook this up to arduino, I'd need the output to be between 0 and 5 volts I think.  This setup otherwise seems to work to me.
