Remote operation via usb serial or ethernet (new). The intercept point is the power input required by the ad8307 to give a theoretical 0v output. This time with nextion tft screen. The arduino platform lends itself nicely to other pursuits, and one of these is amateur radio. This should keep the output power at a constant level. Maybe you would like to learn more about one of these?
Alternately, a coupler with diode detectors can also be used.
Although i bought the book and respect the copyright of the authors i will share my own schematic here. Arduino based simple swr and power meter. Swr is easier than power because it is a ratio and the absolute values don't matter so much (within a certain range). As this 'monimatch' type of bridge is frequency dependant, the meter must be calibrated for every band. Pcb assembly service starts from $30 with free shipping all around world + free stencil.
