Arduino RF power & SWR meter
My primary interest was for vhf/uhf/shf, i have foreseen positions for 6m, 4m, 2m, 70 cm, 23cm and 13cm bands - but you can use the arduino readout on hf as well

A Mini Primer on SWR Measurements
Every radio ham needs an SWR meter. Even though comercial rigs have builtin digital readout SWR meters
A Small Digital QRP SWR Meter with OLED Display
Most accept that transmitters operate best when the power output is connected to a load which presents an SWR below 2:1. For example, 100 ohms, 25 ohms
Antenna Reflection and SWR Calculator
VSWR return loss and reflection coefficient, which are different ways to express how well a load is matched to a source
