Progetto SWR meter
La realizzazione richiede piu' abilita' meccanica che elettrica

Power and SWR Meter
This update replaces the teensy ++ 2.0 microcontroller with the much more powerful teensy 3.2 32 bit arm cortex-m4 running at 96 mhz

QRP SWR Meter
The measurement is based on the Wheatstone bridge

Standing wave ratio,Wikipedia
SWR is used as an efficiency measure for transmission lines

Swr Meter Wi-Fi 2,4 GHz
Build an accurate SWR meter at very low cost for 2.4 GHz WiFi frequencies
