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
