Simple RF Power

- The board shown here has two separate detector circuits on it, and is the one I now use for monitoring both forward and reverse power with a dual directional coupler, and for providing an SWR trip signal

Swr Meter Links →
SWR meter
The meter automatically provides an accurate readout of SWR for any power level between 10mW and 1000W
Wifi VSWR Meter
The illustrated circuit is a VSWR meter for the VHF-UHF-SHF. This includes the Wifi 802.11b - g, 2m, 70cm and 13cm of the Amateur Radio bands
FT Meter per Yaesu FT-857 / FT-897
A nice and useful accessory is the FT Meter for the Yaesu FT-857 - FT-897 series. This tool can be built with common components
Meter and Low Power Tune for FT-857D
My new Yaesu FT-857D is pretty cool, but it didn't have a Tune button like the old TS-440S, which would put out a CW carrier at about 10W
A PIC16F876 based, automatic 1.8 - 60 MHz SWR/WATTmeter
This project was developed by a little group
