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
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
