QRP VHF/UHF SWR meter -Reflectometer

    A SWR meter is a very basic measuring instrument which is used to measure the voltage standing wave ratio (VSWR) in a transmission media. If you are working with radio waves and antenna experiments, this is a must instrument you should have. Its not that complicated to build one and our intention here is to just get the indication of level of VSWR in a particular transmission path.
