    Looking for schematic of a simple SWR meter

    I'm working with simple antennas, and I need a design of a simple SWR meter. It don't need to have high precision!

    Could you help me?

    swr schematics

    hello pal,

    You could try using a toroidal sensor to tell you whether there is any kind of mismatch in your load (open or closed)... I've an old R*F*D*E*S*I*G*N* that suggests a circuit for doing so... I'll try to scan it and upload it somewhere... any f*p's??? I've only 10 points and cant use the file manager...
    Will it help you somehow?

    swr meter demo

    Thanks IBall!! It's very interesting. I'll try it. This file has a reference to "FAR circuits", do you know? There are a PCB layout for this SWR meter.

    Best regards, Alexandre.

    construction swr meter

    I followed the reference to FAR Circuits to:

    w*w.farcircuits.net/

    I could find no artwork for this project, but the directional coupler subsection does not seem to use one.

    Glad you found it useful!

    three strips 1 " wide and 3 mm between each strip

    three diodes four resistors two caps and a connector and variable res to adjust the reflectoed power


    very easy stuff

    Re: SWR meter

    Using www.google.com and searching for

    SWR meter digital display

    gives several hits. For example:
