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?

simple swr circuit

thanks 2000,

i would like the schematics and also the PCB (if it's a critical design). i was thinking in a circuit that can be used with multimeter.

thanks a lot.

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!

pal swr meter

you need to make a small pcb to cover from 0 - 100 mhz

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

simply type into G*oogle.com
