RaDAR – Manual tuners

A good friend gave me a MFJ tuner a few months back and today I took the time to delve a little deeper into the details of the tuner. The circuit diagram may look complex but really just a simple high pass tuner design. The complex part is simply just for the metering. I was using it as a SWR meter only, till now.


Then I went looking on the Net for similar circuits and comments and found a few interesting ones. These are just variations of what we see above. A pretty versatile way of interfacing the 50 ohm rig connection to anything else!




So I have this awesome tuner, maybe it’s time I started using it!
