VSWR - Monitor

In the famous dutch QRP nieuwsbrief (NB 62) i found the article: "SWR METER ZONDER AFREGELING" door PAoWDW

Also in the openhpsdr ALEX project they are using the same bridge.

I added a i2c adc component and did make a PCB for it.

 

Picture shows the result:

 

I did interface this with my emulator so iam able to see the power when using the pihpsdr software:

 

 

As you can see the power using a PA is set to 60 Watt... and using a dummy load during the test indicates a nice SWR!

For more information and all the details see the repo at github!

Also created a release for the radioberry project including the reading of the power!
