On the www.lan23.ru are updated page for building wifi swr meter. mcWit was able to find replacement of the BAT62-03W Schottky diode used by pe2er.nl in his design. New diode is hsms-2822

There are several changes in the elements in due diode change. I can’t understand everything written on the site. But everything is there and all is build and tested.

Now just need to wait for more documentation.

Here is a picture of the finished device :
