Filter board design

[Mario Vano]

Hi all:

I've finally gotten around to publishing the filter, vswr bridge and t/r relay board design that I've been using on several successful radios for some time.

Note that I have no plans to make pcbs or completed boards available, but the design is MIT licensed so anyone who would like to do that is encouraged to do so.

Here's the Github: https://github.com/mpvano/LPF2

and here's a picture of it in use during testing:

Note that the radioberry board is usually stacked on top of the filter board. This radioberry has pass through pins on the GPIO.

enjoy!
