WolphiLink Rig Audio Interface

Doing much portable and backpacking I needed a quick small interface for cell phone / tablet to radio interface to do digital modes. I came across the wolphink project. A neat simple easy to put together audio interface.

The schematic is below as a go by

This might seem hard to get your head around but I did a little guide using a perfboard for you to use

And in the end you get something like this...

You can if you have access to a 3d printer do a nice little enclosure for it and the free 3d files can be downloaded for free here

To make one yourself will require a perf board and some parts:
