This is a project to connect two Linux machine's network stacks via the amateur radio bands. It uses Linux's TAP interface to read & write packets at layer 2 to/from the kernel. QPSK modulation is used at the RF layer.

For now experimentation has mainly been done in a Ramsey box. The next step is to add a callsign field to the QPSK frames so the data can be legally TX'd.

You'll like my IP over DVB-T2 test bed using GNU Radio. It uses the ULE protocol dvbnet driver that's built into Linux.

Not shown on the diagram is that it also supports IPv6.
