[dvblast-devel] DVB-S2 modulators

[Nuno Mota]

This board can do DVB-S https://www.datv-express.com/Purchase/ShowBoardInfo
But you will need to hack this https://github.com/G4GUO/datvexpress_gui to
be able to input the multicast stream.

It's a very low cost compared with others. 300$ plus shipping
