FL2K transmission support

[cr08]

I am very curious since there's already support for other TX hardware, any chance of adding support for FL2K dongles? Been doing some playing around off and on trying to get something going myself but have had no luck. Even if non-real time and I have to pre-generate an HD signal, I'd be happy with that. I'd love to give this a test with some production HD receivers I have but the current supported TX hardware is well out of my price range.

Using pybombs to build gr-nrsc5 fails. I'm assuming it's due to the fact that gnruadio is now at version 3.9 and the cmake file requires version 3.8. FWIW, building gnuradio with pybombs also fails. My workaround was to just build gnuradio from source making sure to use the --recursive option in git to make sure that volk and other dependencies get downloaded, compiled and installed. Once the gnuradio build was completed and installed, I then built gr-nrsc5 from source but had to edit the cmake file to look for gnuradio version 3.9
