[Hackrf-dev] how to set IF in GNU Radio for HackRF

[Karl Koscher]

Use a Complex to Float/Real and Float to Char type converter block between
the HackRF source block and the file sink, and then change the file sync
type to char. Or you can use the hackrf_transfer program and avoid these
conversions altogether.
