column r/w Enumeration

The receive filter Roll-off factor setting determines the spectrum excess
bandwidth by controlling the RCRO (Root Cosine Roll-off) factor of the matched
filter at the demodulator input. The lower the Roll-off factor the higher the
throughput. Note that increasing the throughput (higher symbolrate) requires
more power from the satellite or it will result in a lower carrier-to-noise.
