1) Symbol rates were tested up to 85 MSymbols/s
2) currently not implemented
3) 16APSK, 32APSK possible but 4dB slump in performance
4) Maximum DVB-S2 / S2X LDPC bit rate is limited to 720 Mbps. This bit rate is defined as symbol rate * bits / symbol, i. 8PSK 30 M symbols = 90 Mbit / s. The bit rate used is dynamically assigned by the driver. DVB-S channels do not contribute to the limit.
5) Single / Dual Demod using
