TXC, TXD, RXA, RXB, RXC, and RXD to the new data/code rates.
Note: The data/code rate assignment in the Utility menu must match the filter
assignment on the daughter card. Each daughter card is labeled with the filter
assignment (A, B, C, and D) and associated symbol rate. Example: The label for
a 64 kbit/s, 7/8 rate, QPSK filter is 36.57.
Turn ON the RF output.
