See MR command.
Where: nnn.nnnnnn = Frequency in MHz, 50.000000 to
90.000000 and 100.000000 to 180.000000 in 1 Hz steps.
Note: When the modulator frequency is programmed, the
RF output is switched off.
Where: xxx = ON or OFF.
Where:
x = A, B, C, D, or V [preset designator].
For CEVD FEC: nnnnn = 1/2 (QPSK 1/2), 3/4 (QPSK
3/4), 7/8 (QPSK 7/8), BP12 (BPSK 1/2), OQ12 (OQPSK
1/2), OQ34 (OQPSK 3/4), and OQP78 (OQPSK 7/8),
BPSK (BPSK 1/1), QPSK (QPSK 1/1), OQSK (OQPSK
1/1), 16Q34 (16QAM 3/4), 16Q78 (16QAM 7/8)
For TCM FEC: nnnnn = 8P23 (8PSK 2/3), 8P56 (8PSK
5/6)
For TPC FEC: nnnnn = B2144 (BPSK 21/44), B516
(BPSK 5/16), 21/44 (QPSK 21/44), 3/4 (QPSK 3/4), 7/8
(QPSK 7/8), 17/18 (QPSK 17/18), OQ2144 (OQPSK
21/44), OQ34 (OQPSK 3/4), and OQ78 (OQPSK 7/8),
OQ1718 (OQPSK 17/18), 8P34 (8PSK 3/4), 8P78 (8PSK
7/8), 8P1718 (8PSK 17/18), 16Q34 (16QAM 3/4), 16Q78
(16QAM 7/8).
mmmmm.mmm = Data rate in kHz.
Where: x = A, B, C, D, or V (preset designator).
Note: Setting the modulator rate turns off the RF transmitter.
