Rx
Frequency
RFQ=
10bytes
Command or Query.
Sets or returns Rx Terminal Frequency, in MHz, being received from the
satellite in the form xxxxx.xxxx, where:
xxxxx.xxxx=value from 950.0000 to 65000.0000 MHz (L-Band), in 100 Hz
increments.
NOTES:
1) If RX LO=00000, then the Rx Frequency is entered as L-Band direct –
950.0000 to 2150.0000;
2) If RX LO is set in the range of 30000 to 65000, the Rx Frequency is ±Rx
LO, and this will be the resulting L-Band frequency the modem will expect
to receive.
