Rx
RFQ=
8 bytes
Frequency
Rx Data
RDR=
8 bytes

Rx
RFT=
1 byte, value of
1,2,3 or 4
FEC Type
Description of arguments
(note that all arguments are ASCII numeric
codes, that is, ASCII codes between 48 and 57)
2 = Off due to ext H/W Tx Carrier Off command
(not a valid argument when used as a command)
All other codes invalid.
Example: TXO=1 (which is Tx Carrier On)
Command or Query.
Rx Frequency, 52 MHz to 88 MHz, (70 MHz band)
or 104 MHz to 176 MHz (140 MHz band).
Resolution = 100 Hz.
Example: RFQ=143.4567 (which is 143.4567 MHz)
Note: Querying 'Options Fitted' (using EID?) will
indicate if the unit is 70 MHz or 140 MHz IF band
Command or Query.
Rx Data rate, in bps, between 2.4 kbps and 2048
kbps. Resolution = 1 bps.
Example: RDR=002.400 (which is 2.4 kbps)
Command or Query.
Rx FEC decoding type, where:
0 = None (uncoded - no FEC)
1 = Viterbi
2 = Sequential
3 = Viterbi + Reed-Solomon
4 = Sequential + Reed-Solomon
5 = Rate 3/4 QPSK Turbo (S/W Version < 1.15)
6 = Rate 21/44 BPSK Turbo (S/W Version > 1.14)
7 = Rate 5/16 BPSK Turbo (S/W Version > 1.14)
All other codes invalid.
Example: RFT=1 (which is Viterbi coding)
