Description of arguments
(note that all arguments are ASCII numeric
codes, that is, ASCII codes between 48 and 57)
Response to Command
(target to controller)
Query
(Instruction
Code and
qualifier)
Response to

(target to
controller)
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)
permitted in current mode) command)
Rx
Frequency
RFQ=
8 bytes
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
RFQ= (message ok)
RFQ? (received ok,
but invalid arguments found)
RFQ* (message ok, but not
permitted in current mode)
RFQ? RFQ=xxx.xxxx
(same format as
command
arguments)
Rx Data
Rate
RDR= 8 bytes 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)
RDR= (message ok)
RDR? (received ok,
but invalid arguments found)
RDR* (message ok, but not
permitted in current mode
RDR? RDR=xxxx.xxx
(same format as
command
arguments)
Rx
FEC Type
RFT= 1 byte, value of
1,2,3 or 4
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)
RFT= (message ok)
RFT? (received ok,
but invalid argument found)
RFT* (message ok, but not
permitted in current mode)
RFT? RFT=x
(same format as
command
arguments)
