contact the manufacturer.

9.2.1 Frequency
Command Effect and description of command
SL&FR=nnn.nnnnn Set RX-frequency to nnn.nnnnn MHz
SL&FT=nnn.nnnnn Set TX-frequency to nnn.nnnnn MHz
SL&F=nnn.nnnnn Set both RX&TX-frequency to same nnn.nnnnn MHz
SL&FR? Get RX- frequency (response 'nnn.nnnnn MHz')
SL&FT? Get TX- frequency (response 'nnn.nnnnn MHz')
SL&F? Get RX&TX- frequencies (response TX nnn.nnnnn MHz, RX nnn.nnnnn MHz)
SL&C? Get Reference (Center) frequency (response 'nnn.nnnnn MHz')
SL&C=nnn.nnnnn Set Reference (Center) frequency to nnn.nnnnn MHz
SL&+=nn Set RX&TX- frequency nn channels above reference frequency
Frequency = Reference frequency + nn * Channel spacing, where nn=[0...Number of
channels/2]
SL&-=nn Set RX&TX- frequency nn channels below reference frequency
Frequency = Reference frequency – nn * Channel spacing, where nn=[0…Number of
channels/2]
SL&N? Get current RX&TX- frequency deviation from reference frequency as channels
(Frequency – Center frequency)/Channel spacing (response ‘+nn’ or ‘-nn’)
SL&W? Get channel spacing (response ‘nn.n kHz’)
SL&D=x Set operational mode of the radio. The different values of x are:
”S” = Single Channel
”D” = Dual Channel
”R” = Reverse Dual Channel
Note! Use this command only, if the setup of the frequency bands matches the Dual
Channel operation.
SL&D? Get operational mode of the radio. The response is one of the following:
”S” = Single Channel
”D” = Dual Channel
”R” = Reverse Dual Channel
Note! Use this command only, if the setup of the frequency bands matches the Dual
Channel operation.
