Change receiver IF bandwidth. nnnn is a two to four digit number that
represents the IF bandwidth in units of 10 Hz. (e.g. for an IF bandwidth of
2700 Hz, nnnn is replaced with the digits 270). The selected bandwidth
must be on the list of available bandwidths below. The range is limited
under certain conditions. In ISB mode the bandwidth is fixed and need
not be sent. For all other modes other than AM and FM, the maximum
bandwidth is limited to 6 kHz.
The following is a list of bandwidths available in the CDR-3250 receiver
(all bandwidths are in Hertz):
100 800 2100 3400
150 900 2200 3500
200 1000 2300 4000
250 1100 2400 5000
300 1200 2500 6000
350 1300 2600 7000
400 1400 2700 8000
450 1500 2800 9000
500 1600 2900 10000
550 1700 3000 12000

Request current IF Bandwidth.
X*
Switch between local and remote control operation (serial interface only).
The * is replaced with the character 0 to enable the receiver front panel
and disable all remote change parameter commands (except this command
and the V* command), or the character 1 to enable all remote control
commands and disable all front panel keypad input (except the LOC/REM
key). The receiver front panel may always override the remote controller
by pressing the LOC/REM key until the display shows LOCAL). The
power on default state is X1.
X? Xab
Request remote control status (serial interface only): The letter a is
replaced with a 1 to signify that remote control is enabled from the remote
controller or a 0 to signify that remote control has been disabled from the
remote controller, and the letter b is replaced by a 1 to indicate that
remote control operation has been selected from the receiver front panel
or a 0 to signify that remote control operation has been disabled from the
receiver front panel. For the receiver to respond to change parameter
commands from the remote controller, both the remote controller and the
front panel selections must be enabled (receiver replies X11 to X?).
