2.3 Basic Settings
In the MANUAL mode the following values can be entered or altered:
f F (frequency)
f I (modulation mode)
2.3.1 Frequency
Command syntax:
Code: F
Parameter: ................... a
Possible entries / replies
Range: ........................ 0 to 30000000
Stepwidth: .................. 1 Hz
Entry: .......................... in Hz
Note:
The technical data stated in the data sheet are
guaranteed for frequencies as of 10 kHz.
Example 1:
Setting a receive frequency of 21.5 MHz
Command = rAxxF21500000?
Example 2:
Inquiry of the set receive frequency
Command = rAxxF??
Æ Reply = rAxxF21500000?
The VLF>HF receiver is set to a frequency of
21.5!MHz.
2.3.2 Modulation Mode
Command syntax:
Code: I
Parameter: ................... a
Possible entries / replies
15 = L USB
16 = L LSB
17 = L ISB USB
18 = L ISB LSB
The abbreviations for the modulation modes
signify the following:
L USB (B8D, amplitude modulation, moni>
toring sideband = lower sideband,
no USB signal)
L LSB (B8D, amplitude modulation, moni>
toring sideband = upper sideband,
no LSB signal)
L ISB USB (B8D, amplitude modulation, moni>
toring sideband = lower sideband,
LSB and USB signal)
L ISB LSB (B8D, amplitude modulation, moni>
toring sideband = upper sideband,
LSB and USB signal)
Example 1:
Inquiry of the currently active modulation
mode
Command = rAxxI??
Æ Reply = rAxxI18?
The modulation mode L ISB LSB is now active.
Example 2:
Activating modulation mode L USB
Command = rAxxI15?
