FSK
–
Frequency-Shift Keying *
The FSK is a frequency modulation scheme in which digital information is transmitted through discrete frequency
changes of a carrier wave. Data is sent at the beginning of each hour. To use FSK, set the four following parameters:
•
identification (CONF.FSK.ID): call sign to transmit in Morse code, character string
–
empty by default.
•
number of repetition (CONF.FSK.REP) from 0 to 255
–
0 by default.
•
frequency shift (CONF.FSK.SHIFT) in kHz from 5 to 25 and -25 to -5
–
10 by default.
•
speed of transmission (CONF.FSK.SPEED) in WPM from 0 to 25
–
5 by default.
5.14.
Stereo Encoder parameters
These parameters are available as:
Front panel
Stereo Encoder menu
see section 6.3.13
Serial commands
CODER and CONF
see sections 7.2.7 and 7.2.4
Embedded web site
Transmitter/Modulation pages
see section 8.4.3
MO/ST
(CODER.MOST)
–
read/write
With this parameter, set the stereo generator in mono or stereo mode. For mono, there are 3 options: Left channel
broadcast in mono (Mono_L), right channel broadcast in mono (Mono_R), the sum Left+Right broadcast in mono
(Mono). Otherwise left and right channels are broadcasted in stereo.
STEREO, MONO, MONO_L or MONO_R
CURRENT AUDIO
(CODER.SELECT.AUDIO)
–
read only
This parameter indicates the channel used by the modulator for the audio, as set with the INPUT.SELECT menu.
NONE, AUTO, LINE1, LINE2, MPX1, MPX2, PLAYER or GENE
19kH PHASE
(CONF.PHASE.PILOT)
–
read/write
With this parameter, set the pilot sub-carrier phase. We recommend setting it at 0°.
De -180 à +180°
19k OUTPUT LEVEL
(CODER.19KOUT.LEVEL)
–
read/write
With this parameter, enable/disable the rear panel 19 kHz clock and set its output level. 0=off; between 1 and 7: set a
level between 0.9 and 1.1 V peak-to-peak. 5 corresponds to 1 V.
From 0 to 8 V
