Call Sign
Call sign means that the modem transmits its Call sign ID periodically using Morse keying.
Call sign is configured using three settings:
a) Call sign mode sets Call sign operation ON/OFF.
b) Call sign ID defines Morse code to be transmitted, max. sixteen characters, capital letters and
numbers are allowed (lower case letters are converted automatically to uppercase letters).
If Call sign mode is not used (OFF) you can enter e.g. "CALLSIGN" for the Call sign ID.
c) Call sign timer is the interval (1...30 min) between Call sign transmissions.
One Call sign transmission may take several seconds to transmit, depending on the Call sign ID.
Default value: Call sign mode OFF

Channel list
NOTE! Available only in SATEL Proof-TR4+ model. A list of predefined radio channels can be
stored in the memory in order to change the radio settings simply by switching between the
channels. Each channel carries the following info:
•
Channel number (any number -32767...32767)
•
Transmitter/Receiver frequency
•
Channel width (12.5, 20 or 25 kHz)
•
Transmitter power level (optional)
Additionally, the default channel that the radio modem uses after a reset is defined.
Channel lists can be created and utilized by using either SATEL Configuration Manager Software
or SL commands.
SATEL Configuration Manager software provide a channel list editor (snapshot below) for
creating and saving a channel list in the radio modem, or in a file for later usage.
SL commands provide an interface for a host device to command the radio modem directly. An
example of the procedure for creating or replacing a channel list:
1. Clear existing channel list (SL$C=0)
2. Set channel info for each of the channels to be created starting from index 0 (SL$L=)
3. Set number of channels in channel list (SL$C=)
4. Set the default channel (SL$D=)
5. Verify the new configuration:
Get number of channels in channel list (SL$C?)
Get channel info for each of the channels (SL$L?)
Get the default channel (SL$C?)
7. Enable Channel list (SL$M=1) in order to activate the Channel list
8. Save the settings (SL**>)
