2 INSTALLATION MECHANICAL HF SSB TRANSMITTER T2130
- When the power has been switched on at the RE2100, the RE2100 detects the existence of possible
slaves.
- When the T2130 has detected an error the T2130 has answered the previous message with the answer
option (C). This results in a synchronized message from the RE2100.
RECEIVER FREQUENCY
Whenever the received frequency has been changed at the RE2100, the frequency is sent to the T2130.
The T2130 ensures that a transformer is switched in at receiver frequencies below 4000 kHz and switched
out at frequencies above 4000 kHz.
KEY
This command is sent continuously to the T2130 when the handset key is activated at the RE2100. The
first time it is sent the command is followed by the actual transmitter frequency and the selected mode
(telex etc.) at the RE2100. The answer is option (A). The following commands are sent without associated
data. There are two different answers depending on the state of the T2130. In both states the T2130 has
the full control of the step attenuator placed in the Exciter Unit (4) in the RE2100.
- State one. Indicates that the T2130 and the AT2110 are NOT ready to transmit.
The answers consist of the answer option (B) associated with an absolute step.
The duration of this state is given by the duration of the automatic power setting and the tuning of the
AT2110.
- State two. The T2130 and the AT2110 are ready to transmit.
The answers consist of the answer option (A) associated with an absolute step.
This state continues until the key is released and the ‘Stop’ command is sent from the RE2100.
TUNE
This command is a subset of the ‘Key’ command. Only state one is performed followed by the ‘Stop’
command. The command is only sent from the RE2100 when the ‘TX’ and ‘Tune’ keys are activated.
DUMMY LOAD KEY
This command is equal to the ‘Key’ command except for the RF output power.
The RF output power is delivered to the AT2110 built-in dummy load instead of the connected aerial.
DUMMY LOAD TUNE
This command is equal to the ‘Tune’ command except for the RF output power.
The RF output power is delivered to the AT2110 built-in dummy load instead of the connected aerial.
STOP TUNE/KEY
This command always terminates the above mentioned 4 variants of the ‘Tune’ and ‘Key’ commands. The
answer is option (A). The command is sent from the RE2100 at one of the following events:
