Part 1 is valid for a Vbattery < 26.5 Volt and has the following equation: Vf_max1 = 0.33 * Vbattery + 0.20 (Volt) Part 2 is valid for a Vbattery >= 26.5 Volt and has the following equation: Vf_max1 = 9.00 (Volt) Vbattery is measured by the TX-processor.
2 INSTALLATION MECHANICAL HF SSB TRANSMITTER T2130 2.3.3.3 TUNING THE AT2110 The tuning may take place in 3 different procedures: Uptune, where a tuning is done from basic data. Retune, where the tuning is done from data saved at the latest Uptune. No tune, which is done when there is no AT2110 in the system (jumper 5 is inserted).

3 SERVICE T2130 3.4 TROUBLE SHOOTING SAILOR Compact HF SSB system has built-in self-diagnostic service system, which is a great help in locating a fault. When a fault is detected an error message will be displayed in the RE2100 display.
Page 57
3 SERVICE T2130 If the 16 Volt is ok: The error is probably in the AT2110: Check the connection to the tune motor MO1 in AT2110. Check the ‘Motor +’ connection between the T2130 and the AT2110. If the 16 Volt is NOT present: The error is probably in the T2130: Check the connection between the TX-processor (3) and the Connection Board (6) in T2130.

The cable terminations (jumper P04) must be removed when the external RD232C is to transmit on the SP-Bus. SERIAL DEVICE BUS DRIVER &...

5 CIRCUIT DESCRIPTION AND SCHEMATIC DIAGRAMS T2130 When measuring a voltage, the Vref (pin 9) is at +5.0 Volt. The reference diode D14 (LM385) gives +2.5 Volt. The analog switch U15/3 (MC14053) is controlled by the serial device selector and connects the 2.5 Volt reference to the non-inverting input of the op-amp.

5 CIRCUIT DESCRIPTION AND SCHEMATIC DIAGRAMS T2130 Figure 6: Measuring RHO 26043 4/9 When measuring RHO the Vforward is connected to reference input of the ADC (U17, pin 9). Vreverse is connected to pin 4. The result of the rathiometric measuring is the parameter RHO, defined by Vreverse divided by Vforward.

5 CIRCUIT DESCRIPTION AND SCHEMATIC DIAGRAMS T2130 TUNE MOTOR CONTROL The main functions of this circuit are to control the motor MO1 in the AT2110 at two speeds, high and low, and detect when the variable capacitor has rotated one half turn. The speed of the motor is selected from the microprocessor via the serial device bus and the shift register U14 (74HC595).

5 CIRCUIT DESCRIPTION AND SCHEMATIC DIAGRAMS T2130 The analog switch U15/2 which is controlled by the microprocessor via the serial device bus and the shift register U14 and the driver U09/3 switches between the AE-current and the Vforward. AE-current comes in from the AT2110 to the TX-processor in P05, pin 3 and is divided by the resistors R42 and R44.
