Introduction 1.1 The TRP 5000 is a

16、 single side band radiotelephone transmitter receiver combination for duplex, semi-duplex and simplex telephone traffic in the 1.6-4 MHz coastal telephone band and in the maritime mobile short wave bands between 4 and 27.5 MHz. In addition the TRP 5000 provides facilities for radiotelegraph and tele

17、x transmission and reception The TRP 5000 is composed of the T5000transmitter power amplifier, the P 5000 (24 V DC) or the P 5001 (AC) power pack, the E 5000 exciter and the R 5000 receiver. This instruction manual describes the Transmitter Power Amplifier, the Exciter and the Power Packs, while the

18、 Receiver is covered in a separate manual. The transmitter is fully synthesised and provides keyboard selection of up to 256 pre-programmed frequencies, which can be freely distributed in the maritime frequency bands. Silicon transistors and integrated circuits are used throughout except for the tra

19、nsmitter power amplifier stage. These features in conjunction with the fact that no crystal ovens are used enable the transmitter to be ready for operation within 30 seconds after being switched on. The cabinet is a sturdy 19-inch rack construction containing all necessary inter- connections. Becaus

20、e we are constant processing the experience gained during the production and operation of our equipment, it is possible for minor modifications to occur relative to the information given in this instruction manual. Wherever practicable, however, any corrections will be listed on a correction sheet a

21、t the back of the front cover of this manual. 1 - 1 1 - 2 2. Operating Instructions 2.1 Distress Operation on,2182 kHz Set controls as fellows: A SUPPLY to TRANSMIT B C BANDs to 2182 kHz D VOLUME clockwise E SENSITIVITY fully clockwise F MODE to TRANSMIT ALARM G Press and release ALARM START The ala

22、rm signal is now transmitted for approx. 45 seconds and may be monitored in the handset earpiece. When the alarm signal ceases depress handset key and, speaking clearly into microphone, transmit distress message. If it is required to repeat the alarm signal transmission, it Is only necessary to pres

23、s and release the ALARM START push button again. An alarm signal transmission may be interrupted at any time by turning the MODE switch to A3H. NOTE: In the TRANSMIT ALARM mode on 2182 kHz the power output of the transmitter is automatically set to FULL POWER SIMPLEX independent of the setting of th

24、e POWER switch. 2.2 Tuning to 2182 kHz 1. Set SUPPLY switch to TRANSMIT. 30 seconds after switching on the transmitter is ready for operation. 2. Set BAND switch to 2182 kHz.

25、. 3. Press TUNE button and adjust TUNING control for maximum deflection on ANTENNA CURRENT meter. The tuning range on 2182 kHz is reduced so that power is transmitted even when the TUNIN-G control is not adjusted. The transmitter is now ready for operation. NOTE: The type of service used on 2182 kHz

26、 is A3H, simplex. This mode is automatically selected when the BAND switch is set to 2182 kHz, and the MODE switch can therefore be set to any position except TESTALARM. The equipment will also work in the simplex mode even if the POWER switch is in a DUPLEX position. 2 - 1 2.3 Tuning to a Frequency

27、 Other than 2182 kHz 1. Set SUPPLY switch to TRANSMIT. 30 seconds after switching on the transmitter is ready for operation, 2. Set BAND switch to any band except 2182 kHz 3. Turn DIMMER control fully clockwise 4. If FREQUENCY NO display does not show zero, clear display using C key of keyboard. 5.

28、Look up desired frequency in frequency chart and read Frequency -No 6. Key Frequency No. into keyboard. The selected Frequency No. will be displayed. 7. Set BAND switch to position indicated by flashing band indicator lamp. If no flashing occurs the BAND switch is already correctly set. 8. Press TUN

29、E button and adjust TUNING control for maximum deflection on ANTENNA CURRENT meter. 9 Select desired type of service with MODE and POWER switches. Transmitter is now ready for operation NOTE: Transmission is inhibited if the mode setting does not correspond with the frequency selected. On radiotelep

30、hone frequencies the transmitter can be keyed only in the modes A3A, A3J, A3H, and TRANSMIT ALARM. On wireless telegram frequencies the transmitter can be keyed only in the modes Al, A2H, and Fl. 2.4 Operating Controls and their Functions 2.4.1 The SUPPLY switch has four positions OFF Receiver and t

31、ransmitter are switched off. REGEIVE ONLY Power Pack is started up and supplies power to Receiver (and grid bias to transmitter output valves). Remote speaker of receiver is connected to receiver output. STAND BY Power Pack supplies power to Receiver, Exciter, band indicator, and filaments of transm

32、itter output valves. Remote speaker of receiver is connected to receiver output. TRANSMIT Transmitter can be keyed. Remote speaker of receiver is disconnected. NOTE:A built-in delay circuit protects the output valves of the transmitter from being keyed for the first 30 sec. after switching to STAND

33、BY or TRANSMIT. 2 - 2 2.4.2. The POWER switch has six positions LOW POWER SIMPLEX Transmitter is keyed from handset key, morse key, or telex equipment dependent on mode of operation. Receiver is muted while transmitting. Transmitter can be driven to approx. 1/20 Of full output power. MEDIUM POWER SI

34、MPLEX As above, but transmitter can be driven to approx. 1/4 of full output power. FULL POWER SIMPLEX As above, but transmitter can be driven to full power. FULL POWER DUPLEX Transmitter is keyed constantly in the Fl, A3A, A3J, A3H and TRANSMIT ALARM modes (provided the selected frequency is in acco

35、rdance with the mode setting). Receiver is on but built-in speaker is disconnected. In the A2H and Al modes the operation is simplex independent of the setting of the POWER switch. Transmitter can be driven to full output power. MEDIUM POWER DUPLEX As above, but transmitter can be driven to approx.
