TBR-142 Artillery Communication System

I wrote a blog 10 years ago about TBR-142 (I), it seems that it is time to update my knowledge.  TBR-142 Artillery Communication System was developed as part of the ZXY88-200 Artillery Command and Control System in early 90’s and it functions as the communication section of the system.  It also could work independently as communication devices for artillery units.  The system mainly consists TBR-142(I) VHF Transceiver, TBR-142(II) Commanding Device, TBR-142(IIID) Multifunction telephone and TBR-142(IIIG) Control Unit for Anti-Aircraft Artillery system.  The system works as this:  

(1) When works independently:

For gunner, the system consists a TBR-142(I) VHF transceiver and a TBR-142(IIID) multifunction telephone.  

For commander, the System consist a TBR-142(II) Commanding Device which is commander’s multifunction telephone and a transceiver (either a TBR-142(I), or a TBR120 VHF transceiver).

(2) When works within ZXY88-200 Artillery Command and Control System:

   In ground artillery system:

• For Gunner, in addition to TBR-142(I) VHF transceiver and a TBR-142(IIID) multifunction telephone, there is a Gunner’s data console come from ZXY88-200 system.  This device is connected to the TBR-142(IIID) multifunction telephone and display data sent from commander. 
• For the commander, the TBR-142(II) Commander’s multifunction telephone and transceiver are connected to ZXY88-200 as the communication device.

   In Anti-Aircraft Artillery system:

• For Gunner, in addition to TBR-142(I) VHF transceiver and a TBR-142(IIID) multifunction telephone, there is a TBR-142(IIIG) device which connect the TBR-142(IIID) and the anti-aircraft artillery piece and control the gun’s aiming and firing.

What I have here is a gunner’s unit.  It consists a TBR-142(I) VHF transceiver, a TBR-142(IIID) multifunction telephone, a TBR-142 (IIID) speaker plus two antennas, handset, headset and some other accessories, all are carried by a plastic box.

TBR-142(I) VHF FM transceiver (code name 865-1):

The TBR-142 (I) is a channel-based VHF FM transceiver.  It could work alone or connected to a TBR-142 (IIID) as the wireless portion of the gunner’s communication unit.  The radio works within 40.000 to 59.975MHz with output power of 1 Watt or 0.3 Watt selectable. It is powered by a 12V Ni-Ca rechargeable battery unit or external 12V DC power source like a vehicle battery.  It measures 217x135x58, and weight about 2.7 kg with battery, antenna and headset.  It has a three-level voice volume control with squelch mode. There are three antennas: a 1.3-meter whip antenna, a 0.3-meter short antenna and a 10-meter wire antenna.  When using 0.3-meter short antenna, the communication distance over a flat terrain is about 500 meters; and when using 1.3-meter whip antenna, the communication distance is about 2 km.

TBR-142(IIID) Multifunction Telephone (code name 865-3D):

TBR-142(IIID) is a multifunction telephone.  It could work alone as a field telephone; or it could be connected to a TBR-142 (I) radio form a gunner’s communication unit; and it also could be connected to a gunner’s data console or a TBR-142(IIIG) device and works as a communication section within ZXY88-200 Artillery Command and Control System.

TBR-142(IIID) has the same dimension as that of TBR-142 (I) and weights about the same as that of TBR-142 (I).  Same as that of 865-1, it is powered by a 12V Ni-Ca rechargeable battery or external 12V DC power source.  The TBR-142 (IIID) Speaker is part of the 865-3D.
