The manual DV17900.03 “Installation and Operation” contains the following sections: Section Installation and Operation Maintenance and DV17900.03-BAI Repair DV17900.04-BAI General Information Installation Operation Theory of Operation Maintenance and Repair Parts List Modification and Changes Circuit Diagrams For safe operation of the VHF Ground Station TG660, follow the instructions below: Stay always in a sufficient distance to the antenna avoiding been exposed to higher RF radiation during TX operation. Perform a voice communication test before start-up. This test might be positive, if carried out close to the corresponding radio-station, even if the antenna cable is broken or short-circuited. It will not be possible to establish communication over a distance of 5 to 10 km in this case. Speak loud to the microphone and keep it always close to the lips, otherwise ambient noise can be intrusive and make understanding difficult. Use only microphones or headsets, which are suitable for ground-stations. Incoming radiation on the equipment antenna can affect the integrated amplifier of the microphone (feedback). This is noticeable in the station by whistling and/or heavy distortion. The described disturbances can occur in different ways on different transmit channels. Transmit buttons can stick, or TX line is short circuited thus causing continuous carrier signal on the active channel. Therefore ensure that the display (sign “”) disappeared when the “TX” button was released. WARNING 1.2 The TG660 connects to High Voltage power supply! Only qualified personnel shall perform installation work. Always disconnect mains cable before gaining access to the inside of the TG660. Purpose of Equipment The TG660 is a fixed station for voice communications in the VHF frequency range of 118.000 MHz to 136.990 MHz with 25 kHz / 8.33 kHz channel spacing in the standard version. The transceiver TG660, designed for ATC operations, is useable on airports with different scale as a main transceiver, or as a standby unit, as well as for special tasks within the scope of air traffic control. _____________________________________________________________________________________________ DV 17900.03-BAI Issue 2 03/2016 Page 1 TG660-(XX) 1.3 General System Description The VHF transceiver TG660 specially designed for mounting in 19-inch rack systems, or in an ATC desk. The unit operates in an AC supply voltage range from 100 V...230 V ± 10% / 50...60 Hz or with 24 VDC, +20% - 10%. The TG660 power supply logic is operating with AC-power by default. After AC-power failed, the logic automatically switches over to DC-power. The moment AC-power becomes available the logic returns back to AC-power source. An optional internal 12 VDC battery inside the TG660, if installed, provide power to continue operation over a certain time if AC and DC supply voltage fail at the same time. Depending on the version, the TG660s are capable of delivering up to 6W, 10W, 25W or 50W RF power output (RF-carrier) to an external antenna via a 50Ω coaxial RF-cable. The station has a simple user-friendly HMI; the main components on its front panel are the 2-line 16 character liquid-crystal display (LCD) and several control elements (rotating knob and buttons). The selected frequency and operating status of the equipment, displayed on the LCD, inform about the current operating mode. Control elements (knob, buttons) enable the user to change operating modes or operating frequency. Standby switch selected to “Standby” partially shuts down the TG660 internal power supply. Some circuitry of the power supply continue listening to the “Standby Switch” to repower the unit at any time. The “ON/OFF” switch, located on the rear panel, disconnects from AC supply completely. Fig. 1 - 1 Front side The VHF transceiver TG660 is available in a 6W, 10W, 25W or 50W transmit power version. An antenna mismatch of ≥ 4:1, detected on the transmitter output terminal, cause automatic output power reduction to 40 % of the declared nominal TX power. The VHF transceiver is protected against jammed transmit button or short circuit on the PTT line. Factory setting of the time limit to release a “stuck PTT” is 2 minutes. _________________________________________________________________________________________________ Page 2 DV 17900.03-BAI Issue 2 03/2016 TG660-(XX) 1.3.1 Microphone Inputs Several microphone inputs are available for the following types: Standard microphone unbalanced, DC coupled and providing power supply for the mike, Dynamic mike input balanced and Symmetrical line input. These microphone inputs connect to a dynamic volume compressor inside of the remote controlled transceiver, which keeps the modulation voltage constant ≥ 80% over a wide mike-signal input voltage range. 1.3.2 Audio outputs The TG660 has four different outputs: Headphone output Speaker output (speaker is switched off in transmit mode) Line out Voice recorder The headphone output level provide 100mW @ 600Ω. The rated loudspeaker output power is ≥ 4W sin @ 4Ω. The LINE_OUT – AF output nominal output level is zero (0) dBm @ 600Ω. The levels on headphone and speaker output are adjustable by means of the volume potentiometer within the range -20...+10 dBm. The voice recorder output level is – 6 dBm @ 600Ω balanced. 1.3.3 Side tone output In transmit mode, the side tone signal is routed to the line and phone output. 1.3.4 TG660 internal Sub Modules The “Control Board”, located behind the front panel of the TG660, consists of the LC Display and all the Human Machine Interface (HMI) (e.g. Keypad, Function Switches and the Volume Control). All changes made from the “Control Board“ are transferred to the “Interface Board” on which a microcontroller exchanges control information with the remote control transceiver like change of frequency, volume adjustment, “SQL” on/off and other parameters of the equipment. The microcontroller on the “Interface Board” handles the serial communication interfaces and by means of a Remote Control Unit which provide all settings of operating parameters on the VHF transceiver TG660. (Web Browser via IP) The loudspeaker, located behind the front panel, switch off automatically during TX. This avoids acoustic coupling between loudspeaker and the microphone, which can cause acoustical feedback. The RF power amplifier is located in the center of the chassis behind the front panel. The PA3-2AB-AIR-1 model is a mobile Air Band AM VHF RF power amplifier which can deliver 25 watts or 50 watt (depending on the TG660-(XX) version) of RF power when driven with 8/10 watts and it will cover the frequency range from 118 - 138 MHz. The amplifier’s dimensions are: 7.5”L x 2.2”H x 3.7”W. _____________________________________________________________________________________________ DV 17900.03-BAI Issue 2 03/2016 Page 3 TG660-(XX) 1.3.5 Rear panel Following items are on the rear panel of the transceiver TG660 mounted.

The Logo ” Becker Avionics” appear for 2 seconds on the LC display. Depending on which power source is available, the associated indication at the front panel light up, (LED “AC” and/or “DC”). The TG660 power supply logic is operating with AC-power by default. After AC-power failed, the logic automatically switches over to DC-power. The moment AC-power becomes available the logic returns back to AC-power source. An optional internal 24 VDC battery inside the TG660, if installed, could provide power for continued operation over a certain time if AC and DC supply voltage would fail the same time. If the station switches from AC to DC-power or vice-versa, the station is operable with the same functions and settings as before. 3.2.2 Power on Built In Test (PBIT) Right after power is applied, the system performs a Display dimming test from minimum to maximum brightness and thereafter the LCD shows “Becker Avionics and TG 660” for approximately two (2) seconds. st PBIT thereafter starts in a 2 seconds interval to change from the 1 test-step to the next up to the last one. 1.
