DTC COMMUNICATIONS, INC. 5Repeaters are devices comprised of both receiver and transmittersections, which are used to extend the range of a transmitted signal.It does this by receiving a weak signal on one channel and retransmittingthe signal (at the same time) on a second channel, at higher power.The TAC COM 2005 has special features that extend its capabilities forsurveillance operations. These include a phono output for directconnection from the repeater to a recorder, an optional HOT MIC for fulltime audio signal transmissions, and an optional scrambler to encrypt anyof the  TAC COM transmitted signals. In addition to receiver and transmit-ter options, the TAC COM is capable of connecting with an array ofdirectional and covert antennas through the use of its standard BNCantenna connector.WARNING: Never place the repeater with antenna attached in aclosed trunk of a car. You will degrade your range to the extent thatthe repeater is useless.TIP: DTC recommends the use of highly efficient antennas, such asthe ANT-3 Cellular disguise antenna.DESCRIPTIONDUPLEXERTAC COM 2005 BASE STATIONBODY WORNTRANSMITTERRX TXRXTX
DTC COMMUNICATIONS, INC.6DESCRIPTIONThe TAC COM 2005 is a portable 2 Watt VHF FM tactical repeater capableof receiving and transmitting both 12.5 kHz and standard wideband (+25kHz signals).Both the receive and transmit frequencies are user-programmable within a2 MHz range and can be set to any of eight switch selected channels forboth RX and TX. (Programming Kit is optional.) Minimum separationbetween receive and transmission frequencies is 3.5 MHz. Programmingcable and software are available as an option. The 2 MHz range and factorypreset frequencies are listed on a label on your TAC COM 2005.The TAC COM 2005 repeater is housed in a rugged, water resistant,Pelican case and is designed to operate over a wide temperature andhumidity range. Both transmitter and receiver sections are frequencysynthesized and both are locked to highly stable temperaturecompensated crystal oscillators (TCXO’s). The repeater will transmitcontinuously for approximately 3 hours on one full charge of the internalbattery.NOTE: Minimum 3.5 MHz separation between receive and transmitchannels is required. Wider separation between transmit and receivechannels will provide improved performance.
DTC COMMUNICATIONS, INC. 7NOTE: Do not adjust thesquelch unless you areexperiencing a constanttransmit condition. If thathappens, temporarily switchto another receive channel.If the transmit conditionstops, you may be receiving athird-party transmission onthe original channel.NOTE: using a widebandtransmitter with anarrowband receiver settingwill cause some distortion andloss of some audio.The typical mission of the repeater is to extend the range of a low powerFM transmitter such as a bodywire. The repeater should remain instandby mode (not transmitting) until the transmitter is activated. Whenthe transmitter is keyed ON and in range of the repeater, the repeater willretransmit the signal on another selected channel. Typically, the repeateris powered from its own internal rechargeable battery, or via another DCsource such as automotive power. The performance of the TAC COM 2005is highly dependent on the proper location andorientation of the antenna.Is the transmitter that you are using narrowband (12.5 kHz) or is it awideband (25 kHz) unit? It is always best to select the bandwidth whichmatches the transmitter. If this is unknown, the repeater can receiveeither signal in the wideband mode. The TAC COM 2005bandwidth can be set with the optional software.The repeater’s receiver channel should be set to the transmitter’s(bodywire) frequency using the Receiver Channel control. The repeater’stransmit channel also needs to be set to a frequency covered by thelistening post receiver. This is accomplished with the TransmitterChannel control. The squelch can be set with the control on the mainpanel but it normally should not require adjustment.If you experience the squelch breaking when the bodywire is off, tryanother transmitter channel, which is free of interference. Squelch param-eters can be modified with the Squelch control.OPERATIONNOTE: To provide easynarrowband/widebandselection capability, programthe same frequency ondifferent channels using thewide setting on one and thenarrow setting on the other.

If less than 11 VDC, recharge thebattery.Use an external power source 11 to 16 VDC.Poor local Audio at Audio out jack. Audio out jack is at line level. It will not drive an external speaker without use of an externalamplifier.Check battery and antenna on body wire transmitter.Ensure that body wire transmit frequency and TAC COM 2005 receive frequency are the same.Ensure that the body wire transmitter is in range of repeater.Ensure that the TAC COM 2005 antenna is positioned vertically, or an external antenna is in use.Ensure that an antenna is attached to the antenna jack.Ensure that the squelch adjust has been performed correctly.Ensure that the TAC COM 2005 receiver is programmed correctly for wide/narrow bandwidthoperation. This bandwidth must match that of the body-wire transmitter for optimum performance.Good local audio at the Audio out jack, butpoor or no audio at listening post. Ensure the TAC COM 2005 transmit and listening post receive frequencies are the same.Ensure that the scramble feature is deactivated.Check the listening post's receiver program to ensure that any subaudible coding (i.e. PL code)matches the transmitter, or is turned OFF.Ensure a clear, line-of-sight path with no buildings or mountains between listening post  andrepeater.Ensure that there is no interference near the listening post. Try changing frequencies.
DTC COMMUNICATIONS, INC. 11TROUBLESHOOTINGOperating Tips• Put the TAC COM 2005 on the smart charger until the LED on thesmart charger blinks green and orange, or just green to indicate afull charge. Charge time is 4 to 6 hours. TAC COM should be OFFfor optimum charging.   NOTE:  After extended operation, the battery may be hot (SmartCharger LED green-red flashing). After battery cool down, theSmart Charger will automatically revert to fast charge (LED solidred).• Ensure the body wire transmit frequency is the same as theselected TAC COM 2005 receive frequency.• Choose a frequency that is free of interference.• Energize the bodywire transmitter and the TAC COM 2005. Usingthe Audio Out jack on the rear of the TAC COM 2005, you mayconnect an external, amplified speaker or recorder to ensure thatthe TAC COM 2005 is receiving the body wire transmitted signal.• The LED will occasionally begin to flicker between green and red,sometimes appearing yellow or orange. This is an indication thatthe received signal is not strong enough to provide full receiverquieting. Reposition the ANT-3 Cellular look-alike mobile antennawith magnetic base to increase signal reception and workingdistance.Operating Tips• The TAC COM 2005 can be powered with an AC to DC converter,or an automotive accessory power cord. If the internal battery isfully charged, it will automatically provide power to your TAC COM2005. Some automobiles have power-off timers on their accessorypower ports, which could otherwise cause a loss of power if theautomobile timed-off off during operation.• The TAC COM 2005 will continue to broadcast the received audiosignal on the original transmit frequency even if the transmitfrequency is changed at the front panel. This prevents loss of audioinformation during the mission if the channel knob is moved.To change the channel during transmission:• Turn OFF the body wire transmitter, or• Turn OFF the TAC COM 2005, change the    channel, and restore power. • If using the body-wire with scramble option enabled, DO NOTactivate the TAC COM 2005's scramble feature, as the result will bea double scrambled signal at the listening post that will not bereadily usable.
