Repeaters are devices comprised of both receiver and transmitter
sections, which are used to extend the range of a transmitted signal.
It does this by receiving a weak signal on one channel and retransmitting
the signal (at the same time) on a second channel, at higher power.
The TAC COM 2005 has special features that extend its capabilities for
surveillance operations. These include a phono output for direct
connection from the repeater to a recorder, an optional HOT MIC for full
time audio signal transmissions, and an optional scrambler to encrypt any
of the TAC COM transmitted signals. In addition to receiver and transmit-
ter options, the TAC COM is capable of connecting with an array of
directional and covert antennas through the use of its standard BNC
antenna connector.
WARNING: Never place the repeater with antenna attached in a
closed trunk of a car. You will degrade your range to the extent that
the repeater is useless.
TIP: DTC recommends the use of highly efficient antennas, such as
the ANT-3 Cellular disguise antenna.

DESCRIPTION
The TAC COM 2005 is a portable 2 Watt VHF FM tactical repeater capable
of receiving and transmitting both 12.5 kHz and standard wideband (+25
kHz signals).
Both the receive and transmit frequencies are user-programmable within a
2 MHz range and can be set to any of eight switch selected channels for
both RX and TX. (Programming Kit is optional.) Minimum separation
between receive and transmission frequencies is 3.5 MHz. Programming
cable and software are available as an option. The 2 MHz range and factory
preset 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 and
humidity range. Both transmitter and receiver sections are frequency
synthesized and both are locked to highly stable temperature
compensated crystal oscillators (TCXO’s). The repeater will transmit
continuously for approximately 3 hours on one full charge of the internal
battery.
NOTE: Minimum 3.5 MHz separation between receive and transmit
channels is required. Wider separation between transmit and receive
channels will provide improved performance.
DTC COMMUNICATIONS, INC. 7
NOTE: Do not adjust the
squelch unless you are
experiencing a constant
transmit condition. If that
happens, temporarily switch
to another receive channel.
If the transmit condition
stops, you may be receiving a
third-party transmission on
the original channel.
NOTE: using a wideband
transmitter with a
narrowband receiver setting
will cause some distortion and
loss of some audio.
The typical mission of the repeater is to extend the range of a low power
FM transmitter such as a bodywire. The repeater should remain in
standby mode (not transmitting) until the transmitter is activated. When
the transmitter is keyed ON and in range of the repeater, the repeater will
retransmit the signal on another selected channel. Typically, the repeater
is powered from its own internal rechargeable battery, or via another DC
source such as automotive power. The performance of the TAC COM 2005
is highly dependent on the proper location and
orientation of the antenna.
Is the transmitter that you are using narrowband (12.5 kHz) or is it a
wideband (25 kHz) unit? It is always best to select the bandwidth which
matches the transmitter. If this is unknown, the repeater can receive
either signal in the wideband mode. The TAC COM 2005
bandwidth 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’s
transmit channel also needs to be set to a frequency covered by the
listening post receiver. This is accomplished with the Transmitter
Channel control. The squelch can be set with the control on the main
panel but it normally should not require adjustment.
If you experience the squelch breaking when the bodywire is off, try
another transmitter channel, which is free of interference. Squelch param-
eters can be modified with the Squelch control.
OPERATION
NOTE: To provide easy
narrowband/wideband
selection capability, program
the same frequency on
different channels using the
wide setting on one and the
narrow setting on the other.

Adjustment is not usually needed. If needed, make sure the bodywire
transmitter is OFF. Loosen the locknut and use a small screwdriver to turn
the Squelch control on the TAC COM 2005 counterclockwise until the
Master Power LED turns RED. Then turn the adjustment slightly clockwise
until the LED turns GREEN. Finally test the squelch setting by transmit-
ting with the bodywire and observing the listening post receiver, to make
sure it transmits ON/OFF properly. Retighten the locknut.

TROUBLESHOOTING
Problem Solution
Unit will not turn ON. Check internal battery voltage as read on the panel meter. If less than 11 VDC, recharge the
battery.
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 external
amplifier.
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 bandwidth
operation. This bandwidth must match that of the body-wire transmitter for optimum performance.
Good local audio at the Audio out jack, but
poor 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 and
repeater.
Ensure that there is no interference near the listening post. Try changing frequencies.

TROUBLESHOOTING
Operating Tips
• Put the TAC COM 2005 on the smart charger until the LED on the
smart charger blinks green and orange, or just green to indicate a
full charge. Charge time is 4 to 6 hours. TAC COM should be OFF
for optimum charging.
NOTE: After extended operation, the battery may be hot (Smart
Charger LED green-red flashing). After battery cool down, the
Smart Charger will automatically revert to fast charge (LED solid
red).
• Ensure the body wire transmit frequency is the same as the
selected TAC COM 2005 receive frequency.
• Choose a frequency that is free of interference.
• Energize the bodywire transmitter and the TAC COM 2005. Using
the Audio Out jack on the rear of the TAC COM 2005, you may
connect an external, amplified speaker or recorder to ensure that
the 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 that
the received signal is not strong enough to provide full receiver
quieting. Reposition the ANT-3 Cellular look-alike mobile antenna
with magnetic base to increase signal reception and working
distance.
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 is
fully charged, it will automatically provide power to your TAC COM
2005. Some automobiles have power-off timers on their accessory
power ports, which could otherwise cause a loss of power if the
automobile timed-off off during operation.
• The TAC COM 2005 will continue to broadcast the received audio
signal on the original transmit frequency even if the transmit
frequency is changed at the front panel. This prevents loss of audio
information 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 NOT
activate the TAC COM 2005's scramble feature, as the result will be
a double scrambled signal at the listening post that will not be
readily usable.
