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.
