Overview

This section contains information about the perfor-
mance, basic disassembly and assembly of the CDR700
Desktop Repeater Station.

Performance

The CDR700 repeater is not a high performance
repeater, but it is designed to withstand constant use. It
was designed and tested with Professional Series
mobile radios. The CDR700 repeater package is
designed for fixed locations where protection from the
elements (snow, rain, etc.) can be provided. The station
is relatively light and portable.
The fan is controlled by a thermal switch connected to
the power supply. This switching minimizes noise in
office environments while providing maximum cool-
ing at elevated ambient temperatures or during heavy
transmit duty cycles. The station is defined as intermit-
tent transmit duty cycle, but it may have a surprisingly
lower power slump when keyed for long periods in an
office or shop environment.
The Professional Series mobile radios may be pro-
grammed as "transmit only" as well as "receive only"
mode of operation.

Additional Kits You May Require

In addition to the CDR700 repeater housing kit
(HKLN4056), you may need some of the following
units or optional kits.

Professional Series Transceiver

Almost any of the Professional Series radio may be
used in the receive radio and transmit radio functions.
This applies to both uni-directional and bi-directional
repeater configurations. Be aware of any local regula-
tory requirements when choosing the model(s).
If a lowband repeater is being configured, it may be
necessary to reduce the output power to remain within
the 15 Ampere current rating of the HPN9033 Power
Supply.

HKKN4000 Power Sense Cable

Adding ignition sense to the receive and transmit
radios with the HKKN4000 Power Sense Cable and
programming the radios for ignition sensing operation
will ensure that the repeater automatically powers up
whenever power is applied. This is particularly impor-
tant if the repeater is mounted in a relatively inaccessi-
ble location.

HKKN4001 External Duplexer Cable Kit

The two (2) RF cables in this kit provide connection
between the mini-UHF RF antenna connectors on the
Professional Series transceivers and type-N bulkhead
female connectors that mount on the back panel of the
CDR700 repeater housing. Use this kit if the repeater
