CDR500 Wall Mount Repeater Station
Overview
This section contains information about the perfor-
mance of the CDR500 Wall Mount Repeater Station, the
basic assembly and disassembly. The steps for tuning
the duplexer can be found in Section 5 of this manual.
Performance
The CDR500 repeater is not a high performance
repeater, but it is designed to withstand constant use. It
was designed and tested with the Professional Series
mobile radios. The CDR500 repeater package is
designed for fixed locations where protection from the
elements (snow, rain, etc.) can be provided. The
repeater station is intended for permanent wall or rack
mounting. (The rack mounting requires the optional
HLN9169 mounting plate).
The fan is single speed to provide maximum cooling at
elevated ambient temperatures and 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.
Provision has been made for mounting a receiver pre-
selector (optional) inside the CDR500 repeater hous-
ing. The preselector increases the interference rejection
of the receive radio to strong signals several MHz away
from the desired receive channel.

ware (Bags 1 and 2) for assembling your repeater.

Additional Kits You May Require
In addition to the CDR500 repeater housing kit
(HKLN4060), you may need some of the following
units or optional kits.
Professional Series Transceiver
Almost any of the Professional Series radios 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 HPN9005 or
HKPN4001 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 n a relatively inaccessi-
ble location.
