Introduction
The Wulfsberg C-5000 Communication Management Controller (CMC) is a microprocessor-based control
head device that controls one or two Wulfsberg transceivers. The C-5000 supports the full line of
Wulfsberg FLITECOMM, FLEXCOMM I, and FLEXCOMM II transceivers. This manual is intended to
quickly instruct the user on the basic operations of the C-5000 and also outline the advanced operations
that set the C-5000 apart from any other communication device.
Features
The C-5000 provides a host of powerful features, including
Controls Wulfsberg RT-5000, RT-406F, RT-450, RT-138(F), RT-30, RT-118, RT-9600(F) and
RT-7200 transceivers.
700 preset channels, programmable from the front panel or using Wulfsberg’s Remote Programmer
software.
Users can dial in frequencies, PL tones, and transmit power on two “manual” channels.
Advanced multi-radio modes, such as Simulcast, Relay, Repeater, and Relay-Simulcast.
Control encryption functions embedded in the RT-5000 transceiver such as P25 Digital Modulation
and encryption with Over the Air Rekey (OTAR) capability.
Transceiver Overview
The C-5000 provides support for the Wulfsberg FLITECOMM, FLEXCOMM I, and FLEXCOMM II
transceivers. It is very important that users know the number and type of transceivers connected to the
C-5000, since different transceivers have very different capabilities and features. Here is a summary of
the supported transceivers and their capabilities.
FLEXCOMM II
This product line consists of the RT-5000 AM/FM transceivers, which cover the 29.7 to 960 MHz
frequency range. The optional Guard Receiver can be specified as a single channel crystal guard
(available in three frequency ranges), a tunable multi-channel guard (29.7 – 960 MHz), or a multi-band
digital-capable guard (available in four frequency ranges). RT-5000’s are equipped with CTCSS and
DCS tones on both the Main and Guard Receivers. The MTM (digital-capable) Guard variant of the RT-
5000 adds support for P25 and Trunking channels, with encryption and over-the-air-rekey (OTAR)
capability.
FLEXCOM I
This product line currently consists of the RT-30, RT-138F, and RT-406F transceivers. The C-5000 also
supports the RT-118, RT-138, and RT-450 transceivers, which are no longer manufactured but remain in
wide use. The RT-30, RT-138F, and RT-406F FM transceivers cover the 29.7 to 49.99 MHz, 138.0 to
173.9975 MHz, and 406.0 to 511.9975 MHz frequency ranges, respectively. These transceivers can be
specified with a single-channel, crystal-controlled, Guard Receiver that operates on a customer-specified
frequency. An optional Guard Receiver CTCSS decoder with programmable Guard Receiver tone can
also be specified.
FLITECOMM
This product line is no longer manufactured, but remains in wide use. It consisted of the RT-7200, RT-
9600, and RT-9600F transceivers. They were available with a two-channel, crystal-controlled, Guard
Receiver that could be user-specified for any Guard frequency between 138.000 and 173.9950 MHz (RT-
7200) or between 150.000 and 173.9975 MHz (RT-9600/9600F). They were equipped with CTCSS tones
on both the Main and Guard Receivers.

Using the Direct/Repeat Feature
The C-5000 supports both direct and repeat modes of operation. Any preset channel that has identical
transmit and receive frequencies is considered a direct channel. If the transmit and receive frequencies
are different, the C-5000 considers the channel a repeater channel. Repeater channels can be
temporarily changed into direct channels by pressing the DIR button. This will temporarily copy the
receive frequency into the transmit frequency, and the direct mode indicator will light. The following
illustration shows radio 1 in direct mode.

Using the Edit Page
The EDIT PAGE allows the operator to temporarily change properties of a preset channel, and
permanently change properties of a manual channel. Precisely which properties can be changed varies
with channel and radio type. For example, transmit power can only be changed on RT-5000 radios,
because the other radios do not have variable power capability. The following illustration is an example
of what the EDIT PAGE looks like. Your C-5000’s display may appear differently depending on the
currently selected channel and its associated properties.

Changing PL and DPL (CTCSS and DCS) Tones
The C-5000 supports both CTCSS (PL) and DCS (DPL) tones. The tone used by a channel can be
temporarily overridden on the EDIT PAGE. You can select any valid tone, or turn tones off. (Channels
programmed to use the ITM of an MTM Guard receiver module in an RT-5000 cannot be changed)
Turning Tones Off
Move the cursor under the “T” of the receive tone field, as depicted below.

Changing Transmit Power
The C-5000 supports the selection of high and low transmit power. Normally high power is used,
however, if interference or other transmit issues are experienced, low power may be selected to help
remedy the issue. If you have a radio that supports multiple power levels, such as the RT-5000, you can
alter the power setting from the EDIT PAGE as follows.
Move the cursor under the transmit power field, as depicted below.

The modulation type can only be changed on the manual channel, and can only toggle between AM and
FM. To change the manual channel’s modulation type, do the following.
Move the cursor under the modulation field, as depicted below.
Rotate the VALUE knob clockwise once. The modulation indicator will toggle between AM and FM.
(118-136 MHz and 225-400 MHz are normally AM frequencies. All other frequencies are usually
FM)
