OPERATOR’S MANUAL
1. Introduction
The Wulfsberg "2000" family of Flexcomm products are comprised of the P-2000 panel mount transceiver
and the RT-2000 remote mount transceiver which is controlled by the C-2000 control head. The P-2000
and RT-2000 are capable of being populated with one or two ITM's (Internal Transceiver Modules)
covering any combination of the following frequency bands: VHF (137-174 MHz) UHF -1 (403-470 MHz or
380-470 MHz), UHF -2 (450-520 MHz) and 800 (806-870 MHz or 764-870 MHz). For applications where
multiple points of user operation are required, one or more C-2000's can be added.
For purposes of this manual the term "P-2000" shall be used to describe a P-2000 or C-2000/RT-2000
installation. In both systems, the features and user interface is identical.
A. Features
The P-2000 provides a host of powerful features, including:
Multi-band operations: One or Two ITM's covering any combination of the following
frequency bands:
137 - 174 MHz (10/1 Watt Transmit Power)
403 - 470 MHz or 380-470 MHz (10/1 Watt Transmit Power)
450 - 520 MHz (10/1 Watt Transmit Power)
806 - 870 MHz or 764-870 MHz (3/1 Watt Transmit Power)
(1) Clear and bright Color LCD display showing Active/Standby channel selection along with
other critical operational information.
(2) 255 Preset channel memory in each internal transceiver module.
(3) The powerful yet incredibly simple user interface that allows the user to select channels
using the firm tactile feedback keypad or rotary knobs.
(4) Modulation types available in the P-2000 include FM analog, P25 Digital conventional, P25
Trunking and Motorola 3600 Baud Trunking. Transceivers are capable of operating on 12.5
kHz, 20.0 kHz, and 25.0 kHz channels depending on options.
(5) Multiple types of encryption are available as options (AES, DES, DES-XL, DES-OFB, DVP
and DVI). In addition, MDC1200 OTAR and P25 OTAR are standard in all models that
include encryption capability.
(6) One or Two microphone/headset interfaces are supported. This provides retrofit
applications the ability to use both transceivers even if only one microphone/headset port is
available on the aircraft audio panel system. If two microphone/headset ports are used, the
P-2000 is capable of independent operation of each ITM. In other words, one user can be
operating on FM1 while the other user independently uses FM2.
(7) Advanced multi-radio modes, such as Relay, Simulcast and Relay-Simulcast.

B. Transceiver Overview
The Wulfsberg 2000 family of radio products are FM Tactical transceivers that incorporate one or two
transceiver modules and control functions into a single panel mount unit (P-2000) or a panel mount
control head (C-2000) and remote mount RT-2000 Transceiver. Part number variations of the unit
exist for any combination of the following frequency bands: 137-174 MHz, 403-470 MHz or 380-470
MHz, 450-520 MHz, and 806-870 MHz or 764-870 MHz. Each transceiver module with the exception
of the 806-870 MHz or 764-870 MHz band can transmit with 1 or 10 Watts transmit power. The 800
MHz unit produces 1 and 2.75 watts transmit power. The P-2000 can operate by itself or in
conjunction with the C-2000 control display acting as a remote slave control. Input voltage is 28 volts
DC and the keypad is backlit from either 28VDC, 5 VDC or 5 VRMS AC.
The Wulfsberg C-2000 is a control display unit that can be used as a slave control head with a P-
2000 panel mount transceiver, or as a primary or slave control head for the RT- 2000 remote
transceiver. Versions of the C-2000 include black faceplate and options for either Standard or NVG
compatible displays. Input voltage is 28 volts DC and the keypad is backlit from either 28 VDC, 5
VDC or 5 VRMS.
The Wulfsberg RT-2000 is a remote mounted transceiver that incorporates one or two transceiver
modules in a remote mounted unit. It must be controlled by at least one C-2000 control head.
Additional C-2000's can be added to the system for multi-positional control of the transceiver. Part
number variations of the unit exist for any combination of the following frequency bands: 137-174
MHz, 403-470 MHz or 380-470 MHz, 450-520 MHz, and 806-870 MHz or 764-870 MHz. Each
transceiver module with the exception of the 806-870 MHz or 764-870 MHz band can transmit with 1
or 10 Watts transmit power. The 800 MHz unit produces 1 and 2.75 watts transmit power.
Operationally a P-2000 or C-2000/RT-2000 system operates identically with the exception of the
PC/Keyloading interface. For a P-2000 the interface is located on the front of the P-2000. In a C-
2000/RT-2000 system, the connector on the RT-2000 is used for PC/Keyloading functions. The
connector on the C-2000 is not currently used.

C. The Home Page
The HOME PAGE is the primary operational page of the P-2000. The HOME PAGE becomes visible
when the P-2000 is ready for user input, immediately after the power up and initialization sequences
have completed. When viewing the HOME PAGE, Radio 1 (Also called FM1 or transceiver #1) is
always displayed on the top section. Radio 2 is always displayed on the bottom section. All keypad-
initiated operations are performed on the active radio. The active radio is easily distinguished by the
bright blue color. The cursor is the square box that is located either around the channel number or
around the channel alpha identifier. It can be quickly toggled between the channel number and alpha
identifier using the cursor knob.
The following illustration is an example of what the HOME PAGE looks like.
The home page is divided into 3 areas – FM 1 information (top), FM 2 information (middle), and an
area for system status or system prompts (bottom). In the picture above notice that the area in blue
contains the information for FM 1. FM 1 will always be on the top. The names “FM1”, “FM2” can be
changed in the system setup so that users can change it to something more meaningful like “VHF”, or
“MAIN”.
(1) ACT/SBY - The normal operating mode of the P-2000 is very similar to most ATC
COMM radios. The user tunes the Standby channel and then “Flip-flops” it into the Active
channel position using the TRANSFER button. The radio is loaded with Active channel.
The standby channel is ONLY used as a scratchpad for selecting the next channel.
As an alternative to using the ACTIVE/STANDBY mode, the operator can press and hold
the transfer button for 3 seconds and the STANDBY channel will disappear and now the
user can tune the active channel directly. Either mode can be selected in the System Setup
Mode as the default mode of operation.
Notice the square box (CURSOR) around the SBY channel number 104. This indicates
the system will tune the Standby channel number. The cursor can be moved around the
alpha identifier and channels will be selected alphabetically using the Alpha Identifier.

G. Selecting a Standby Channel Using the Cursor/Value Knob
When the P-2000 first powers on, the selected channels will be set to those that were active when
the unit was powered down. To select a different preset channel, do the following:
(1) Using the cursor knob, put the square cursor around the channel number. Turn the value
knob until the channel is your desired channel. If you wish to make this your active channel,
push the transfer button.
H. Selecting a Channel Using the Keypad
Occasionally, it is desirable to select a preset channel by entering its number via the keypad, rather
than dialing it in with the cursor/value knobs. This can be performed as follows.
(1) When the user presses the CHAN key, the keypad channel entry mode will begin. This
mode allows the user to tune a channel by inputting the desired channel’s number into a
field via the keypad. The figure below depicts this mode of channel tuning. If no keypad
input is received for more than 4 seconds, the operation will automatically cancel. If the
user presses the HOME key, the operation will also cancel. When the user presses the
ENTER key, the channel with the number input into the field will be loaded. If the input
channel number is invalid, an error tone will sound, “INVALID CHANNEL” will be displayed
in lower field, and the previous “good” channel will be reinstated.

I. Selecting a Channel by Alphanumeric Identifier
To change the standby channel using the alpha identifier, use the cursor knob to move the cursor
square around the alpha identifier as shown below. Turn the value knob until the channel is your
desired channel. Notice that channels change alphabetically.
J. Using the Direct/Repeat Feature
The P-2000 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 P-2000 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. The direct mode indicator will light. The
following illustration shows radio 1 in direct mode.

(1) Transmitting
To transmit on a radio system, select the appropriate source on your audio panel, and key
the microphone. Transmission will begin on the radio’s currently selected Active channel.
During the transmission, the radio’s transmit indicator will light, and the channel’s transmit
frequency will be displayed. The following illustration depicts FM #1 transmitting.
(2) Receiving
The P-2000 is constantly monitoring its radios for reception. When a signal is received, the
P-2000 will light the receive indicator for the receiving radio, and route the audio to the
operator’s headset (Assuming the associated intercom switch is selected). The following
illustration depicts FM #2 receiving.

When the user presses the QMEM key, the system will enter the QMEM mode. This mode allows
the user to either select or program a QMEM location. When the user presses the QMEM key,
then presses a keypad key (0-9), the channel programmed into the corresponding (0-9) QMEM
location shall be loaded into the active channel, and the previously active channel shall be loaded
into the standby channel. If the user presses the QMEM key, then presses and holds down a keypad
key (0-9) for 3 or more seconds, the current active channel shall be programmed into the
corresponding QMEM location. Should the user not press any key for more than 4 seconds after
pressing the QMEM key, the QMEM operation shall automatically be canceled. The user can
cancel the QMEM operation by pressing the HOME key. The figure below shows the QMEM
operation in mid stream.
(1) To store a channel into a QMEM position first put the desired channel in the
active channel and press the QMEM button. The figure below shows what
the display will look like.
(2) At this point press and hold button 0-9 until the status line indicates the storage
operation is completed, as shown in the picture below:
(3) To load the active channel using QMEM, simply push the QMEM button followed
by a 0-9 button and the programmed channel will be automatically loaded into
the active channel. If that QMEM position has not been programmed with a
channel, the status line will indicate to the user no channel is programmed.
