land, mobile and tactical line-of sight communications as well as military and civilian air traffic

control operations. Secure communications can be achieved with an appropriate external

encryption device and with the transceiver in the data [Cipher Text (CT)] mode.

NOTICE

The URC-200 (V2) is FCC certified in the 115-149.995 (AM) and

115 - 173.995 (FM) bands.

1. The URC-200 (V2) transceiver is to be tuned only to those frequencies that

the transceiver user, by law, is permitted to use.

2. Operation and tuning of the transceiver should be restricted to those users

who are knowledgeable about which frequencies are authorized for use.

3. Transceiver operation on unauthorized frequencies is a violation of the law.

4. The capabilities of this transceiver allow users the freedom for authorized

personnel to easily tune the transceiver. This allows the transceiver to work with

other communication systems within the band, provided that the transceiver's

tuned frequencies are permitted by regulation.

SECTION 2. OPERATION

2-1. GENERAL INFORMATION

This section provides information for operating the URC-200 (V2) Transceiver. It includes a

functional description of all operating controls, indicators, and connectors and procedures for set-

up and operation.

NOTE

Lithium Battery Pre-Conditioning

When using BA-5590/U lithium batteries, General Dynamics C4

Systems recommends that the user consult MIL-B-49430 (ER),

"MIL-SPEC, Batteries, non-rechargeable, Lithium Sulfur Dioxide",

and MIL-B-49430/3D (ER) "MIL-SPEC, Batteries, non-

rechargeable, Lithium Sulfur Dioxide BA-5590/U." Particular

attention should be paid to the paragraphs relating to voltage

delay of the BA-5590/U.

It is recommended that the batteries be changed in pairs.

New, unconditioned, lithium batteries may not be able to deliver

the current required to allow the transceiver to transmit in high

power. To condition the lithium batteries the user can, after

installing the new batteries, set the transceiver to low power and

key the transmitter for 20 to 30 seconds, then set the transceiver

to medium power and again key the transmitter for 20 to 30

seconds, the batteries should now be conditioned and capable of

supplying sufficient current to allow the transceiver to transmit in

the high power mode.

2-2. CONTROLS, INDICATORS AND CONNECTORS

The URC-200 (V2) uses a microprocessor to control and display all operating functions. A

key-pad with 12 key switches is used with a Liquid Crystal Display (LCD) to select frequencies

and operating modes for each of the 10 preset channels and to store each channel's operating

parameters. Separate volume and squelch controls are provided to adjust the handset and

loudspeaker audio level and the receiver squelch threshold. The controls, indicators and

connectors shown in Figure 2-1 are explained in Table 2-1. The display and key-pad functions

are shown and explained in Figure 2-2.

2-3. KEYPAD AND DISPLAY FUNCTIONS

The following procedures describe how to set-up the transceiver for operation in any of the

possible operating modes. Figure 2-2 shows the display and the key-pad and identifies the key

functions. Each will be discussed in further detail as specific operating modes are described.

2-4

Figure 2-2. Key-pad and Display Functions

2-3.1. NORMAL OPERATING MODE CONFIGURATION PROCEDURES

The transceiver can be used for operation once it has been installed as described in Section

3. The transceiver is fully micro-processor-controlled from push button instructions selected at the

front panel. The frequency is tuned either by selecting one of ten preset channels or by manually

setting up the frequency on the LCD display. The preset frequencies may be stored in memory

and may be changed any time the transceiver is turned on. The memory is maintained using an

EEPROM that allows the presets to be stored even when the power is turned off or the

transceiver batteries are removed. The EEPROM provides non-volatile memory and does not

require the use of a keep-alive-voltage.

In normal operating mode, the display will show the channel currently in use. The receive

frequency and its associated data for that channel will be displayed while the transceiver is in

receive mode. When the PTT is pressed, the transmit frequency and its associated data for that

channel will be displayed. When transmitting, the transmit annunciator (TX) will be on.

If the [R/T] key is pressed while in receive mode, the transmit frequency will be displayed,

but the transceiver will still be receiving on the current channel's receive frequency. This situation

is indicated by a blinking transmit annunciator. Pressing PTT at this point will put the transceiver

in transmit mode, causing the transmit annunciator to come on steadily. When the PTT is

released, the transceiver will go back into receive mode with the receive frequency and data for

this channel being displayed.

2-5

2-3.1.1 Turning on the Unit

Before performing the following steps, refer to Paragraph 2-2 for the location and functional

description of the controls and indicators.

1. Make sure the transceiver set is connected for operation according to the installation

instructions in Section 3.

2. Turn on the transceiver by turning the VOL control clockwise.

3. Set the VOL control for the desired volume (the SQ control must be in maximum counter

clockwise position). To hear audio from the loudspeaker the speaker must be enabled

per Paragraph 2-3.1.4.

4. Adjust the SQ control for the threshold by advancing clockwise slowly, just until the noise

stops. Advancing the control further will reduce the sensitivity of squelch break.

2-3.1.2 Cancellation of Presets

If the transceiver is powered-up while the [MODE] key is pressed, the

transceiver will preset all the channel data for each channel to the default

values (225 MHz, PT, AM, low power). It is this default condition that is used

as the starting point for the following discussions.

2-3.1.3 Front Panel Illumination

LAMP

Pressing the [LAMP] key Controls the backlighting of the display and

keyboard. Consecutive key strokes cycles through the four levels of brightness

-- off No backlighting), low, medium, and high.

When the transceiver is turned ON, the normal default from the factory is with

the backlighting off.

2-3.1.4 Select Speaker ON/OFF

SPKR

PT MODE

SPKR

Pressing the [SPKR] key toggles the loudspeaker ON and OFF. When the

[SPKR] key toggles the loudspeaker ON, the SPKR annunciator will appear in

the upper right corner of the display. This is to signify that the loudspeaker has

been turned ON. When the [SPKR] key toggles the loudspeaker OFF, the

SPKR annunciator will disappear.

When the transceiver is turned ON, the normal default from the factory is with

the speaker off.

2-6

2-3.1.5 Select Meter Mode

Pressing the [MODE] key and then the [PWR] key activates the METER

MODE. When the transceiver is in the receive mode, the display becomes a

signal strength meter in the form of a bargraph, indicating the relative strength

of the incoming receive signal. The meter will indicate a single bar at

approximately -115 dBm and be full scale at approximately +3 dBm.

When the transceiver is in the transmit mode (PTT pressed), indicated by the

TX annunciator, the display becomes a power meter. At high UHF frequencies

its accuracy is approximately 1 Watt per bar. As frequency decreases the

power meter may be indicating a decrease in output power. This does not

reflect a true reduction in output power. The true output power will be within

specification across the frequency band.

2-3.2. SETTING PRESET CHANNELS

This section describes how the preset channels are set. The transceiver is initially assumed

to be set-up with the following conditions: low power, AM, plain text (PT), and a frequency of 225

MHz (for both receive and transmit), these are default values that are achieved when the

transceiver is powered-up with the [MODE] key pressed, as described in Paragraph 2-3.1.,

above. The transceiver does not need to be set-up with these default settings; the following

procedure applies for any settings except that the display examples will be different.

2-3.2.1 Select Preset Channels

Pressing the [CH] key and then one of the numbered [n] keys, selects channel

[n], the display shows the frequency and the attributes associated with that

channel. This example shows the key-press sequence for selecting Preset

Channel 1. Any channel from 0 to 9 may be selected.

2-7

2-3.2.2 Select Frequencies

With a channel set-up as above, pressing the [FREQ] key (key-pad [1]) the

transceiver will go into the "enter frequency" mode. The main display is

blanked out except for the channel number (the number shown to the left the

colon). The first digit of the desired frequency (1, 2, or 3) is pressed next and is

displayed to the right of the colon. At this point, the transceiver will still be

receiving on the same frequency as before. As the remaining digits of the

desired frequency are entered, they will be displayed. Pressing the [<--] key

will cause the last digit entered to be erased. If the first digit of the frequency is

erased, the display will go back to showing the current receive frequency for

this channel. When the sixth digit of the frequency is entered, the rest of the

frequency is automatically determined, so the correct frequency is displayed

and the transceiver is set to that frequency. Note that this can be used as a

"manual" receive channel since the new frequency and any other associated

data that has been changed will not be stored in memory until the [STO] key is

pressed. If the Receive mode display is shown, entering the frequency will

change the frequency for both Receive and Transmit frequencies. If the

Transmit mode display is shown, entering the frequency changes only the

Transmit frequency. If a flashing frequency is displayed on the transceiver’s

screen, it may be an indication that an invalid frequency was entered into the

transceiver. Reenter the frequency with a valid frequency.

NOTE

It is possible to enter a frequency in the 30 to 90MHz frequency band

either through the transceiver’s front panel keypad or through the RS-232

ports on the J2 Remote Connector even though the 30 to 90MHz

Enhancement Option is not installed in the transceiver. If a frequency in

this range is entered and the 30 to 90MHz Enhancement Option is not

installed, the frequency displayed on the transceiver’s front panel will flash.

Also, the transceiver’s receiver and transmitter will not respond to the

invalid frequency.

By reentering the frequency with a valid frequency from the keypad or

through the RS-232 ports the flashing display will cease and the

transceiver will return to normal operation.

2-3.2.3 Select Modulation Mode

AM/FM

AM FM

Pressing the [AM/FM] key causes the transceiver to toggle between the AM

and FM modulation modes for the currently-displayed channel. The new value

will take effect immediately, as indicated by the annunciator, but will not be

stored until the [STO] key is pressed. This select automatically applies to both

sides of the preset channel, i.e., if AM is selected for the receive frequency,

the transmit frequency is also AM. If the new modulation is AM and the

transmit power level was MED, the power level will be automatically changed

to HI (there is no AM MED level). If the Receive mode display is shown, the

new modulation will apply to both the Receive and Transmit frequencies. If the

Transmit mode display is shown, the new modulation will apply to the transmit

frequency only.

2-8

2-3.2.4 Select Cipher Text/Plain Text

Pressing the [PCV] key toggles between the plain-text and cipher-text (data)

modes for the currently-displayed channel. The new value will take effect

immediately when the [STO] key is pressed, as indicated by the annunciator.

2-3.2.5 Select Receive/Transmit Data

R/T

Pressing the [R/T] key switches the display between the receive frequency and

its operating data for the selected channel and the transmit frequency and data

for that channel. When the transmit data is displayed, the transmit

annunciator, TX will blink. This key is also used as "back-space" when in the

frequency select mode as described in Paragraph 2-3.2.2.

2-3.2.6 Storing Presets

STO

Pressing the [STO] key stores into memory the frequencies (receive and

transmit), mode (PT/CT), modulation (AM/FM), transmit power (Tx),

bandwidth, and scan list membership for the selected channel.

2-3.2.7 Select Scan Channels

Pressing the [SCAN] key switches the selected preset channel on or off the

scan list. The scan list must contain from two to ten of the preset channels

before the scan mode can operate. The SCAN annunciator will light to indicate

that this preset channel is on the scan list.

2-9

2-3.2.8 Select Transmit Power Levels

LO MED HI

PWR

Pressing the [PWR] key selects the transmit power levels for the transceiver.

The power level annunciator will show the current setting. There are three

power levels, LO, MED, and HI, available in the FM modulation mode and two

power levels, LO and HI, when AM is selected.

2-3.3. SELECTING SPECIAL MODES

The following paragraphs describe the procedures for special operating modes and

functions of the transceiver. The special operating modes consist of the Beacon-, Guard-, and

Scan-mode of operation. The special functions consist of Self Calibration of Receive Filters,

Internal Voltage Measurements, and Return to Local Control from Remote operation.

2-3.3.1 Select Scan Mode

Pressing the [MODE] key and then the [SCAN] key activates or de-activates

the SCAN MODE. The scan mode causes the transceiver to cycle through the

preset channels which are flagged as "scan channels", (see Paragraph 2-

3.2.7), searching for an active channel I.e., one where incoming signal

strength is sufficiently large to break squelch). While scanning, the display will

show the channel that it is scanning. The transceiver will scan for 0.5 second

on each selected scan channel. If an active channel is found, the transceiver

will lock on that channel. If that channel becomes inactive for approximately

four seconds, the transceiver will continue the scan with the next flagged

channel. If the operator wishes to continue the scan while on a channel that is

(or was) active, the [SCAN] key can be pressed. When an active channel is

found, that channel's receive frequency will be displayed. If the push-to-talk

key (PTT) is pressed while the transceiver is scanning, it will be ignored. If the

PTT is pressed while a channel is active, the transceiver will go out of scan

mode and into the normal mode using that channel, transmitting on that

channel's preset transmit frequency. If the scan list has less than two

channels, then the LCD will blink "Err-noSC" indicating the transceiver cannot

enter the scan mode. To return to normal operation press the [CH] key

followed by one of the 10 channel numbers [0 through 9]. The Scan Mode will

be cancelled and the transceiver will go to the selected channel.

When the scan mode is de-activated normally, by using the [MODE] plus

[SCAN] keys, or by turning the transceiver OFF then ON, the transceiver will

return to normal operation on the channel which was in use immediately prior

to entering the SCAN MODE.

2-10

2-3.3.2 Select Beacon Mode

Pressing the [MODE] key and then the [BCN] key activates or de-activates the

BEACON MODE. When the BEACON MODE is selected, the transceiver

transmits a sweeping emergency audio signal on the selected channel

frequency and in the selected modulation mode (AM or FM). The display

alternately switches between the word "BEACON" and the selected channel

information. No other operating functions are available when the BEACON is

active.

When the beacon mode is de-activated (by toggling the mode off or by

turning the power OFF and then ON), the transceiver will go back into normal

mode using the channel that was in use immediately prior to entering the

BEACON MODE.

2-3.3.3 Internal Voltage Measurements

With the transceiver set-up in the meter-mode per Paragraph 2-3.1.5.,

pressing the [R/T] key will display the voltages of the internal power supplies

and of the batteries. The first time [R/T] is pressed the voltage of the +5Vdc

supply - PS1 is displayed. Each consecutive press of [R/T] brings up the next

supply; PS2: +12Vdc, PS3: -5Vdc, PS4: -12Vdc, PS5: +24Vdc (external power

batteries), PS6: +70Vdc and AGC. NOTE

The voltages displayed on the front panel are relative voltages. If a

voltage/s appears to be too low or too high, measure the suspected

voltage using a lab type voltmeter. The AGC level displayed is not a

voltage. The AGC level is expressed as a digital value from 000 to 255.

2-3.3.4 Release from Remote Control

Pressing the [MODE] key and then the [R/T] key returns the transceiver to

local control from remote control. This sequence is called Release Remote

Key Sequence (RRKS). This key sequence has no effect if the transceiver is

not in the remote control mode. There is no on-screen indication that the

transceiver is back in local mode.

2-4. ECS-8 8.33 KHZ OPTION

This is the 8.33 kHz tuning increment / channel spacing option. The features of this option are

only available if this option has been installed. If your transceiver has this option installed, refer to

Section 5 for detailed information and operating procedures.

2-11

2-5. OPERATING PROCEDURE

2.5.1 SITING

The transceiver operates in the VHF and UHF frequency bands, these are Line-Of Sight

(LOS) frequencies; therefore, siting of the transceiver greatly affects its operating range. The

longest range is normally obtained when a direct LOS is maintained between the transceivers.

Use of hilltop or tower locations will increase the LOS range. Location in valleys with intervening

hills, behind buildings or in dense woods may reduce or prevent communications. If possible,

avoid locations near electrical interference sources, such as power and telephone lines, radars,

welders and electrical generators.

2-5.1. UNENCRYPTED OPERATION

The following procedure allows unencrypted operation.

1. Attach the VHF/UHF antenna and H-189/GR handset to the transceiver.

2. Turn the transceiver on by rotating the VOL control clockwise.

3. Set the transceiver PT.

4. Set the SQ control to OFF and set the VOL control until noise is heard from the

handset or the loudspeaker If enabled per Paragraph 2-3.1.4).

5. Select operating modes and frequencies per Paragraph 2-3.

6. To transmit, hold the H-189/GR handset Push-To-Talk (PTT) switch down while

talking into the mouthpiece.

7. To receive, release the PTT switch and listen to the handset earpiece or to the

loudspeaker.

8. To eliminate the background noise when no receive signal is present, turn the SQ

control clockwise just until the noise turns off. Adjusting the control further clockwise

reduces the sensitivity of the squelch-break.

2-6. URC-200 (V2) EEPROM LIMITATIONS

The URC-200 (V2) transceivers use the Freescale MC9S08DN60AMLH microprocessor for

control and interface operations of the transceiver. The processor has 2048 bytes of internal

EEPROM that is capable of storing data after the power has been turned off. The EEPROM's

write cycle (an erase followed by a write) is only guaranteed for 100,000 operations. However,

typical operational life at ambient temperatures (approximately +25C) is much greater.

Excessive use of the following commands will result in a reduction in the EEPROM's write

and dispose of it by following approved procedures.

3-2

NOTE

Lithium Battery Pre-Conditioning

When using BA-5590/U lithium batteries, General Dynamics – C4

Systems recommends that the user consult MIL-B-49430 (ER),

'MIL-SPEC, Batteries, non-rechargeable, Lithium Sulfur Dioxide',

and MIL-B-49430/3D (ER) 'MIL-SPEC, Batteries, non-

rechargeable, Lithium Sulfur Dioxide BA-5590/U.' Particular

attention should be paid to the paragraphs relating to voltage

delay of the BA-5590/U.

It is recommended that the batteries be changed in pairs.

New, unconditioned, lithium batteries may not be able to deliver

the current required to allow the transceiver to transmit in high

power. To condition the lithium batteries the user can, after

installing the new batteries, set the transceiver to low power and

key the transmitter for 20 to 30 seconds, then set the transceiver

to medium power and again key the transmitter for 20 to 30

seconds, the batteries should now be conditioned and capable of

supplying sufficient current to allow the transceiver to transmit in

the high power mode.

The battery case holds two batteries. Always use two of the same type battery when

replacing batteries. To replace the batteries, follow these instructions:

1. Turn off the transceiver by turning VOL/OFF control to OFF.

2. Set transceiver face down on the front panel handles.

3. Undo the two latches, located on the side of the transceiver to unlatch the

battery case from the transceiver.

4. Pull the battery case straight up and away from the transceiver.

5. Remove the used batteries from the transceiver by pulling straight up.

6. Plug new batteries into the transceiver.

7. Slide battery case over the batteries and into the rear skirt of the transceiver,

fastening it into place with the two latches.

3-2.3. ATTACHING AND REMOVING THE HANDSET

Attach the handset to the HDST connector. The O-ring seal on the handset may require

considerable exertion before rotating the mating connector clockwise into a locked position.

3-2.4. ATTACHING THE ANTENNA

3-2.4.1 Attaching the Antenna

Before attaching the UVU-100 LOS antenna to the transceiver, verify the ball and swivel joint

at the mounting base of the antenna is free to swivel. If it is not free, then loosen the swivel clamp

ring from the collar ring. These two rings are located at the antenna base. With the ball and

swivel joint free to swivel, screw the antenna to the ANT connector with only the collar ring.

Exercise Extreme Care to prevent the threads on the collar ring from cross-threading with the

threads on the ANT connector. To set the antenna in a vertical position, tighten the swivel joint

clamp ring against the collar ring with the antenna in its proper position. With the swivel joint

clamp ring tightened, DO NOT use the antenna as a lever to cinch the collar ring to the ANT

connector.

3-3

CAUTION

Several conditions must be observed when using the UVU-100

LOS antenna mounted on the transceiver's front panel, as serious

damage to the transceiver may result if high RF power is allowed

to leak into the interior of the transceiver directly from the antenna.

1. Transmit ONLY with the cover of the transceiver securely

fastened in place.

2. Use ONLY vendor supplied power supplies, such as the RF

shielded battery case (UBC-100) or power supply (UAC-100).

3. Use ONLY TEMPEST approved shielded cables to the X-

MODE connector.

3. Use ONLY TEMPEST approved shielded cables to the X-

MODE connector.

CAUTION

To comply with RF exposure requirements, a

minimum separation distance of 20 cm (7.9 inches)

is required between the antenna and all persons

while the transceiver is transmitting.

3-2.4.2 Removing the Antenna

To remove the antenna from the transceiver, first loosen the swivel clamp ring to allow the

ball and swivel joint, at the antenna’s mounting base, to freely swivel. Then unscrew the collar

ring from the ANT connector and remove the antenna. With the swivel joint clamp ring tightened,

DO NOT use the antenna as a lever to loosen or remove the collar ring from the ANT connector.

3-3. REMOTE OPERATION

The Remote Control Unit (RCU) shown in Figure 3-1 can either be a personal computer or it can

be a Remote Terminal Unit (a handset, or a control head connected by a cable of up to 250 ft).

As shown, the RCU is connected in a master/slave relationship to the transceiver and the RCU

always initiates a given command. All commands are sent as a series of ASCII characters over

the RS232 connection.

RCU RADIO

(MASTER) (SLAVE)

Figure 3-1. Remote-Control Unit

When first powered up, the RCU sends an ID interrogation code to query what type of radio it is

connected to (what options have been attached). Given this information, the RCU restricts the

type of commands that it can transmit to the transceiver. When the remote command is

recognized by the transceiver as a valid command, the transceiver will enter into the slave mode

(the RCU is the master with the transceiver as the slave). The transceiver will also lock out all

local keyboard inputs (except for the Release Remote Key Sequence, RRKS: [Mode] [R/T])

allowing all commands to come from the RCU.

3-3.1. REMOTE CONTROL INTERCONNECT

3-3.1.3 Data Exchange Protocol

The RCU initiates all configuration commands and status inquiries to the transceiver using the

RS-232 data communication protocol. Configuration commands control a change of state or a

parameter of the transceiver such as AM/FM or transmit frequency. Status inquiries return

transceiver data such as internal power supply voltage levels.

Each command or inquiry results in a response from the transceiver. If the transceiver receives a

valid command, it performs the command and responds with an ACK reply to the RCU. If the

transceiver receives an inquiry that requires a data response, the data is sent first, followed by

ACK. If the transceiver receives an invalid command, it responds with a NAK reply. In the case

where the transceiver is in manual (keypad) mode and it is commanded to change to the remote

mode, it first responds with HT and then responds to further commands with ACK or NAK.

The ACK, NAK, and HT remote responses are summarized in Table 3-1.

3-6

Table 3-1. Remote Responses

CODE NAME DESCRIPTION

ACK Acknowledge Response from the transceiver to a valid RCU command. If the

command requires data from the transceiver, the data is sent first,

followed by ACK.

NAK No Acknowledge Response from the transceiver to an invalid RCU command.

HT New

acknowledge

A response from the transceiver indicating that the transceiver was in

the keypad (manual) command mode at the time it received a remote

command. The transceiver changes mode to the remote command

mode and sends HT. This acknowledge is used instead of an ACK for

the first valid remote command received when transceiver was in

keypad command mode.

The RCU cannot send a new command until it receives an ACK/NAK/HT or times out,

whichever occurs first. If the RCU receives a NAK or times out, send the Z command to re-

establish sync with the transceiver.

Provisions must be made on the RCU side to poll the status of the transceiver especially in

the over-temp, scan, and synth lock conditions. Another provision that the RCU should make is

that after three (3) NAKs from the transceiver for the same command, the RCU should display an

error code to indicate that an interface problem or an invalid command has occurred.

The RCU (handset or control head) should display the status on its LCD display only after it

has queried the transceiver for data. In this way, the RTU and the transceiver displays will always

agree.

NOTE

To conserve power, the RS232 transmitter in the transceiver is

automatically turned off after an ACK or HT is sent. This

essentially puts the TX in the break state. The remote software

must handle any special interrupts etc. that may occur as a result

of a break.

3-3.2. REMOTE CONTROL CODES

The following tables show the remote control command codes for the URC-200 (V2)

Transceiver. The commands are organized as follows:

 Remote Transceiver Operation Commands

 Transceiver Customizing Commands

 Transceiver Status Inquiry Commands

The codes for the basic transceiver as well as those for the available options are included in

the tables. The available options are:

 30 - 90 MHz extended frequency option, EBN-30

 400 - 420 MHz extended frequency option, EBN-400

 8.33 kHz tuning increment / channel spacing option, ECS-8

Many of the commands are only valid for certain transceiver configurations and frequency

ranges, Table 3-2 provides a mapping of these dependencies. In Table 3-3, the commands

affected by these dependencies are indicated by a reference to “Note 1” below the command. For

example, if the transceiver is equipped with the 30-90 MHz option, AM is not available, but FM,

PT and CT are, including the other parameters in the remainder of the column. Similarly, 8.33

kHz tuning is available only for the 115 - 173.995 MHz and 225 - 399.995 MHz bands.

WARNING

DO NOT THROW BATTERIES IN THE TRASH

Dispose of all used batteries in accordance with all Federal, State

and local laws and regulations. Lithium batteries may be used in

the URC-200 (V2) Transceiver however lithium batteries contain

hazardous materials.

Improper handling, reverse-current operation or high

environmental temperatures may cause internally generated heat,

fire or toxic materials and gasses to be released from the battery.

The following precautions must be strictly observed to prevent

injury to personnel or damage to equipment:

 DO NOT heat, incinerate, crush, puncture, disassemble or

mutilate the batteries.

 DO NOT recharge primary Non- rechargeable) batteries.

 DO NOT store in equipment during periods of non-use for

more than 30 days.

 DO follow all safety instructions that come with the batteries or

printed on them.

 TURN OFF the equipment immediately if you (1) detect that

the battery compartment is becoming unduly hot, (2) hear battery

cells venting (hissing), or (3) smell irritating sulfur dioxide gas.

Remove the battery only after it is cool (after 30 to 60 minutes),

and dispose of it by following approved procedures.

The following tests evaluate the performance of the receiver circuits. The functions that will

be tested are receiver sensitivity and distortion at various frequencies in AM and FM, and in CT

and PT modes. Squelch sensitivity will also be checked. If the transceiver fails any of the tests, or

if it cannot be adjusted to specified values, it must be sent to General Dynamics C4 Systems for

repair.

WARNING

DO NOT THROW BATTERIES IN THE TRASH

Dispose of all used batteries in accordance with all Federal, State

and local laws and regulations. Lithium batteries may be used in

the URC-200 (V2) Transceiver however lithium batteries contain

hazardous materials.

Improper handling, reverse-current operation or high

environmental temperatures may cause internally generated heat,

fire or toxic materials and gasses to be released from the battery.

The following precautions must be strictly observed to prevent

injury to personnel or damage to equipment:

 DO NOT heat, incinerate, crush, puncture, disassemble or

mutilate the batteries.

 DO NOT recharge primary Non- rechargeable) batteries.

 DO NOT store in equipment during periods of non-use for

more than 30 days.

 DO follow all safety instructions that come with the batteries or

printed on them.

 TURN OFF the equipment immediately if you (1) detect that

the battery compartment is becoming unduly hot, (2) hear battery

cells venting (hissing), or (3) smell irritating sulfur dioxide gas.

Remove the battery only after it is cool (after 30 to 60 minutes),

and dispose of it by following approved procedures.

compatible with other radios in this band of frequencies. If desired, the tone may be turned OFF,

however, “white-noise” will be coming from the speaker.

5-1.3. LIMITATIONS

5-1.3.1 Modulation:

The URC-200 (V2) using the 30 to 90 MHz option will receive and transmit FM modulation

only.

5-1.3.2 Carrier-to-Noise Squelch:

The carrier-to-noise squelch, which is set by the Squelch Control when the URC-200 (V2) is

in the VHF or UHF frequency bands, is effectively disabled in 30-90 MHz band.

5-1.3.3 Select Meter Mode:

The front panel display signal strength meter and power meter do not operate when the

transceiver is in the 30 to 90 MHz band.

5-1.3.4 UEC-120/220 Remote Control Optional Accessory:

Use only the UEC-120/220 Remote Control Units when operating the URC-200 (V2) with the

30 to 90 MHz Option. The optional remote control accessory, UEC-100/200, was designed only

for the VHF and UHF frequency bands. The UEC-100/200 will not operate in the 30 to 90 MHz

(LVHF) frequency band and, therefore, cannot be used with the URC-200 (V2) when using the

LVHF band.

5-1.4. SPECIFICATIONS

5-1.6. INSTALLATION AND OPERATION

5-1.6.1 Siting:

Although ionospheric scatter propagation is possible in the 30 to 90 MHz range, the results

can be unpredictable and sporadic. When using the URC-200 (V2) in the 30 to 90 MHz

5-3

frequency band (LVHF) it is recommended that the same line-of-sight (LOS) siting considerations

be applied as when operating in the VHF or UHF frequency bands.

5-1.6.2 Antenna Installation:

Connect the LVHF antenna to the type “N” connector on the front panel. Route the

gooseneck portion of the antenna base so the antenna is oriented vertically. Satisfactory

performance is achieved with the LVHF antenna and the VHF/UHF antenna mounted on the

URC-200 (V2) at the same time. However, the unused antenna should be removed for optimum

antenna performance.

5-1.6.3 Selecting LVHF Frequencies:

Press the [FREQ] key (keypad [1]) to select the frequency entry mode. To select a frequency

in the LVHF band, a zero (0) must be pressed before entering the desired frequency. For

example, to enter 35.6 MHz, press [0] [3] [5] [6] [0] [0].

5-1.6.4 Squelch:

The 30 to 90 MHz band employs a 150 Hz Tone Squelch. To activate the Tone Squelch,

press the [TONE] key (keypad [2]). A lower case “t” will appear at the 100 MHz position on the

display when the Tone Squelch is active, or turned ON. When using the 150 Hz Tone Squelch,

the Squelch Control will not effect the tone squelch threshold. It should be noted that the only

signals that will break the receiver’s squelch, when the Tone Squelch is ON, are those that are

on-channel and are being modulated with a 150 Hz tone that has a sufficient deviation level to

break the receiver’s tone squelch threshold.

If desired, the 150 Hz Tone Squelch may be deactivated, or turned OFF. The lower case “t”

will disappear from the 100 MHz position on the display when the Tone Squelch is turned OFF.

With the tone turned OFF there is no squelching of the white-noise on the URC-200 (V2).

Press the [FREQ] key (keypad [1]) to select frequency entry mode. To select a frequency,

enter the desired frequency.

5-3. ECS- 8 OPTION - PART NUMBER 01-P42311K001

5-3.1. GENERAL INFORMATION

This option allows 8.33 kHz tuning in the VHF/UHF bands, and user selectable 8.33 kHz

receive channel spacing in the 117.9750 to 136.9750 MHz band.

It also allows the operator to place the radio into Aviation mode, which restricts the operating

frequency range from 117.9750 to 136.9750 kHz, with tuning increments of 25 and 8.33 kHz.

Channel spacings of 25 or 8.33 kHz are assigned automatically by frequency, following the ICAO

standards for frequency entry.

This mode also restricts modulation to AM, and allows PT only, disabling the CT feature of

the radio.

5-3.2. ENABLING AVIATION MODE

To place the transceiver in the Aviation Mode, start with the

transceiver powered off and then press and hold the 4 [AV]

keypad while turning on the power. The unit will remain in

the aviation mode through subsequent power cycles until it

is returned to the normal operating mode.

The transceiver will set all the channel data for each

channel to a default value (118 MHz, PT, AM, 25 kHz

bandwidth, low power).

To return to the normal operating mode, start with the

transceiver powered off and press and hold the 6 [MODE]

key while turning on power.

The transceiver will reset all the channel data for each

channel to the default values (225 MHz, PT, AM, 25 kHz

bandwidth, low power).

5-3.3. TUNING AND CHANNEL SPACING IN AVIATION MODE

When in the Aviation Mode, the manner in which the frequency is entered and displayed

determines the actual operating frequency and the channel spacing. The ICAO standard

mandates that specific channel spacings (either 25 or 8.33 kHz) shall be assigned to specific

frequency entries. This also means the frequency that is entered and displayed may be different

from the actual frequency the transceiver is tuned to.

The Aviation Mode Frequency Chart below shows an example of how to enter frequencies

to select the desired operating frequency and channel spacing. 118 MHz is used in the table as

an example; however any frequency from 117.9750 to 136.9750 kHz may be selected.

For example, if the desired actual operating frequency is 118.000 MHz with a channel

spacing of 25 kHz, enter 118000 using the keypad or remote command. The result will be what is

shown in line 1 of the chart. If, however, the desired frequency is still 118.000 MHz but this time

with a channel spacing of 8.33kHz, enter 118005 and the result will be as shown in line 2 of the

chart. Note that the transceiver will display 118005 even though it is tuned to 118.000 MHz.

In some cases, only 8.33 kHz channel spacing is allowed. Examine lines 3 and 4 of the

chart. Because tuning increments of 8.33 kHz are allowed, the next possible operating frequency

after 118.000 MHz is 118.0083 MHz. In this case only 8.33 kHz channel spacing is available for

5-6

this frequency. To tune this frequency, enter 118010 into the transceiver. The entered value is

what will be displayed even though the transceiver will be operating at 118.0083 MHz.

In a similar fashion, line 4 of the chart shows that the next available frequency is 118.0166

MHz. This also is only allowed to have a channel spacing of 8.33 kHz. But to operate at this

setting, enter 118015 to the transceiver.

Lines 5 and 6 of the chart show that the process repeats at this point.

If the user attempts to enter a frequency that is not allowed, the transceiver will simply not

accept the input until a valid value is entered.

5-3.4. TUNING INCREMENT VS. CHANNEL SPACING, ELECTRICAL CHARACTERISTICS

The terms “tuning increment” and “channel spacing” are often misinterpreted. By definition:

 The “tuning increment” is the minimum incremental change in operating frequency of which a

transceiver is capable.

 The “channel spacing” is the window (or the bandwidth in kHz) that a tuned transceiver will

operate in and represents the minimum acceptable adjacent channel separation. This

window or bandwidth is determined by the receiver’s IF selectivity (bandwidth). In the URC-

200 (V2), whether the tuning increment is 5kHz, 12.5kHz, 8.33kHz, or 25kHz the IF selectivity

does not change. (The IF selectivity specifications for the URC-200 (V2) is outlined in

Table 1-1 of this manual.

NOTE

Exercise care when communicating between various transceivers. If a 5kHz,

8.33kHz, or 12.5kHz tuning increment is used, the URC-200 (V2) Transceiver could

receive an adjacent channel’s signal. Depending what the channel spacing

specification is of the adjacent channel transceiver, the URC-200 (V2) Transceiver

may not be able to communicate back to it unless it is re-tuned to the on-channel

frequency of the adjacent channel transceiver.
