1-1 SECTION 1. INTRODUCTION 1-1 GENERAL INFORMATION This manual provides operation and maintenance instructions for the URC-200 (V2) Radio Set shown in Figure 1-1. The radio set is a lightweight VHF/UHF transceiver providing AM/FM transmission and reception of non-secure voice or data in the frequency bands used in maritime, 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) and115 - 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. Figure 1-1.

2-1 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.

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 LAMPLAMP9 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 SPKR3 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/FMAM/FM4 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/TTX 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 AM PT LO 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 FM LO MED HI PWR8 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 cycle. 2-6.1. FRONT PANEL USER COMMAND LIMITATIONS The following front panel user commands should be used only as needed. 2-6.1.1 Select Scan Channels When a preset channel is selected or deselected for the scan list, the preset channel data is updated. Repeated use of this command may result in defective channel data. (Reference: Paragraph 2-3.2.7 and Table 3-3, "C" code. 2-6.1.2 Cancellation of Presets This command is used to initialize all channels to a default configuration (AM, low power, 225 MHz receive and transmit, PT, wideband, and off scan list). (Reference: Paragraph 2-3.1.2 and Table 3-3, "I" code. 2-6.1.3 Select Preset Channels This command changes the currently selected preset and updates the current preset channel number in the EEPROM. Excessive use of this command may result in the transceiver
2-12 always starting in preset channel 0 at power up. (Reference: Paragraph 2-3.2.1 and Table 3-3, "P" code. 2-6.1.4 Storing Presets This command allows the user to change the stored information for the current preset channel. (Receive/transmit frequency, and selection of AM or FM. Excessive use of the Q command may result in defective channel data and/or the transceiver may always start in preset channel 0 at power up. (Reference: Paragraph 2-3.2.6 and Table 3-3, "Q" code. 2-6.2. ALIGNMENT COMMAND LIMITATIONS The following alignment commands should be used only as needed. 2-6.2.1 Warp Alignment Command This is a factory setting used to set the crystal warp. This value should rarely require adjustment (typically once a year or less often). Excessive use of the warp command may result in defective crystal operation and/or loss of lock at some or all frequencies and/or the transceiver will behave as if factory initialization has not been completed. (Reference: Table 3-3, "W" code. 2-7. ERROR MESSAGES The following eight error messages are produced by the URC-200 (V2) Transceiver and are displayed on the front panel screen. The displayed error, the error title, and a description of the error are indicated below in Table 2-2. Table 2-2. Error Messages Display Error Title Description Err – bEAC Beacon Lock Failure This message indicates that there is no synthesizer lock on beacon. Err – EEPr EEprom Failure This message indicates that data could not be written into the EEPROM and that the processor should be replaced.

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.
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.
3-4 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 3-3.1.1 X-mode Connector The X-mode pins used for remote-control of the transceiver are: Pin # Description S Remote Data Out (ASCII data from the transceiver) a Remote Data In (ASCII data to the transceiver) A Ground 3-3.1.2 Data Rates and Logic Levels If using HyperTerminal, configure as shown.
3-5 The data rate is 1200 bps 5%. The data code is serial 8-bit ASCII including no parity, one start bit and one stop bit, no flow control. The logic levels for the three-wire serial interface are as follows. Pin # Description IMPEDANCE LOGIC LEVEL S Remote Data Out 470  RS232 a Remote Data In 6.8 k RS232 A Ground 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.

RECEIVER TESTS 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. 4-2.2.1 FM PT Sensitivity and Distortion 1.

4-19 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. Do not attempt to change the operating frequency while the transmitter is keyed on. Although the radio set will not be damaged, the radiated frequency will be uncontrolled during retuning and can cause unnecessary interference to other radio systems.

5-1 SECTION 5. OPTIONS 5-1. 30 TO 90 MHZ OPTION 01-P37200N001 TO THE URC-200 (V2) TRANSCEIVER 5-1.1. GENERAL INFORMATION This option provides the 30 to 90 MHz (LVHF) band to the URC-200 (V2) Radio Set. Many of the operational features in the 30 to 90 MHz frequency band are the same as in the VHF or UHF frequency bands. 5-1.2. FEATURES 5-1.2.1 Frequency Range: The 30 to 90 MHz range of frequencies resides in the Low VHF (LVHF) band of frequencies. The LVHF frequencies on the URC-200 (V2) has a center frequency tuning increment of 12.5 kHz. 5-1.2.2 Tone Squelch: Normally the URC-200 (V2) in the LVHF band will use a 150 Hz Tone Squelch which is 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 The following specifications pertain only to the 30 to 90 MHz option within a URC-200 (V2) transceiver.
5-2 General Frequency Range: LVHF - 30 to 90 MHz Modulation: FM only Receiver Characteristics Sensitivity: PT - 10 dB SINAD:  -110 dBm, 1 kHz modulation with 10 kHz deviation CT - BER (Bit Error Rate):  -105 dBm, 16 kb/sec (kilo bits per second) with 6.5 kHz deviation Spurious Response: > 80 dB Squelch Type:  150 Hz Tone Squelch (tone ON)  No squelch when the 150 Hz tone is OFF Squelch Range:  Tone Squelch: <-110 dBm, fixed trip point  No squelch when the 150 Hz tone is OFF. Transmitter Characteristics High Power Output: 5 watts +2/-1 dB (37 dBm +2/-1 dB) Medium Power Output: 1 watts +3/-2 dB (30 dBm +3/-2 dB) Low Power Output: 150 mW +3/-2 dB (21.8 dBm +3/-2 dB) Modulation: PT: 10.0 kHz at 1 kHz CT: 6.5 kHz at 8 kHz 5-1.5. REQUIRED SYSTEM EQUIPMENT The following equipment is the minimum required for a self contained LOS communications device that will operate in the LVHF band. Quantity Required Part Number Nomenclature 1 01-P36744M003 URC-200 (V2) Transceiver 1 01-P37200N001 30 to 90 MHz URC-200 (V2) Module Assembly.

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).

5-5 5-2.6. INSTALLATION AND OPERATION 5-2.6.1 Selecting 400 to 420 MHz Frequencies: 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. Aviation Mode Frequency Chart Line Number Frequency Entered (MHz) Actual Operating Frequency (MHz) Channel bandwidth (KHz) 1 118.000 118.0000 25 2 118.005 118.0000 8.33 3 118.010 118.0083 8.33 4 118.015 118.0166 8.33 5 118.025 118.0250 25 6 118.030 118.0250 8.33 7 118.035 118.0333 8.33 8 118.040 118.0416 8.33 9 118.050 118.0500 25 10 118.055 118.0500 8.33 11 118.060 118.0583 8.33 12 118.065 118.0666 8.33 13 118.075 118.0750 25 14 118.080 118.0750 8.33 15 118.085 118.0833 8.33 16 118.090 118.0916 8.33 17 118.100 118.1000 25 18 118.105 118.1000 8.33 19 etc. etc. etc. 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.
