Ge n e ra l Dyn a m ic s C4 S ys te m s URC-200 (V2) 3.3 Transmitter Functional Description Figure 8 shows the functional block diagram for the transmitter. In the transmit mode, the synthesizer generates the transmit signal at the operating frequency in response to frequency data supplied by the processor.
Page 38: Mhz Option Functional Description
Ge n e ra l Dyn a m ic s C4 S ys te m s URC-200 (V2) The transmitter may be modulated with either AM or FM modulation using either Plain Text (audio) or Cipher Text (data) signals. Both the Plain Text and Cipher Text signals are processed through the same filtering and amplification circuitry used to process the baseband signals in the receive mode.

Ge n e ra l Dyn a m ic s C4 S ys te m s URC-200 (V2) 4.4 Normal Operating Mode Configuration Procedures The transceiver can be used for operation once it has been installed. The transceiver is fully micro- processor-controlled from push button instructions selected at the front panel.
Page 47: Cancellation Of Presets
Ge n e ra l Dyn a m ic s C4 S ys te m s URC-200 (V2) 4.4.2 Cancellation of Presets To cancel presets, press the [Mode] key while powering on the radio. 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, 25 kHz channel spacing).
Page 48: Setting Preset Channels
Ge n e ra l Dyn a m ic s C4 S ys te m s URC-200 (V2) 4.4.6 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 4.4.2, above.
Page 49 The transceiver will not accept invalid frequencies. If a flashing frequency is displayed on the transceiver’s screen, it may be an indication that a malfunction has occurred. Contact General Dynamics Customer Support for further information if this occurs. 4.4.6.3 Select Modulation Mode Pressing the [AM/FM] key causes the transceiver to toggle between the AM and FM modulation modes for the currently displayed channel.
Page 50 Ge n e ra l Dyn a m ic s C4 S ys te m s URC-200 (V2) 4.4.6.4 Select Cipher Text/Plain Text Press the [PT/CT] key to toggle between the plain text and cipher text (data) modes for the currently displayed channel. The new value will take effect immediately, as indicated by the annunciator, but will not be saved until the [STO] key is pressed.
Page 51: Selecting Special Modes
Ge n e ra l Dyn a m ic s C4 S ys te m s URC-200 (V2) 4.4.6.7 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.
Page 52 Ge n e ra l Dyn a m ic s C4 S ys te m s URC-200 (V2) 4.4.7.1 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 4.4.6.7), searching for an active channel (i.e., one where incoming signal strength is sufficiently large to break squelch).
Page 53 Ge n e ra l Dyn a m ic s C4 S ys te m s URC-200 (V2) 4.4.7.2 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).
Page 54: Voice (Pt) Operation
Ge n e ra l Dyn a m ic s C4 S ys te m s URC-200 (V2) 4.4.7.4 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).
Page 55: Select Scan Channels
This value should rarely require adjustment (typically once a year or less often). For information concerning the warp alignment command, please contact General Dynamics Customer Service. 4.6 Remote Operation The URC-200 (V2) can be operated remotely using one of the available Remote Control Units (UEC-120 or UEC-220) or by using a personal computer.
Page 56: Remote Control Interconnect
Ge n e ra l Dyn a m ic s C4 S ys te m s URC-200 (V2) 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.

Page 151: Appendixa - Urc-200 (V2) Crystal Warp Adjustment
RYSTAL DJUSTMENT Software version 1.6 or later only. For software versions prior to 1.6 please contact General Dynamics Customer Support. Introduction The warp adjustment is used to fine tune the transceiver’s frequency accuracy to within ±1ppm. This equates to ± 400 Hz at 400 MHz. To perform the procedure, the radio must be given the Warp command via the REMOTE connector on the front panel of the radio.
Page 152 In this example V0106 indicates the current software version – 1.6. See also Table 13 for additional information about queries. If your radio has an older version of software installed contact General Dynamics support for information concerning the Warp command.
Page 153 11. When the transmit frequency is within specifications, cycle power to the transceiver to return the radio to the normal operating mode. 12. Key the transceiver and measure the frequency. If it is within specifications, the procedure is complete. If not, contact General Dynamics technical support.
