    8/7/2003 UNPACKING & INSPECTING This equipment was factory tested, inspected, packed, and delivered to the carrier with utmost care. Do not accept shipment from carrier which shows damage or shortage until the carrier's agent endorses a statement of the irregularity on the face of the carrier's receipt. Without documentary evidence, a claim cannot be filed.

  • Page 14: Installation

    Stationary Remote Broadcast Installation The basic stationary remote installation consists of the SRPT-30/40A transmitter, a 110-120 or 220-240 VAC power source, microphones and other audio program sources, and a portable antenna. Remotes using portable antennas inside buildings have very limited range (typically less than one mile). If greater range is needed, consider locating the transmitting antenna outside the building at a height necessary to provide a line-of-sight path to the receiving antenna.
  • Page 15 8/7/2003 With the SRPT-30/40A TRANSMIT/STANDBY switch in “STANDBY” position, plug the transmitter into a grounded, three-prong, 110-120 or 220-240 VAC outlet. WARNING THE MANUAL SWITCH ON THE INTERNAL SWITCHING POWER SUPPLY IS SET AT THE FACTORY TO THE 115 POSITION IF THE ORDER WAS FOR 110-120 VAC.

    MICROPHONE, ANTENNA, OR OTHER CONNECTED EQUIPMENT) ARE STANDING ON WET GROUND OR CONCRETE. For locations where AC power is not available, the SRPT-30/40A can be powered from a fully charged automobile battery. Connect a portable antenna such as the Marti PAV/150, PAV-450, or YC-450 to the ANTENNA connector on the back of the transmitter.
  • Page 17 SRPT-30/40A Mobile Remote Control Remote control of the SRPT-30/40A transmitter requires a switch to control primary 12-15 VDC power (or 15-30 VDC) and a second switch to control the transmit function. The primary 12-15 VDC (or 15-30 VDC) control requirement can be met by tapping the ignition switch circuitry of the vehicle. The “transmit” function can be performed by installing a switch on the vehicle.

Marti typically uses the RACOM MODEL 1402 Automatic Morse Code Station Identifier to accomplish this task. Marti stocks and sells the RACOM 1402 (part number 565-006-1) along with the interconnecting cable (part number 585-088).

  • Page 21 FAILURE TO USE A PROPERLY GROUNDED OUTLET COULD RESULT IN A SAFETY HAZARD OR FAULTY EQUIPMENT PERFORMANCE. For fixed automatic repeater operation, connect Cable No. 585-143 (FIG. 4.) between accessory connectors of the receiver and SRPT-30/40A transmitter. Connect receiving antenna to receiver J6 and transmit antenna to SRPT- 30/40A ANTENNA connector.

    BASE STATION ANTENNA INSTALLATION CHECKLIST The following suggestions are offered to help those responsible for antenna installations avoid costly errors in assembly and adjustment. Marti Electronics assumes no responsibility for the installation and performance of antenna systems associated with its equipment. The following suggestions are not intended to be a complete step-by-step procedure, simply a listing of some of the most frequently reported errors in antenna system installation.
  • Page 23 8/7/2003 System Grounding It is essential that the RPU antenna system be properly grounded for safety and proper operation. Antenna Installation and Adjustment The polarization of the transmit and receive antennas of the RPU system must be the same! This means that if the transmitting antenna is vertical, the receiving antenna must also be vertical.

    External DC supply: The SRPT-30/40A can be powered externally by either a 12-15 Volt DC supply or a 15-30 Volt supply. If powered off a 12-15 Volt supply, connect three positive leads of the supply to pins 6, 7, and 14. Connect three negative leads of the supply to three ground pins (pins 1, 11, and 12).

AC LINE Switch, AC Receptacle & Fuse When the transmitter is not in use or if the SRPT-30/40A is to run off of an external supply, the AC LINE switch should be in the “OFF” position. When ready to use the SRPT-30/40A off of the AC line voltage, plug power cord into the AC Receptacle and switch the AC LINE switch to the “ON”...

F1/F2 Switch (SRPT-30 only) Switching to the F1 position will cause the transmitter to lock onto the frequency that was configured at the factory as “F1”.
  • Page 27 PA temperature is below 85 degrees C, it will turn off the HIGH TEMP LED and then enable the PA to transmit power. A HIGH TEMP alarm could be due to the fan malfunctioning, the SRPT-30/40A placed in a closed-in area with limited air circulation, or an experience of high VSWR.
  • Page 28 A miniature, single circuit, 1/8 inch, phone plug should be used with the MONITOR jack. POWER ADJUST Pot When the SRPT-30/40A is transmitting, this pot can be adjusted to increase or decrease the output power from the MAXIMUM power setting to almost zero Watts. TRANSMIT LED When the TRANSMIT/STANDBY switch is in the STANDBY position, the SRPT-30/40A will not transmit and the TRANSMIT LED will be off.

  • Page 29: Operation

    External DC Supply (12-15 Volt) Operation Make sure that the SRPT-30/40A is not connected to an AC line. Place the front panel AC LINE switch in the ON position. This turns off External DC Supply (12-15 Volt) to the unit.
  • Page 30 12 and 15 VDC. The unit should power up. From 16 to 20 VDC, the SRPT-30/40A will transmit up to 50 Watts RF output. From 20 to 30 VDC the SRPT-40A maximum output power will derate linearly down to 20 watts.
  • Page 31 Power-Up SRPT-30/40A If using AC line, turn on SRPT-30/40A by turning on front panel AC LINE switch. If using 12-15 Volt or 15-30 Volt external DC supply, turn on SRPT-30/40A by turning on external DC supply. Refer to the External DC Supply Operation procedure above for proper installation and operation.

    SRPT-30 Only: The SRPT-30 will power-up on frequency F1 or F2 depending on the position of the F1/F2 front panel switch. The frequencies corresponding to F1 and F2 were determined at the time of order and are hard coded within the synthesizer.
  • Page 33 450 band models. All other frequencies are considered non-standard frequencies. The SRPT-30/40A will lock on standard output frequencies within a ±.00004% tolerance. The SRPT-30/40A will lock on about 95% of non- standard frequencies. The tolerance of these frequencies fall within ±.00015% of the requested frequency. If the synthesizer determines that the non-standard frequency will fall outside ±.00015% of the requested frequency, then this...
  • Page 34 8/7/2003 Changing Output Frequency via Channel Select – SRPT-40A Only The frequency can also be changed by entering a channel number that was previously stored with a frequency. See Storing Output Frequencies into Channels for instructions on how to store frequencies. There are ten channels available for storing and recalling frequencies.
  • Page 35 8/7/2003 It would be a good idea to test the stored channel(s) by changing the frequency to some other frequency and then recalling the stored channel(s). Control Switch Settings – SRPT-40A Only Control Switch Settings enable or disable important controls used in the SRPT-40A. These control settings include the following: Power Adjust Pot HiHi VSWR Foldback...
  • Page 36 8/7/2003 setting is useful for locking out anyone from changing frequencies, or to change frequencies via user programmed channels. Channel Frequency Change – The default for this setting is “enabled” to be able to change the output frequency by channel select. If “disabled”, then attempting to change the output frequency by selecting channels will be ignored by the internal controller.

    10.0 volts to the audio and mixer boards. Therefore, the synthesizer will stay locked during most power surges and excessive voltage drops. The 800-392A also suppresses any external (or internal) voltage noise such as an alternator from a running vehicle. As a result, the SRPT-30/40A still maintains a high signal-to-noise. TRANSMITTER SYNTHESIZER Board, 800-375AT The fundamental purpose of this board is to accomplish two things: (1) Generate the final output frequency and (2) FM modulate the mixed audio.
  • Page 38 The output of T2 is fed into the final PA module (U3) for an output of up to 60 Watts max. This PA module usually has a lower RF output for SRPT-30’s. The signal is then low-passed filtered through FL1 and then fed through a directional coupler for monitoring forward and reflected power.
  • Page 39 8/7/2003 RF SYSTEM & CONTROL Refer to Block Diagram Drawing 702-117. The fundamental RF generation of the SRPT-30/40A takes place on the TRANSMITTER SYNTHESIZER board in a circuit known as a Phased-Locked Loop (PLL). The final output frequency (Fout) is generated by the Voltage Controlled Oscillator (VCO). Fout is determined by the Reference Frequency (Fr) and N by the relation: Fout = Fr x N.
