    J4–4 (signal) and J4–1 (ground). Once the audio cable is installed, connect the mating connector to the J4 receptacle on the rear–panel. CAUTION IF DC OPERATION IS REQUIRED, DO NOT APPLY MORE THAN +14V TO THE UNIT. ©2011 Broadcast Electronics...
  • Page 15 3. Ensure the receiver rear–panel ON/OFF switch is OFF. Connect the rear–panel AC line receptacle to an 85 to 264V, 47 to 63 Hz AC power source. USE ONLY A 3–PRONG GROUNDED OUTLET RECEPTACLE FOR SAFETY. The unit can also be operated from a +10V to +14V external dc supply. If DC operation is required, refer to Figure 1 and connect: 1) the positive wire to J4–7 and 2) ground to J4–8.

  • Page 17: Mobile Repeater Connections

    Mobile Repeater Connections A mobile repeater installation requires one of the following Receiver to Transmitter cables: For an RPT–15 Transmitter, use Cable No. 585–037–2 with 4 Amp fuse. For an SRPT–30/40A Transmitter, 12–15 VDC operation, use Cable No. 585–139. For SRPT–30/40A Transmitter, 15–30 VDC operation, use Cable No. 585–140. A mobile repeater installation also requires one of the following mobile mounting brackets: - For an SR–30/SR–40A receiver, use Mobile Mounting Bracket 700–252.
  • Page 18: Antennas

    Personnel must not be near the antenna when radiating. Locate antenna as far as possible from people and equipment susceptible to RF radiation. Do not mount antenna directly on transmitter. Refer to ANSI C95.1 “Limits on Non–Ionizing Radiation.” ©2011 Broadcast Electronics...
  • Page 19: Base Station Antenna Installation Checklist

    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, Inc. 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 20 Check VSWR of both transmit and receive antennas. VSWR should be less than 1.5:1. Check for obstructions in the path such as trees and man–made structures. The base antenna must be high enough to provide a line–of–sight path to the remote transmitting antenna. ©2011 Broadcast Electronics...
  • Page 21: Operation

    4 OPERATION CONTROLS AND INDICATORS 4.1.1 SIGNAL ATTENUATION CONTROL The SIGNAL ATTENUATION control adjusts a variable attenuator at the input of the converter. This control is designed to minimize the reception of unwanted signals during interference conditions. These conditions are due to extremely high intermodulation from a combination of neighboring signal frequencies.
  • Page 22 Lower the input signal level to the desired squelch point as viewed on the multimeter. Depress the SQUELCH LEVEL , section of the control until the UNSQUELCHED indicator extinguishes. Return the signal level to the normal level. ©2011 Broadcast Electronics...
  • Page 23 4.1.4 MULTIMETER The SR–30/SR–40A is equipped with a multimeter. The multimeter is controlled by the meter select switch. The following text presents a description of the multimeter switch positions. To use the multimeter, operate the switch to the desired position and view the indication on the meter. The green values on each meter scale present nominal values.
  • Page 24 The receiver audio can be monitored using the front–panel headphone receptacle and level control. A 1/4” inch stereo headphone receptacle is provided for headphone monitoring. A 40 Ohm or greater headphone impedance is required. Adjust the headphone level using the HEADPHONE LEVEL control. ©2011 Broadcast Electronics...
  • Page 25: Initial Start-Up And Operation

    INITIAL START–UP AND OPERATION The following text presents initial start–up and operating procedures. Apply power to the unit. The POWER indicator will illuminate. The AFC LOCK indicator will illuminate when the unit locks to a frequency. The UNSQUELCHED indicator will illuminate if the unit signal level is above the squelch point. The MAX SIG level indicator will illuminate if no attenuation is applied.
  • Page 26 To monitor the program audio, insert a stereo headphone jack into the HEADPHONE receptacle. Adjust the headphone level using the HEADPHONE LEVEL control. ©2011 Broadcast Electronics...
  • Page 27: Theory Of Operation

    5 THEORY OF OPERATION Refer to block diagram 597–8104–2 in the SCHEMATIC AND ASSEMBLY DRAWINGS section as required for the following discussion. Converter, 913–2132–150/–240/–330/–450/–950 The received RF signal is applied to the converter circuit board. This circuit board is: 1) assembled for specific bands of operation and 2) can accept a 50 MHz (30 MHz for 950 MHz units) wide group of frequencies within the specific band.
  • Page 28 IC2. When this voltage exceeds the reference voltage setting of R16 the comparator output goes high, turning on transistor Q1 and pulling in relay K1. Relay contacts are available at accessory connector J4 for low current switching and signaling. ©2011 Broadcast Electronics...
  • Page 29: Input/Output Filter, 800-193Ad

    Input/Output Filter, 800–193AD All input/output circuits connected to the accessory connector as well as the AC line input have radio– frequency filters. The filter circuitry is located on I/O Filter Schematic 800–193AD. Front Panel Circuit Board Assembly, 953–2130–001/–002 The front panel circuit board contains three switching power supply circuits, decode circuitry for the SR–40A frequency programming switches, the metering circuitry, and a digital–to–analog converter (DAC) circuit.
