SRPT-30 DUAL-CHANNEL RPU TRANSMITTER

SRPT-40A FREQUENCY AGILE RPU TRANSMITTER

Page 8

8/7/2003

The Marti Models SRPT-30/40A are wide-band – high power RPU Transmitters designed to operate in the Remote Pick-Up Broadcast Service as defined in Part 74, Subpart D, of the FCC Rules and Regulations. The SRPT-30 replaces the Marti RPT-30 series of RPU’s. Like its predecessor, the SRPT-30 has two frequency channels and a four-input mixer for mic/line audio. Unlike the RPT-30, the SRPT-30 uses synthesizer technology (not to be confused with frequency agile) instead of the discrete crystal technology. Also the SRPT-30 is equipped with a wide-band power amplifier that has a power output up to 30 watts that can be adjusted from the front panel. This, combined with the wideband synthesizer, benefits the operator in the following ways: (1) Frequency separation between F1 and F2 frequency can be up to 50 MHz and (2) No RF tuning required.

The SRPT-40A also uses synthesizer technology with a wide-band power amplifier and requires no tuning. It is frequency agile up to 50 MHz with a front-panel adjustable output power up to 60 watts in some models. The frequency can be “dialed in” from the front panel and will automatically tune precisely to all frequencies divisible by 5 KHz or

6.25 KHz increments. It will also tune to within ±.00015% tolerance of most other frequencies not divisible by 5 KHz or

6.25 KHz increments. Finally, the user may operate the SRPT-40A in channel mode where he may store and recall up to 10 frequencies.

Refer to the SPECIFICATIONS & ORDERING section for a listing of available frequency ranges and power models. These transmitters, when used with their recommended companion receiver, provide a remote broadcast link having audio quality not approached by conventional voice communication radio equipment. The SRPT-30/40A transmitters operate from 110-120 VAC or 220-240 VAC (manually switched internally), 50/60 Hz. The transmitters can also operate on 12-15 VDC or 15-30 VDC battery (or external supply) in fixed, portable, or mobile, service. Four audio input channels are provided with individual mixing gain controls. A meter and selector switch are provided for monitoring forward and reverse power, power supply voltage, PA current and audio compression.

SRPT-30/40A Features:

· Four balanced microphone mixing inputs, one switchable to balanced line level

· No RF tuning required

· Switching Power Supply operates on any AC voltage from 110-120 VAC or 220-240 VAC

· LEDs indicate High VSWR, Over-Temperature, AFC Lock, and Transmit

· Illuminated VU Meter for displaying Forward/Reverse Power, PA current, Power Supply

voltage, and Audio Compression

· Output power adjustable from front panel

· External 12-15 VDC or 15-30 VDC supply capability and external transmit control

· When operating on external 12-15 VDC supply, RPU will still remained locked for

external supply voltages as low as 7 VDC (Max power will de-rate linearly below 12 VDC)

· Fully suppresses external voltage supply noise such as car alternator

· High speed imbedded µ-controller to perform the following additional features:

· Power held constant over frequency, temperature, and voltage change

· High PA temp and VSWR warning indicators

· Auto frequency re-lock due to power outage

· Auto fold-back and recover due to high VSWR

· Auto shutdown due to very high PA temp – auto recover after cool down

· Auto shutdown due to open/short-output – auto recover

Page 14

8/7/2003

INSTALLATION

Install rack-mounted equipment in a well-ventilated, well-grounded, and shielded rack cabinet. Do not locate solid-state equipment in a rack above tube-type equipment, which produces high temperatures. It is highly recommended that if the equipment is mounted in a rack cabinet, a blower should be installed in the cabinet as well. Problems can also be avoided by locating this unit away from other equipment which has transformers that produce strong magnetic fields. These fields can induce hum and noise into the Marti equipment thus reducing performance. Strong radio-frequency (RF) fields should be avoided where possible. Extensive shielding and filtering have been incorporated into this equipment to permit operation in moderate RF environments. All equipment racks, cabinets, etc., should be bonded together by wide copper grounding strap to ensure that all system elements are at RF ground potential.

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. This may not be practical if a great length of coaxial cable is required. Many broadcasters are using the Marti mobile relay system to do remotes from inside buildings. This system consists of the originating transmitter with its antenna inside the building which transmits to a “mobile relay” parked outside the building. The mobile relay consists of a Marti Model AR-10 receiver and Marti RPT series transmitter with mobile antennas installed in a vehicle. The AR-10 receiver picks up the encoded signal originating from the RPT series transmitter located inside the building, automatically turns on the relay transmitter (on a different frequency), which re-transmits the program to the distant receiving antenna at the radio station studio or transmitter site. (Mobile relay equipment packages are available from Marti.)

Stationary Remote Installation Procedure

1. The transmitter is normally located near the announcer or engineer to permit access to gain controls, microphone

inputs, the monitor jack, and metering.

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.”

Page 15

8/7/2003

2. 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.

THE MANUAL SWITCH ON THE INTERNAL SWITCHING POWER SUPPLY IS SET AT THE

FACTORY TO THE 230 POSITION IF THE ORDER WAS FOR 220-240 VAC.

IF THE OPERATOR PLANS TO OPERATE THIS UNIT AT AN AC VOLTAGE DIFFERENT THAN

WHAT IS STATED ON ORDER, IT IS THE REPONSIBILITY OF THE PURCHASER TO SWITCH TO

THE APPROPRIATE POWER SUPPLY POSITION.

WARNING

DO NOT PLUG INTO AC WITHOUT FIRST KNOWING THE POSITION OF THE AC INPUT SWITCH

LOCATED ON THE SIDE OF THE INTERNAL POWER SUPPLY.

SEE AC LINE INPUT SELECTION – 110-120 VAC OR 220-240 VAC SUB-SECTION IN THE

CALIBRATION AND ADJUSTMENTS SECTION FOR VERIFICATION AND CHANGING.

WARNING

THIS EQUIPMENT MUST BE OPERATED WITH A 3-PRONG, GROUNDED, 110-120 OR 220-240

VOLT AC OUTLET RECEPTACLE!

FAILURE TO USE A PROPERLY GROUNDED OUTLET COULD RESULT IN A SAFETY HAZARD

OR FAULTY EQUIPMENT PERFORMANCE.

IF AN EXTENSION CORD IS USED, IT MUST BE THE THREE-WIRE GROUNDING TYPE TO

INSURE SAFETY.

Page 16

8/7/2003

WARNING

DO NOT CUT OFF THE GROUND PIN OF A 3-PRONG PLUG!

EXCESSIVELY LONG EXTENSION CORDS SHOULD BE AVOIDED SINCE THE VOLTAGE DROP

CAN DEGRADE EQUIPMENT PERFORMANCE.

DO NOT ALLOW THE SRPT-30/40A TO GET WET.

DO NOT OPERATE WHERE PERSONNEL TOUCHING THE TRANSMITTER (OR ITS

MICROPHONE, ANTENNA, OR OTHER CONNECTED EQUIPMENT) ARE STANDING ON WET

GROUND OR CONCRETE.

3. For locations where AC power is not available, the SRPT-30/40A can be powered from a fully charged automobile

battery.

4. 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.

Mobile Installation

The SRPT-30/40A transmitter can be installed in the vehicle where the TRANSMIT/STANDBY function can be operated directly, or the transmitter can be located elsewhere (in the trunk of a car or rear of a van) and controlled remotely. The choice depends upon the type of vehicle and the type of operation anticipated. The antenna(s) are usually mounted on top of the vehicle to provide maximum height.

Transmitter Mounting

1. Locate transmitter where vent holes on top and rear of unit are not obstructed. Leave enough space for the mic. Plug

on the front panel and the accessory plug on rear of unit.

2. Hook the four mounting fasteners (in retracted position in the four slots on the sides of the transmitter. See Fig. 1.

(Fasteners are in Mobile Mounting Kit, 700-252-2).

3. Mark the location of the two mounting holes in each fastener bracket. Drill 7/64” diameter holes into the mounting

surface at the marked places for #6 x 1/2” sheet metal screws.

4. Attach the mounting fasteners with the sheet metal screws provided. Secure the transmitter with the fasteners.

Receiver Mounting

For mobile repeat using the Marti AR-10 Mobile Repeat Receiver, mount the receiver near the transmitter using the three fasteners supplied in Mobile Mounting Kit, 700-252-2.

MOBILE MOUNT FASTENERS

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.

FIG. 2A and 2B show the electrical circuit of a mobile installation for 12-15 VDC (585-141) and 15-30 VDC (585-

142), respectively.

Mobile Repeat

Mobile repeat operation is covered under STATIONARY REMOTE BROADCAST INSTALLATION. Electrical connection for a 12-15 Volt supply is made through Mobile Repeat Cable No. 585-139. This cable is connected between the SRPT-30/40A transmitter and AR/CR-10 receiver. Power is obtained by connecting the fused RED wire to the 12-15 VDC battery or supply. The supply must be capable of delivering 10 Amps minimum. The electrical diagram of this cable is shown in FIG. 3A.

NOTICE

WHEN OPERATING THROUGH A CIGARETTE LIGHTER, THERE MAY BE A ONE TO TWO VOLT

DROP DUE TO THE LENGTH OF INTERNAL VEHICLE WIRING AND THE LARGE AMOUNT OF

CURRENT REQUIRED TO OPERATE THE SRPT-30/40A AT HIGHER OUTPUT POWERS.

THE SRPT-30/40A WILL OPERATE WITH AN EXTERNAL INPUT VOLTAGE AS LOW AS 7 VDC.

HOWEVER THE MAXIMUM RF OUTPUT POWER WILL DE-RATE LINEARLY AS THE EXTERNAL

INPUT VOLTAGE DROPS BELOW 12 VDC.

Electrical connection for a 15-30 Volt supply is made through Mobile Repeat Cable No. 585-140. This cable is connected between the SRPT-30/40A transmitter and AR/CR-10 receiver. Power is obtained by connecting the fused BLUE wire to the vehicle 15-30 VDC battery or supply. The supply must be capable of delivering 10 Amps minimum. The electrical diagram of this cable is shown in FIG. 3B.

Automatic Morse Code Station Identifiers

The SRPT30/40A-450T TSL RPU’s are used for sending data back from a transmitter site to the studio (also known as telemetry). In older FCC requirements, un-manned transmitters required an automatic remote control system to send data back to the studio for verifying that the transmitter was operating properly. Many broadcasters today are still using

Page 18

8/7/2003

this system. Along with the data, a station identifier in morse code can also be input into the TSL. 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). Typically, the cable is connected to the RACOM 1402 at the Marti facility. The customer can also connect up the cable as well. Refer to Drawing 702-125.

Mobile Antenna Installation

One or more mobile antennas are required depending upon the various receive and transmit frequencies and whether antenna duplexing is used. Antennas are specified in the various system packages listed in the Marti literature. The installer should follow the instructions supplied with the mobile antennas.

ANTENNAS

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.

Antenna Assembly

Follow the manufacturer's instructions carefully. If no instructions were included with the antenna, call or write the antenna manufacturer for instructions. Antennas which have phasing or stacking cables must be assembled carefully to avoid phase reversal or signal cancellation.

Transmission Line Connector Assembly

Do not use RG-58 U or RG-8 U cable for STL station antennas! They have too much loss at VHF and UHF frequencies. Follow the instructions furnished by the manufacturer when cutting coaxial cable. Inspect the cable ends for small metal fragments which can short-circuit the line inside the connector assembly. Check the line for a shortcircuit condition after each connector is installed by using an ohmmeter. Pressurized line should be checked for several days under pressure before installation on a tower to ensure that there are no leaks in the line or fittings.

Moisture Proofing Coax Connectors and Fittings

Extreme care must be exercised with coaxial cable before and after connectors have been installed to ensure that moisture does not enter the line. Foam dielectric line can take on moisture absorption which is difficult to detect and remedy. Therefore, keep the line dry while in storage with ends tightly capped. Coaxial splices, connectors, and fittings, to be located outside should be made mechanically tight, then coated with a weather-proofing material over at least two layers of vinyl plastic electrical tape. Moisture problems in antenna systems are usually traced back to connectors which have NOT been properly taped. The Marti K-1 Grounding and Weatherproofing Kit is recommended for use in each new antenna installation.

Location and Grounding of Coaxial Cable

Keep the RPU receiver coaxial cable as far from the broadcast transmitter and its coaxial cable as possible.

WARNING

DO NOT STRAP RECEIVER CABLE TO THE MAIN ANTENNA CABLE AT ANY POINT.

PLACE THE RECEIVER ANTENNA COAXIAL CABLE ON THE OPPOSITE SIDE OF THE TOWER

FROM THE MAIN ANTENNA CABLE.

Maintain maximum separation between these cables at all points, including the distance from tower base to transmitter building as well as inside the building.

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. Each antenna should be attached to the tower using the proper side mount or top mount hardware. If an RF wattmeter is available, each antenna and transmission line can be checked for VSWR when the transmitter is supplying power to it. The VSWR should be less than 1.5 to 1 (1.5:1).

If the antenna system fails to give the predicted signal strength level, the following items should be checked:

1. Check for correct assembly of antenna.

2. Check that antennas have same polarity.

3. Check VSWR of both transmit and receive antennas. VSWR should be less that 1.5:1.

4. 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.

CAUTION & WARNING

YOU CAN BE KILLED IF AN ANTENNA COMES IN CONTACT WITH ELECTRIC POWER LINES

OR EXPOSED ELECTRICAL WIRING.

FOR YOUR SAFETY, USE EXTREME CAUTION WHEN IN-STALLING ANTENNAS.

KEEP AWAY FROM POWER LINES.

CONTROL, LED, & CONNECTOR FUNCTIONS

ACCESSORY Input Connector

Audio Input:

When Input 4 is switched to “HI” level, audio can be fed into pins 4 and 5 of the ACCESSORY connector on the rear of the transmitter. Input level should be between 0.2 volts to 2.0 volts rms. The output impedance of the device connected to Input 4 should be 8 - 600 ohms. For unbalanced operation ground pin 5 to pin 1, 8, 11, or 12 and connect audio to pin 4. Use standard 15-pin “subminiature D” female connector with cover.

Transmit Control:

“TRANSMIT” control can be accomplished remotely by a switch circuit connected between pin 15 and one of the available ground pins (pin 1, 8, 11, or 12).

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). Each of the three positive leads and each of the three negative leads should be an 18 gauge wire. You may also use one 12 gauge wire for each positive and negative leads and split the stranded ends into three at the connector end.

ATTENTION

FOR 12-15 VOLT EXTERNAL SUPPLY, THE OPTIMUM VOLTAGE IS FROM 12 TO 15 VOLTS.

APPLYING A VOLTAGE LOWER THAN 12 VOLTS, WILL LIMIT THE MAXIMUM RF OUTPUT

POWER.

ALSO, THE EXTERNAL BATTERY OR POWER SUPPLY SHOULD BE CAPABLE OF HANDLING A

CONSTANT 10 AMPS. THERE WILL BE A DROP IN VOLTAGE ACROSS THE POWER CABLES.

THE POWER CABLES SHOULD BE AS SHORT AS POSSIBLE AND AS HEAVY GAUGE AS

POSSIBLE. EXPECT A COUPLE OF VOLTS DROP WHEN OPERATING THROUGH A CIGARETTE

LIGHTER.

If powered from a 15-30 Volt supply, connect three positive leads of the supply to three 15-30VDC pins (pins 2, 3, and 10). Connect three negative leads of the supply to three ground pins (pins 1, 11, and 12). Each of the three positive leads and each of the three negative leads should be an 18 gauge wire. You may also use one 12 gauge wire for each positive and negative leads and split the stranded ends into three at the connector end.

ATTENTION

FOR 15-30 VOLT EXTERNAL SUPPLY, IF APPLYING A VOLTAGE LESS THAN 16 VDC, THE

SRPT-30/40A EXTERNAL B+ ADJUST POT ON THE TWO-STAGE RF POWER AMPLIFIER BOARD

SHOULD BE ADJUSTED TO ABOUT 12 VDC.

IF THIS IS THE CASE, THE MAXIMUM RF OUTPUT POWER COULD BE LIMITED.

Page 25

8/7/2003

CAUTION & WARNING

NEVER INSTALL AND CONNECT THE 12-15 VOLT AND THE 15-30 VOLT SUPPLIES AT THE

SAME TIME.

ALSO, NEVER CONNECT THE 15-30 VOLT SUPPLY TO THE 12-15 VOLT PINS AND NEVER

CONNECT THE 12-15 VOLT SUPPLY TO THE 15-30 VOLT PINS.

DOING SO MAY DAMAGE THE INTERNAL SWITCHING SUPPLY OR EITHER OF THE

EXTERNAL DC SUPPLIES.

CAUTION & WARNING

NEVER CONNECT THE SRPT-30/40A TO THE AC LINE AND EITHER OF THE EXTERNAL DC

SUPPLIES AT THE SAME TIME.

DOING SO MAY DAMAGE THE INTERNAL SWITCHING SUPPLY OR THE EXTERNAL DC

SUPPLY.

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” position.

The AC line fuse is rated at 2.5 amps.

WARNING

DO NOT PLUG INTO AC WITHOUT FIRST KNOWING THE POSITION OF THE AC INPUT SWITCH

LOCATED ON THE SIDE OF THE INTERNAL SWITCHING POWER SUPPLY.

SEE AC LINE INPUT SELECTION – 110-120 VAC OR 220-240 VAC SUB-SECTION IN THE

CALIBRATION AND ADJUSTMENTS SECTION FOR VERIFICATION AND CHANGING.

AFC LOCK LED

The AFC LOCK LED will either be flashing or solid green at all times, except during initial power up – and in that case it will only be off for a few seconds.

When the SYNTHESIZER is searching for a frequency to lock on to and is therefore not locked, the AFC LOCK LED will flash green. When the SYNTHESIZER finds and locks onto the frequency it was searching for, the AFC LOCK LED will stay on, solid green. Three seconds after the SYNTHESIZER becomes locked, it will then be ready and will enable the transmitter to output power.

Page 26

8/7/2003

In normal conditions, the SYNTHESIZER will not come “unlocked” unless sent a command to change to change to a new frequency. However, other conditions can cause the SYNTHESIZER to come unlocked such as an AC line surge or a sudden and very large change in VSWR. In those cases, the SYNTHESIZER will re-lock back on the assigned frequency. The AFC LOCK LED will flash green until the SYNTHESIZER is locked. Once the SYNTHESIZER is locked it will stay on, solid green.

ANTENNA Connector

Connection of various antenna systems is covered under INSTALLATION and ANTENNAS. It is only necessary for the operator or announcer to see that the ANTENNA connector is tight and that the antenna is clear of objects which may affect its radiation efficiency.

CAUTION & WARNING

THE ANTENNA CONNECTOR IS A TYPE “N” FEMALE CONNECTOR AND REQUIRES A MATING

TYPE “N” MALE CONNECTOR.

PLUGGING IN A “UHF TYPE (PL-259 OR SO-239)” INTO THE ANTENNA CONNECTOR WILL

DAMAGE AND SHORT OUT THE ANTENNA CONNECTOR. THIS COULD BURN UP THE PA

MODULE AND OTHER INTERNAL COMPONENTS.

ENCODE Switch

The internal subaudible encoder can be switched “ON” or “OFF” by the front panel switch. Encoding is used to activate a repeater station, tape recorder, etc.

FREQUENCY SELECT Pushwheel Switches and EXECUTE Switch (SRPT-40A only)

Dial in the numbers that represent a frequency, channel number, or other command using the FREQUENCY SELECT Pushwheel switches. Then press and release the EXECUTE switch to “send” the command numbers on the FREQUENCY SELECT pushwheel switches to the internal controller to be decoded and executed. See the OPERATION section for a listing and understanding of all commands.

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”. Switching to the F2 position will cause the transmitter to lock onto the frequency that was configured at the factory as “F2”. The F1 and F2 frequencies are selected by the purchaser at the time of order.

AUDIO GAIN Controls

The GAIN potentiometer located above each input connector provides an independent level adjustment for that input. Each GAIN potentiometer is adjusted as follows:

1. Connect input source at normal audio level.

2. Turn GAIN potentiometer to maximum counter-clockwise (“OFF”) position.

3. Place TRANSMIT/STANDBY switch in “STANDBY” position and allow METER pointer to reach 0 VU. Slowly

increase gain (clockwise) until METER begins deflecting to the left on audio peaks. Maximum deflection should be

-3 to -5 VU on the METER scale. This indicates 100% modulation of the transmitter. Excessive gain settings cause

high compression values which result in annoying increase in background noise. A 600 ohm headset may be

Page 27

8/7/2003

plugged into the MONITOR jack to aid in arriving at the proper gain adjustment. In high noise environments, close-

talk the microphone and reduce MIC gain until a maximum of -2 VU gain-reduction is indicated.

4. Once the proper gain level is determined, it will not be necessary to change it for that particular microphone or tape

player. The broadcast quality compressor/limited built into the unit will maintain modulation at the maximum level

while preventing over-modulation.

HIGH TEMP LED

When the internal controller detects a PA temperature between 85 and 100 degrees C, the HIGH TEMP LED will flash red at a rate of once per second.

When the internal controller detects a PA temperature of greater than 100 degrees C, the RF output power will completely shutdown, and the HIGH TEMP LED will flash red at a rate of twice a second. The RF output power will stay shutdown until the PA temperature has dropped below 85 degrees C. When the internal controller detects that the 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.

HIGH VSWR LED

When the internal controller detects a VSWR of greater than 2 but less than 4, the HIGH VSWR LED will flash red at a rate of once per second.

When the internal controller detects a VSWR of greater than 4 but less than 6, the output power will limit to a maximum of half the rated power (that was set using the MAX PWR pot (R74) located on the synthesizer – see TUNE- UP and ADJUSTMENTS section) and the HIGH VSWR LED will flash red at a rate of twice per second. When the detected VSWR falls less than 4, the output will resume to it’s previous power setting, the HIGH VSWR LED will flash at a rate of once per second if VSWR greater than 2, and will turn off if VSWR is less than 2.

When the internal controller detects a VSWR of greater than 6, or detects a reverse power of greater that one-third the maximum rated output power, the output power will immediately shut off, the TRANSMIT LED will flash red, and the HIGH VSWR LED will flash rapidly. Every three seconds the controller will attempt to turn on the transmit output but will again shut down if the conditions have not changed. If this occurs, even if the operator turns off the TRANSMIT switch, the HIGH VSWR LED will still flash rapidly. The only way to stop the HIGH VSWR LED from flashing, is to repair the output (i.e., loose connection of output, wrong connector type, wrong cable, faulty antenna, short circuit cable, etc…), and then turn the TRANSMIT switch on (if it was off), and after 3 seconds if the controller does not detect a very high VSWR or high reverse power, the transmit output power will come on.

METER and METER SELECT Knob

When the METER SELECT Knob is either in the FORWARD POWER or REVERSE POWER position, the corresponding measurement can be read off of the top "WATTS" scale of the METER.

When the METER SELECT knob is either in the PA CURRENT or the B+ position, the corresponding measurement can be read off of the middle “VOLTS/AMPS” scale of the METER.

When the METER SELECT knob is in the AUDIO COMPRESSION position, the corresponding measurement can be read off of the bottom “VU” scale of the METER.

Page 28

8/7/2003

MIC Input Connectors

These balanced inputs are for a 150 ohm dynamic microphone such as the Shure BG 1.0 with standard XLR-3 or A3M connector. Microphone connections are given in INSTALLATION.

Input 4 can operate at MIC LEVEL or HIGH LEVEL by means of a SELECTOR switch inside the transmitter just behind the Input 4 pot. The unit is factory selected for “HI” (HIGH) LEVEL balanced input for use with tape machines, etc. To convert Input 4 to MIC (microphone) LEVEL, remove top cover and move switch to “MIC”.

MONITOR Jack

The MONITOR jack is active in “STANDBY” and “TRANSMIT” positions of the TRANSMIT/STANDBY switch. A high-quality headset having 300 ohms or higher impedance can be plugged into the MONITOR jack to make adjustments or to monitor the quality of the audio being transmitted. 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.

When the TRANSMIT/STANDBY switch is in the TRANSMIT position but the SYNTHESIZER is not ready, the SRPT-30/40A will not transmit and the TRANSMIT LED will flash red.

When the TRANSMIT/STANDBY switch is in the TRANSMIT position and the SYNTHESIZER is ready (which is always three seconds after the SYNTHESIZER becomes locked), the SRPT-30/40A will transmit and the TRANSMIT LED will be on, solid red.

TRANSMIT/STANDBY Switch

This switch is placed in “STANDBY” position to shut off the output power. The synthesizer will still be locked on frequency as indicated by the solid AFC LOCK LED. The TRANSMIT/STANDBY switch is placed in the “TRANSMIT” position when transmission is desired. The output power will turn on immediately at an output power that correlates to the POWER ADJUST position. The TRANSMIT/STANDBY switch should be returned to the “STANDBY” position as soon as a transmission is completed.

OPERATION

Connect up SRPT-30/40A to the AC Line Receptacle or External DC Supply

CAUTION & WARNING

NEVER CONNECT THE SRPT-30/40A TO THE AC LINE AND EITHER OF THE EXTERNAL DC

SUPPLIES AT THE SAME TIME.

DOING SO MAY DAMAGE THE INTERNAL SWITCHING SUPPLY OR THE EXTERNAL DC

SUPPLY.

AC Line Operation

Position AC LINE switch to “OFF”, then plug SRPT-30/40A into a 110-120 VAC (if internal supply switched to

115) or 220-240 VAC (if internal supply switched to 230), grounded, 3-prong receptacle.

WARNING

DO NOT PLUG INTO AC WITHOUT FIRST KNOWING THE POSITION OF THE AC INPUT SWITCH

LOCATED ON THE SIDE OF THE INTERNAL POWER SUPPLY.

SEE AC LINE INPUT SELECTION – 110-120 VAC OR 220-240 VAC SUB-SECTION IN THE

CALIBRATION AND ADJUSTMENTS SECTION FOR VERIFICATION AND CHANGING.

WARNING

THIS EQUIPMENT MUST BE OPERATED WITH A 3-PRONG, GROUNDED, 110-120 or 220-240 VAC

RECEPTACLE!

FAILURE TO USE A PROPERLY GROUNDED OUTLET COULD RESULT IN A SAFETY HAZARD

OR FAULTY EQUIPMENT PERFORMANCE.

IF AN EXTENSION CORD IS USED, IT MUST BE THE THREE-WIRE GROUNDING TYPE TO

INSURE SAFETY.

DO NOT CUT OFF THE GROUND PIN OF A 3-PRONG PLUG!!

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

8/7/2003

The external supply or battery must be capable of delivering 8/10 Amps if running the SRPT-30/40A at maximum output power. Connect up the unit using the Marti 585-141 12-15 VDC External Supply Cable. If choose to build your own cable then follow the drawing on Figure 2A: Connect three positive leads of the supply to pins 6, 7, and 14 of a 15pin female D connector. Connect three negative leads of the supply to three ground pins (pins 1, 11, and 12) of the 15pin female D connector. Each of the three positive leads and each of the three negative leads should be an 18 gauge wire. You may also use one 12 gauge wire for each positive and negative leads and split the stranded ends into three at the connector end.

ATTENTION

FOR 12-15 VOLT EXTERNAL SUPPLY, THE OPTIMUM VOLTAGE IS FROM 12 TO 15 VOLTS.

APPLYING A VOLTAGE LOWER THAN 12 VOLTS, WILL LIMIT THE MAXIMUM RF OUTPUT

POWER.

ALSO, THE EXTERNAL BATTERY OR POWER SUPPLY SHOULD BE CAPABLE OF HANDLING A

CONSTANT 10 AMPS. THERE WILL BE A DROP IN VOLTAGE ACROSS THE POWER CABLES.

THE POWER CABLES SHOULD BE AS SHORT AS POSSIBLE AND AS HEAVY GAUGE AS

POSSIBLE. EXPECT A COUPLE OF VOLTS DROP WHEN OPERATING THROUGH A CIGARETTE

LIGHTER.

It is best to have an external switch between the external supply and the unit. Make sure the switch is in the open position before connecting it to external supply. Otherwise make sure that when connecting the positive lead to the external source that the 15-pin D connector is not connected to the SRPT-30/40A.

With the front panel AC LINE switch in the ON position, plug in the 15-pin D connector into the ACCESSORY connector located in the rear of the SRPT-30/40A. Turn on external supply (if have a switch). With a voltmeter, measure the voltage on the output of the external supply insuring that it is between 12 and 15 VDC. Switch the front panel AC LINE switch to the OFF position. The unit should power up.

External DC Supply (15-30 Volt) Operation

Make sure that the SRPT-30/40A is not connected to an AC line. The front panel AC LINE switch does not control the External DC Supply (15-30 Volt) operation. Therefore it does not matter what position it is in.

The external supply or battery must be capable of delivering 8/10 Amps if running the SRPT-30/40A at maximum output power. Connect up the unit using the Marti 585-142 15-30 VDC External Supply Cable. If choose to build your own cable then follow the drawing on Figure 2B: Connect three positive leads of the supply to three 15-30VDC pins (pins 2, 3, and 10). Connect three negative leads of the supply to three ground pins (pins 1, 11, and 2). Each of the three positive leads and each of the three negative leads should be an 18 gauge wire. You may also use one 12 gauge wire for each positive and negative leads and split the stranded ends into three at the connector end.

Plug in the 15-pin D connector into the ACCESSORY connector located in the rear of the SRPT-30/40A. Turn on external supply (if have a switch). With a voltmeter, measure the voltage on the output of the external supply insuring that it is between 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

8/7/2003

CAUTION & WARNING

NEVER INSTALL AND CONNECT THE 12-15 VOLT AND THE 15-30 VOLT SUPPLIES AT THE SAME TIME.

ALSO, NEVER CONNECT THE 15-30 VOLT SUPPLY TO THE 12-15 VOLT PINS AND NEVER CONNECT THE

12-15 VOLT SUPPLY TO THE 15-30 VOLT PINS.

DOING SO MAY DAMAGE THE INTERNAL SWITCHING SUPPLY OR EITHER OF THE EXTERNAL DC

SUPPLIES.

Connect up Antenna

Connect antenna to the ANTENNA connector on the SRPT-30/40A rear panel. Connection of various antenna systems is covered under INSTALLATION and ANTENNAS.

CAUTION & WARNING

THE ANTENNA CONNECTOR IS A TYPE “N” FEMALE CONNECTOR AND REQUIRES A MATING

TYPE “N” MALE CONNECTOR.

PLUGGING IN A “UHF TYPE (PL-259 OR SO-239)” INTO THE ANTENNA CONNECTOR WILL

DAMAGE AND SHORT OUT THE ANTENNA CONNECTOR. THIS COULD BURN UP THE PA

MODULE AND OTHER INTERNAL COMPONENTS.

CAUTION

DO NOT TURN ON AC LINE OR EXTERNAL DC POWER UNTIL ANTENNA HAS BEEN

PROPERLY CONNECTED TO ANTENNA CONNECTOR!

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.

The SRPT-30/40A will begin a power-up routine. The front panel meter will illuminate immediately. After about three seconds the AFC LOCK LED will begin flashing green indicating that the synthesizer is searching for the last frequency it was last locked on to.

If the TRANSMIT/STANDBY switch is in the TRANSMIT position, the TRANSMIT LED will flash red in unison with the green flashing AFC LOCK LED. Once the synthesizer has found and locked onto the frequency, the AFC LOCK LED will immediately stay on solid green and the TRANSMIT LED will continue to flash red for three additional seconds. After the three seconds, the SYNTHESIZER will be ready, will enable the power amplifier to transmit RF power, and the TRANSMIT LED will stay on solid red.

Page 32

8/7/2003

If the TRANSMIT/STANDBY switch is in the STANDBY position, the TRANSMIT LED and hence, the transmitter RF power, will be off and will stay off even after the SYNTHESIZER has locked and the AFC LOCK LED has illuminated solid green. When the TRANSMIT/STANDBY switch is placed in the TRANSMIT position (and three seconds have elapsed since the SYNTHESIZER became locked) the PA will immediately begin transmitting and the TRANSMIT LED will illuminate solid red.

Adjusting Output Power

Turn the METER CONTROL knob to the FORWARD POWER position and observe the forward power reading on the top scale of the METER. Using a small flat-head screwdriver, adjust the POWER ADJUST pot (located about ¾ of an inch behind the POWER ADJUST bezel ring) to adjust the forward power to a desired output power as indicated on the METER.

What Frequency Will the SRPT-30/40A Power-Up on?

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.

SRPT-40A Only:

The SRPT-40A will always power up on the last frequency it was locked onto before last power-down. If you’re not sure what frequency the SRPT-40A will power up on, first make sure that the POWER ADJUST pot is at a minimum (turned fully counter-clockwise) before powering up the SRPT-40A. After the SYNTHESIZER is locked and the TRANSMIT/STANDBY switch is set in the TRANSMIT position, monitor the RF output with a frequency counter. If necessary, increase the POWER ADJUST pot (turn clockwise) slowly until the frequency counter registers a frequency reading.

WARNING

NEVER CONNECT THE FREQUENCY COUNTER DIRECTLY TO THE RF OUTPUT CONNECTOR

OF THE SRPT-30 OR SRPT-40A.

THE FREQUENCY COUNTER SHOULD BE COUPLED OFF OF AN RF COUPLER OR A WATT

METER.

EXCEEDING THE INPUT POWER RATING OF THE FREQUENCY COUNTER COULD DO

INTERNAL DAMAGE TO IT.

Inputting Audio

Plug in microphones (Inputs 1 - 3) or tape player (Input 4 internally switched to “HI” position; See MIC Input Connections, above) and check operation by setting the METER CONTROL knob to the AUDIO COMPRESSION position and observing the compression on METER and by a headset plugged into MONITOR jack. Set AUDIO GAIN controls paragraph in the CONTROL & CONNECTOR FUNCTIONS section for how to adjust for no more than -3 VU audio compression on the METER.

Page 33

8/7/2003

Changing Output Frequency Direct

SRPT-30 Only:

Simply change the position of the F1/F2 front panel switch and the unit will change to the corresponding frequency.

SRPT-40A Only:

To change the frequency of the SRPT-40A, the S1 dip-switches on the Front Panel Control & Meter board (800385A) behind the front panel (see the SRPT-40A Adjustment Locations) need to be set with switches 1 and 2 in the “ON” position and switches 3 and 4 in the “OFF” position. These positions are the normal position and are set at the factory, so there should be no need to remove the top cover.

When the S1 switches are set as described in the last paragraph, then all that is required is to enter the desired frequency from left to right into the FREQUENCY SELECT pushwheel switches and then press and release the EXECUTE pushbutton switch.

All seven digits on the front panel FREQUENCY SELECT pushwheel switches must be entered. The frequency is entered in MHz where the first three digits represent the left side of the decimal place, and the last four digits represent the right side of the decimal place. For example, the frequency 450.0125 MHz will simply be entered as 4500125.

If a valid frequency is entered and the EXECUTE pushbutton is pressed and released, then the RF output power will immediately turn off (if it was on to begin with) and the SYNTHESIZER will go through it’s normal routine in searching and locking onto the requested frequency. When the frequency is found, the AFC LOCK LED will stop flashing and illuminate solid green. After three seconds the TRANSMIT LED will stop flashing and illuminate solid red (assuming the TRANSMIT/STANDBY switch is in the TRANSMIT position) and the SRPT-40A will resume transmitting at the new frequency and at the same output power it was before leaving the previous frequency.

What is A Valid Output Frequency?

A valid output frequency is defined as a frequency that operates within the model bandwidth and is either a standard frequency, or is a non-standard frequency that falls within ±.00015% of the requested frequency. A standard output frequency is one that is divisible by 5 or 6.25 KHz for 450 band models and less, and divisible by 10 or 12.5 KHz for greater than 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 nonstandard 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 is considered an invalid frequency and it will not change to the requested frequency.

SRPT-30 Only:

There are only two frequencies to choose from, F1 and F2, as configured at the factory, and are always considered valid. However, at the time of order, if the customer requires a frequency that is not divisible by 5 or 6.25 KHz (or by 10 or 12.5 KHz for > than 450 MHz models), we can determine immediately whether or not the requested frequencies will fall within ±.00015% tolerance. If one or both frequencies do fall not within this tolerance, then the order will be considered special and must be determined by the engineering department at Broadcast Electronics if we can tune to the required frequencies.

SRPT-40A Only:

If an invalid frequency is entered in, or if the same frequency that the SRPT-40A is currently locked on to is entered in, then the SRPT-40A will remain at its current frequency, i.e., nothing will happen. If the operator desires to change to a frequency that is invalid, he must choose the closest valid frequency and then manually tune the reference oscillator on the synthesizer to get to desired frequency. However, if the operator tunes the reference oscillator to get to an invalid frequency, then when needing to change to another frequency (valid or non-valid), the operator may have to retune the reference oscillator again.

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. These ten channels are preset with default or customer requested frequencies at the factory.

To change frequency via channel select, the S1 dip-switches behind the front panel must be set with switches 1 and 2 in the “ON” position and 3 and 4 in the “OFF” position. These are the default positions and are in the same position as when changing the frequency direct. So there’s no need to remove the top cover.

Now you’re ready to enter the channel. This is done by setting the six left-most digits (digits 2-7) of the FREQUENCY SELECT pushwheel switches equal to zero. Then the far right digit (digit 1) is set to the channel of choice (channel 0 – channel 9). After entering the channel, press the EXECUTE pushbutton down and then release. The SYNTHESIZER will change to the frequency that was stored in the channel.

WARNING

THE REMAINING OPERATIONS ARE FEATURES THAT REQUIRE SETTING INTERNAL DIP-

SWITCHES.

IN ALL CASES, WHEN PERFORMING THESE OPERATIONS, THE SRPT-40A MUST BE ON AND

THE TOP COVER MUST BE REMOVED.

WHEN THE OPERATION IS COMPLETE, ALWAYS SET THE INTERNAL S1 DIP-SWITCHES WITH

SWITCHES 1 AND 2 “ON” AND SWITCHES 3 AND 4 “OFF”. THEN RE-INSTALL THE TOP COVER.

Storing Output Frequencies into Channels – SRPT-40A Only

The SRPT-40A must be locked on a frequency before storing that frequency into one of the ten available channels. It is not necessary, however, that the SRPT-40A be transmitting, hence the TRANSMIT/STANDBY switch can be in STANDBY.

First, lock on to the desired frequency either directly or via channel select. Remove the top cover of the SRPT-40A. Set the S1 dip-switches (located behind the front panel) as follows: Switches 1, 3, and 4 set to the “OFF” position and switch 2 set to the “ON” position.

Next, set the six left-most digits (digits 2-7) of the FREQUENCY SELECT pushwheel switches equal to zero. Then the far right digit (digit 1) is set to the channel of choice (channel 0 – channel 9) to be stored. After entering the channel, press the EXECUTE pushbutton down and then release. The current frequency-in-lock will be stored in the selected channel and the SRPT-40A will remain at its current frequency. If you need to store more channels, repeat the steps in this paragraph.

Finally, put the S1 dip-switches back to where they were, i.e., switches 1 and 2 in the “ON” position and switches 3 and 4 in the “OFF” position. Re-install the top cover.

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 Reverse Power Calibration Forward Power Calibration HiHi Temperature Shutdown Direct Frequency Change Channel Frequency Change

Refer to TABLE (1) - Control Switch Settings Command for disabling or enabling the desired controls. Remove the top cover. Set the internal dip-switch S1 switches and the FREQUENCY SELECT pushwheel decimals as outlined in Table (1). The entries in BOLD are default settings from the factory

When all FREQUENCY SELECT pushwheel decimals have been set to their required values that correspond to the desired control switch setting, you must send the command by pressing the EXECUTE pushbutton down and then releasing. The internal controller will enable or disable the control. Set the internal dip-switch S1 back to its normal position with switch 1 and 2 “ON” and switch 3 and 4 “OFF”. Re-install top cover.

Following is a description of the control settings:

Power Adjust Pot – The default for this setting is “enabled” which allows the user to change the power from almost 0 Watts to the maximum RF output power setting via the front panel POWER ADJUST pot. Refer to the Maximum Power Setting paragraph in the CALIBRATION AND ADJUSTMENTS section of this manual for information on how to set the maximum power. If this user “disables” this setting, then the RF output power will maintain where last set and tuning of the POWER ADJUST pot will have no effect.

HiHi VSWR Foldback – The default for this setting is “enabled”. This means when a VSWR is detected greater than 4, the power will limit to one-half the maximum power setting. If VSWR foldback is “disabled”, then the forward RF power will not try to foldback, even when the controller detects a VSWR of greater than 4. The HIGH VSWR LED will still flash however. For maintaining long life from the power amplifier, it is not recommended to disable VSWR Foldback.

Reverse Power Calibration – The default setting for this setting is “disabled”. This setting should only be “enabled” during calibration (see the Reverse Power Calibration paragraph in the CALIBRATION AND ADJUSTMENTS section).

Forward Power Calibration – The default setting for this setting is “disabled”. This setting should only be “enabled” during calibration (see the Forward Power Calibration paragraph in the CALIBRATION AND ADJUSTMENTS section).

HiHi Temperature Shutdown – The default for this setting is “enabled”. See High Temp LED paragraph in the CONTROL & CONNECTOR FUNCTIONS section for complete description. When enabled, the power amplifier will shut down when the PA temp reaches 100 degrees C. If “disabled”, then the power amplifier will not shutdown due to HiHi temperature but the HIGH TEMP LED will still flash. Again, for maintaining long life from the power amplifier, it is not recommended to disable High Temperature Shutdown.

Direct Frequency Change – The default for this setting is “enabled” to be able to change the output frequency direct. If “disabled”, then attempting to change the output frequency will be ignored by the internal controller. This

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. This setting is typically “disabled” if the Direct Frequency Change setting is also disabled. In that case, only one frequency can ever be transmitted.

CIRCUIT BOARD DESCRIPTION

PRE-AMP/MIXER Board, 800-251A

Each of the four microphone inputs is fed to a low-noise differential op-amp (half of an NE-5532). Critical resistors in the input circuits are low-noise, precision, temperature stable types to obtain maximum performance from the preamps. Monolithic chip capacitors are used to filter RF voltages that may be present at the microphone inputs. The four op-amp outputs are fed to gain pots then resistively mixed and routed to the COMPRESSOR BOARD.

COMPRESSOR Board, 800-166A (SRPT30/40A-xxx: uses 800-166A40A;

SRPT30/40A-450T: uses 800-166A40ATSL)

Several functions are performed on this board. Integrated Circuit IC-1 serves as a (a) pre-amp (not used on the SRPT-30/40A), (b) pre-emphasis amplifier, (c) voltage-controlled attenuator, and (d) regulator /ripple rejection. Preemphasized audio out of IC-1B is also fed to D2 - D3 which form an adjustable series peak-limiting circuit. This circuit is adjusted to limit only audio peaks which get past the compressor. The limiter circuit feeds a low-pass filter (L1, C23, and R46) which reduces the audio bandwidth to that specified for the operating channel of the transmitter. To this is mixed the output of the tone encoder, IC-2A, which is a low-distortion Wien bridge oscillator. This composite signal is then fed to the Modulation port (on P2) of the Transmitter Synthesizer Board, 800-375AT. This audio signal is also fed to IC-2B which amplifies it to a level suitable for a 600 ohm headphone monitor. IC-2C is a DC amplifier the input of which is connected to the AGC (automatic gain control) circuit and the output of which drives the audio compression meter.

14.5 VOLT STEP-UP REGULATOR Board, 800-392A

The 800-392A is a DC/DC converter that powers the synthesizer, audio, and mixer boards. It allows the user to apply an external input voltage (through the 12-15 VDC accessory input pins) as low as 7 VDC and still maintain 14.5 volts to the synthesizer and 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. The circuitry to achieve this consists of a Phase-Locked Loop (PLL), which includes a Frequency Synthesizer IC, Voltage-Controlled Oscillator, a pre-scaler, a reference frequency oscillator, and a lowfrequency loop filter. The Frequency Synthesizer IC is a programmable device for setting internal counters for allowing the reference frequency oscillator to be a perfect multiple of the final output frequency. The reference frequency oscillator is a 12.8 MHz TCXO. The low-frequency loop filter is a one-Hertz active type. The 64/128 pre-scaler is used to help aid in the multiplying.

The audio output from the 800-166 COMPRESSOR board is fed into the TRANSMITTER SYNTHESIZER’s VCO which FM modulates the signal at the final output frequency. This modulated RF output signal is then sent to the 800388A Two-Stage RF PA board for final amplification.

Included on the TRANSMITTER SYNTHESIZER board is a high-speed microcontroller. This controller decodes and acts on commands sent from the Front Panel Control & Meter board (800-378A). These commands include new frequency change (direct or channel select), control switch settings, calibration, etc. The controller also monitors and regulates forward power, monitors VSWR and PA temperature, performs auto foldback of power due to high VSWR and then recovers when VSWR lowers, and performs auto shutdown of power due to very high temp. It has internal EEPROM for storing important information such as frequency channels and historical info. The controller also detects synthesizer lock and unlock as well as enabling a fastlock feature for far frequency changes.

FRONT PANEL CONTROL & METER Board, 800-389A (800-382A – some models) – SRPT-30 only

This board does the following:

- Sends F1/F2 state to TRANSMITTER SYNTHESIZER,

- Displays LED alarm information received from the TRANSMITTER SYNTHESIZER,

- Receives and decodes digital data from TRANSMITTER SYNTHESIZER for forward and reverse power

readings and converts to analog signals,

- Directs POWER ADJUST analog signal to TRANSMITTER SYNTHESIZER,

- Multiplexes all analog metering signals via METER SELECT knob for independently monitoring on METER,

- Sends state of the TRANSMIT/STANDBY switch.

FRONT PANEL CONTROL & METER Board, 800-385A (800-378A – some models) – SRPT-40A only

This board does the following:

- Collects and sends commands from the front panel pushwheel switches to the on-board microcontroller of the

TRANSMITTER SYNTHESIZER board,

- Displays LED alarm information received from the TRANSMITTER SYNTHESIZER,

- Receives and decodes digital data from TRANSMITTER SYNTHESIZER for forward and reverse power

readings and converts to analog signals,

- Directs POWER ADJUST analog signal to TRANSMITTER SYNTHESIZER,

- Multiplexes all analog metering signals via METER SELECT knob for independently monitoring on METER,

- Sends state of the TRANSMIT/STANDBY switch.

TWO-STAGE RF POWER AMPLIFIER Board, 800-388A (800-373A – some models)

The RF output signal (50 mW max) from the TRANSMITTER SYNTHESIZER is fed into this TWO-STAGE RF POWER AMPLIFIER board. The RF goes through two stages of RF amplification. The first stage (U2) is a 1-Watt (max) pre-driver. It has an input and output transformer (T1 and T2) for achieving optimum 50 Ohm matching between the stages. 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. An Automatic Power Control (APC) circuit residing on the TRANSMITTER SYNTHESIZER board stabilizes and maintains an accurate output power level by comparing it to a reference power level which is set by the user via the front panel POWER ADJUST pot. The APC circuit samples the forward power via the coupled forward power on PA board.

This board also provides regulated B+ for powering the PA and the rest of the chassis when using 15-30 Volts external supply. Finally, there also exist circuitry for regulating the fan, measuring PA temperature, and monitoring PA current.

SWITCHING POWER SUPPLY, 800-383A (800-324A – some models)

The Switching Power Supply accepts input from 110-120 or 220-240 VAC and supplies 15 VDC and up to 10 Amperes to power the SRPT-30/40A. The power supply must be switched to the appropriate 115 or 230 position. This is usually done at the factory.

RPU TRANSMITTER I/O Board, 800-379AR

This board passes and distributes external power supply input via the back-panel ACCESSORY connector. It also passes and directs the ENCODE, TX REM CNTL, and external audio signals. All signals are LC filtered.

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.

N is made up by the internal n and a counters of the Frequency Synthesizer IC and by P, the divide-by-128 prescaler. The value N is equal to: N=n x P + a. We can now write Fout in the form: Fout = Fr x (n x P + a).

Therefore, with P as a constant value of 128, the n and a counters can be programmed in such a way that the output frequency Fout will always be an integer multiple of the Reference Frequency, Fr. The a-counter will always be a number from 0 to 128, and the n-counter will be a number from 1 to 1023.

The Reference Frequency, Fr, is generated by the 12.8 MHz TCXO (Temperature Controlled Crystal Oscillator) and the internal R-counter of the Frequency Synthesizer IC. This relation is simply: Fr = Fosc / R, where Fosc = 12.8 MHz and R is the programmable R-counter.

The desired output frequency and the Reference Frequency information is sent from the operator via the front panel to the microcontroller. The microcontroller will set the n and a-counters to yield the requested output frequency, and will set the R-counter to yield the requested Reference Frequency. The Reference Frequency is rarely changed, so typically, Fref is treated as a constant and only the output frequency is changed.

The output frequency is modulated by the injected audio at the input of the VCO. The amount of modulation is determined by the Modulation setting. The VCO will alter the output frequency in deviation and rate corresponding to the amplitude and rate (frequency) of the input voltage signal (audio). This is commonly known as frequency modulation (FM). Since the loop filter has a low frequency response (1 Hz), the PLL will not track the modulated signal and as a result, only the VCO output will change.

The RF power and power control circuit is shared by the TRANSMITTER SYNTHESIZER and the TWO-STAGE RF POWER AMPLIFIER. The output of the VCO is sent to a controlled amplifier and is then sent to the TWO-STAGE RF POWER AMPLIFIER for final amplification. To maintain a steady and constant RF output (over temperature and voltage changes), a sample of the RF output power (Forward coupling) is sent to the Automatic Power Control (APC) circuit and compared to a reference output power setting. Any delta changes are instantly compensated for in the APC circuit and an adjustment is made in the controlled amplifier. A MAX POWER setting can be user adjusted to limit the final RF output power.

The low-pass filter (LPF) following the final amplifier will filter out all spurious harmonics to a level lower than – 60 dB. The Reverse coupling samples any return power and is sent to the microcontroller. Since the Forward coupling is also sent to the microcontroller, the VSWR can be determined. The microcontroller will “foldback” the output power if the VSWR exceeds a value of 4. Finally, all front panel alarms and indicators are sent from the microcontroller.

Forward Power Calibration – SRPT-40A Only

Note: The SRPT-30 Forward Power Calibration can only be performed at the factory.

CAUTION

THIS ADJUSTMENT HAS BEEN SET AT THE FACTORY AND SHOULD NOT REQUIRE ANY

FURTHER ADJUSTMENTS.

WARNING

TO MAINTAIN CALIBRATION, NEVER ADJUST THE FP CAL (R20) POT ON THE TWO-STAGE RF

PA BOARD, OTHERWISE THE FORWARD POWER MUST BE RECALIBRATED.

IF IT BECOMES NECESSARY TO RECALIBRATE, READ AND STUDY THIS SECTION

CAREFULLY BEFORE PROCEEDING.

1. Power down the SRPT-40A (i.e., turn off AC LINE switch or turn off external supply).

2. Make sure that the WATT METER is connected to the ANTENNA connector and that the WATT METER is

terminated with a 50-Ohm load rated at 100 Watts minimum.

3. Remove cover from SYNTHESIZER.

4. On the SYNTHESIZER make sure that the P2 jumper is in the FP position (FP is the normal position).

5. On the TWO-STAGE POWER AMPLIFIER board, tweak the FP CAL pot (R20) fully clockwise (approximately

20 turns).

6. On the SYNTHESIZER, tweak the MAX PWR pot (R74) fully counter-clockwise (approximately 20 turns).

7. Power up SRPT-40A, but leave front panel TRANSMIT/STANDBY switch in the “STANDBY” position. Wait for

SRPT-40A to become locked on frequency.

8. Referring to Table (2) – Forward and Reverse Power Calibration, find the row that lists your model. Follow this

row to the CAL FREQUENCY column. This number represents the frequency your model is to be calibrated at.

Change the SRPT-40A to this calibrated frequency.

9. Measure the B+ voltage. Adjust the B+ if necessary by referring to Switching Power Supply Adjustment or B+

Adjustment When Using 15-30VDC External Supply. If using a 12-15 volt external supply, adjust its voltage to

12 to 15 volts. It is recommended that the VOLT METER is monitoring B+ throughout this procedure.
