1. SAFETY Before applying power IMPORTANT! U.S.A. and Canada Units shipped to the U.S.A. and Canada are designed for operation on 120 volts AC only. These units are not equipped with an AC voltage selector switch and the discussion of such a switch that follows should be disregarded.
SAFETY INSTRUCTIONS 1. Read Instructions — All the safety and operating in- structions should be read before the appliance is oper- ated. 2. Retain Instructions — The safety and operating instruc- tions should be retained for future reference.
EXAMPLE OF ANTENNA GROUNDING ACCORDING TO NATIONAL ELECTRICAL CODE INSTRUCTIONS CONTAINED IN ARTICLE 810 –"RADIO AND TELEVISION EQUIPMENT" a Use No. 10 AWG (5.3 mm 2 ) copper. No. 8 AWG (8.4 mm 2 ) alu- C Mount antenna discharge unit as close as possible to where minuet, No.
Touching the power plug when your hands are wet may result in a serious electric shock. Install the unit on a flat, vibration-free rigid table. Never pull, bend or extend the power cord. This could da- mage the power cord, resulting in a broken cord or short- circuit.
Thank you for purchasing the new R-5000 Communications Receiver. Please read this Instruction Manual carefully before placing your receiver in service. This unit has been carefully engineered and manufactured to rigid quality standards, should give you satisfactory and dependable operation for many years.
2. SPECIFICATIONS AND ACCESSORIES 2-1. SPECIFICATIONS Model Specifications R-5000 U.S.A. version Europe, U.K. and other market versions Australia version West Germany version Circuitry AM/USB/LSB/ CW/.
Frequency accuracy Less than ± 10 PPM Frequency stability Less than ± 10 PPM Output EXT. speaker 1.5 W across 8 ohms load (10% distortion) REC jack 300 mV across 4.7 kΏ load (at 1 mV input with 30% mod. in AM or 3 kHz dev. in FM) Output load impedance 8 ohms min.
3. INSTALLATION AND CONNECTION 3-1. INSTALLATION 3-1-1. Bail The receiver can be elevated for operating convenicence. Caution: Do not use the bail to carry the receiver. A. Power supply Cautions: Cautions: 1. The POWER switch must be OFF before you con- 1.
B. Antenna and grounding (A) Antenna Installation of antenna and grounding is important for opti- mum reception of short-wave, broadcast or amateur radio signals. A good outdoor antenna will provide the best re- sults. Caution: Protect your Equipment Use a LIGHTNING ARRES- TOR.
3-2-3. Connecting the R-5000 with a transmitter or transceiver 1. Ground the REMOTE connector pin (pin 7) to mute the R-5000 audio during transmission. REMOTE connector The open-circuit voltage at pin 7 is about +4.8 VDC; the short circuit current is about 0.
4. OPERATION 4-1. CONTROL FUNCTIONS 4-1-1. Front panel Note: All segments on the Display Panel and Indi- cators are shown on for this explanation. C) POWER switch Press to turn the power ON or OFF. Note: When the AC or DC power cable is connected the clock and the timer function even if the POWER switch is turned OFF.
J SELECTIVITY switch When an optional filter is installed, the receiver's passband can be switched to one of four different bandwidths by us- ing the SELECTIVITY switch. The switch has five positions; AUTO, N, M 1, M2 and W, that are used to select the bandwidth.
11 RF gain control This control adjusts the gain of the receiver high- frequency amplifier section. For normal receiver pe rf ormance, and maximum gain, this control should be in the full clockwise position. If you are having trouble copying the desired signal make a note of the stations peak S-meter reading.
When pulsating noise, such as that caused by automobile ignitions is encountered, place the NB 1 switch ON. This switch will not help to eliminate atomospheric or line noises, only pulse type noise. Note: NB 1 is disabled during FM operations. 18 NB level control Controls the noise blanker operating level.
Frequency dis- play : Frequency of the VFO or the Me- mory Channel is displayed. Fre- quency is expressed in 10 Hz steps (100 Hz for VHF band). Timer operation display : When the ON TIME or OFF TIME switch is pressed, the Fre- quency display changes to indi- cate timer operational status dis- play (ON/OFF and time).
4-1-2. Rear panel VHF ANT connector (Optional VC-20 VHF Converter Unit is required.) Installation area for the VHF antenna connector. AC power connector For connection of the supplied AC power cable. 1 AC voltage selector switch (Except U.S.A. version) Refer to the "SAFETY" section on page 2.
4-2. RECEIVE 4-2-1. Microprocessor back-up battery The R-5000 has a rechargeable back-up battery which is charged automatically while the AC power cable is con- nected to an AC outlet. It takes about 6 hours to recharge a deeply discharged battery using the AC power cable.
Note: The desired receive frequency can also be entered dir- ectly by using the Numeric Keypad. For details of this operation please refer to the section 4-2-8"Direct key- board frequency entry". 4-2-6. Frequency step 1. The frequency step is set automatically depending on the mode that has been selected.
4-2-9. CW zero-beat operation 1. When an optional filter is not used, tune the TUNING knob so that the receive beat frequency is approximate- ly 800 Hz. 2. When an optional CW filter is installed the simplest method to use is to adjust the TUNING knob for maxi- mum S-meter deflection.
4-3. MEMORY The R-5000 incorporates a convenient 100 channel me- mory that can be used to store and recall commonly used frequencies. These channels can be subdivided into 10 user-defined groups to tailor the R-5000 for optimum operation in a particular application.
1. During Memory Channel operation, press the VFO/M key to change to select VFO operation. 2. Press the M IN key once to initiate memory Scroll. The M.
4-4. SCAN Both Memory Scan and Program Scan are possible. In the AM and FM modes, scanning stops when the BUSY indi- cator lights. (This is known as Time Operated (about five seconds) Scan.) Time Operated Scan can be changed to Carrier Operated Scan (in which scanning stops when an AM or FM signals is present).
Notes: 1. If you try to perform program scan in a memory group that does not have data in channels 8 and 9 an error tone will sound. 2. No scanning will be performed if Memory Channel 8 and Memory Channel 9 in the selected group are not stored in the HF band or the VHF band.
4-5. CLOCK AND TIMER TIMER switch This switch controls the time operation. When the TIMER switch is ON, the timer has priority over the POWER switch. If the radio will not turn on, check this switch! ® CLOCK1 /OFF/CLOCK2 switch CLOCK 1 : Use this position, to display local time.
B. Time set 1. Select the CLOCK for which the time is to be set. 2. Press the TIME SET switch. 3. Simultaneously press the HOUR and MINUTE keys to stop the clock. The colon on the clock display lights continuously, indi- cating that the clock has stopped and that you can now begin programming.
E. Turning external units ON or OFF You can use the R-5000's TIMER to turn external units such as tape recorders ON or OFF. Various pin connec- tions for timer states are shown below. 5. MAINTENANCE 5-1. GENERAL INFORMATION Your receiver has been factory aligned and tested to speci- fication before shipment.
5-4. IN CASE OF DIFFICULTY The problems described in this table are failures caused in general by improper operation or connection of the re- ceiver, not by defective components. Examine and check according to the following table. If the problem persists, contact an authorized agent or service station.
6. OPTIONAL ACCESSORIES The following accessories are available for more sophisti- cated operation of your receiver. • HS-7 MICRO HEADPHONES (16 OHMS) • HS-6 COMMUNICATIONS HEADPHONES (12.5 OHMS) Deluxe, very light-weight headphones designed for com- munications equipment.
tic music from overseas broadcast stations or transmis- sions from Amateur radio stations and various industrial, marine, government, and military. It is also interesting to collect reception or verification (QSL) cards.
Frequency Distribution in the Broadcast and Amateur Bands. The R-5000 receiver covers from 100 kHz to 30 MHz, to receive international broadcast and communication ser- vices.
• Doublet Antenna This type of antenna is suitable for reception of a specific band. The relation between the overall length "L" and the tuned frequency is: 7-2. ANTENNA AND GROUNDING 7-2-1. Antenna The following describes various antenna types and their installation.
• Yagi Antenna The Yagi antenna is best suited for reception in a specific band. This antenna features excellent directivity; it pro- vides high gain and minimizes interference when properly installed. Yagi antennas commercially available are de- signed only for HAM band reception.
