Introduction This manual provides technical information necessary

for servicing the Yaesu VR-500 Communications Receiv­er. Information on its installation and operation can be found in the VR-500 Operating Manual, which is provid­

ed with the receiver, and Accessory information may be found in the documents accompanying the optional equip­ment.

The VR-500 is a high-performance miniature commu­nications receiver providing general coverage reception from 100kHz to 1300 MHz on the CW, SSB (LSB and USB), AM, and FM (Wide and Narrow bandwidths) modes (this coverage includes the AM and FM broadcast bands, HF Short-wave Bands up to 16 MHz, VHF and UHF TV bands, the VHF AM aircraft band, and a wide range of commer­cial and public safety frequencies!) .

Servicing this equipment requires expertise in handling

surface mount chip components. Attempts by unqualified persons to service this equipment may result in perma­nent damage not covered by warranty. For the major cir­cuit boards, each side of the board is identified by the type of the majority of components installed on that side.

The VR-500 circuitry includes three modules: (1) the RF Unit, (2) the CNTL Unit, and (3) the AF Unit.

The RF Unit is a module consisting of the front-end unit, 1st IF amplifier, 2nd IF amplifier, PLL circuit, and power supply. The AF Unit consists of the 3rd IF amplifier, de­tector circuit, audio amplifier, and power supply. The CNTL unit includes the CPU, LCD, LCD driver, and EE­PROM.

RF Unit Incoming RF signal from the antenna jack is fed through the A TT circuit to a diode switch, then to one of the nine band-pass filters and RF amplifiers selected by the receive

frequency data from the microprocessor.

The amplified RF signal is delivered to the 1st IF mixer Q528 (J.1PC2757T) along with the 1st local signal from the PLL circuit, which prod uces the 248.45 MHz or 429.15 MHz 1st IF signal.

The 248.45 MHz 1st IF signal is fed through the roofing filter, F502 (LSF819-248-220KO), to the 1st IF amplifier Q532 (2SC5006). In the case of the 429.15 MHz 1st IF, the signal is fed through filter F501 (LSFB19-429-800KO) to IF amplifier Q530 (2SC5006).

The filtered and amplified 1st IF signal is delivered to the 2nd IF mixer Q534 (3SK318) along with the 2nd local sig­nal from the PLL circuit, which produces the 10.7 MHz

2nd IF signal. The 10.7 MHz 2nd IF signal is fed through ceramic filter F503 (SFECV10.7MA5-Z) and 2nd IF am­plifier Q535 (2SC4215Y) to the IF subsys tem IC Q302 (TA31136FN) on the AF Unit, which contains the 3rd IF

mixer, 3rd local signal oscillator, and FM detector.

The 1st local VCO Q705 (2SC5010) and Q711 (2SC5006) oscillates between 371.55 and 880.90 MHz according to the programmed receiving frequency. The 1st local signal is fed through buffer amplifiers Q702 and Q709 (both J.IPA811T) to the 1st IF mixer Q528. The 2nd local VCO Q537 (2SC5006) oscillates at 237.75

MHz or 259.15 MHz, according to the programmed re­ceivin g frequency. The 2nd local signal is fed through

Circuit Description buffer amplifier Q536 (2SC5006) to the 2nd IF mixer Q534.

PLL IC Q541 (M815F02PFV) consists of a data shift reg­ister, reference frequency divider, phase comparator, and charge pump. Serial PLL data from the microprocessor is converted into parallel data by the shift register in the PLL IC and latched into the comparative frequency divider and reference frequency divider to set a frequency dividing ratio for each. A 15.2 MHz reference signal produced by X501 and Q542 (2SC4617) is delivered to the PLL IC. The

internal reference frequency divider divides the 15.2 MHz reference by 3040 (or 2432) to obtain a reference frequen­cy of 5kHz (or 6.25 kHz), which is applied to the phase compara tor for the 1st local PLL loop. Meanwhile, the in­ternal reference frequency divider divides the 15.2 MHz reference by 1520 (or 1216) to obtain a reference frequen­cy of 10kHz (or 12.5 kHz), which is applied to the phase comparator for the 2nd local PLL loop.

AF Unit The 10.7 MHz 2nd IF signal from the RF Unit is delivered to the 3rd IF mixer section in the IF subsystem IC Q302 along with the reference signal generated by 10.245 MHz crystal X301, which results in the 455kHz 3rd IF signal.

If the signal is a (455 kHz) NFM s ignal, it is fed through ceramic filter F302 (KBF-455RS-15A), to strip away any unwanted mixer products, and is then applied to the dis­

criminator in the IF subsystemIC Q302, which produces the demodulated audio.

In the case of a 455kHz WFM signal, it is applied directly to the discriminator in the IF subsystem IC Q302, which produce the demodulated audio.

For AM signals, the IF energy is fed through ceramic filter F302 (KBF-455RS-15A), and is then applied to the 3rd IF amplifier Q343, Q31 1 and Q314 (all 2SC4617R). The am­plified 455kHz AM signal is delivered to the AM detec­tor Q315 (MA729), which produces the demodulated au­dio.

SSB/ CW signals are fed through ceramic filter F301 (KBF-455RS-4AS), then applied to the 3rd IF amplifier Q343, Q311 and Q314 (all 2SC4617R). The amplified 455kHz

SSB/ CW signal is delivered to the ring demodulator Q319 and Q320 (both MA729) along with the 456.5 kHz (LSB/ CW) or 453.5 kHz (USB) BFO local, generated by ceramic oscillator X302 and Q317 (2SC4617R), thus producing the demodulated audio.

The demodulated audio is fed through analog switch Q323 (8U40948CFV) to the audio pre-amplifier Q333 (UMX2N).

Circuit Description The amplified audio signal is fed through audio volume potentiometer RISI on the CNTL Unit to the AF amplifier Q336 (2SA1588Y), and the amplified audio signal is ulti­mately fed through the EAR jack to the internal speaker or an external earphone.

Required Test Equipment The following test equipment (and thorough familiarity with its correct use) is necessary for complete realignment. Correction of problems caused by misalignment result­ing from use of improper test equipment is not covered under the warranty policy. While most steps do notre­

quire all of the equipment listed, the interactions of some adjustments may require that more complex adjustments

be performed afterwards. Do not attempt to perform only a single step unless it is clearly isolated electrically from all other steps. Have all test equipment ready before be­ginning, and follow all of the steps in a section in the or­

der presented.

1. RF Signal Generator with calibrated output level at 1300 MHz

2. Deviation Meter (linear detector) 3. AF Millivoltmeter 4. SINAD Meter 5. Regulated DC Power Supply adjustable from 3 to 15

DC, 1A 6. Frequency Counter: >0.1 ppm accuracy at 1300 MHz

7. AF Signal Generator 8. DC Voltmeter: high impedance 9. DC Ammeter 10. 8 n AF Dummy Load

11. Spectrum Analyzer

Alignment Preparation & Precautions Correct alignment requires that the ambient temperature

be the same as that of the receiver and test equipment, and that this temperature be held constant between 20°

and 30° C (68°- 86° F). When the receiver is brought into the shop from hot or cold air it should be allowed some time for thermal equalization with the environment be­fore alignment. If possible, alignments should be made

with oscillator shields and circuit boards firmly affixed in place. Also, the test equipment must be thoroughly warmed up before beginning.

Note: Signa/levels in dB referred to in this procedure are based on 0 dB11 = 0.5 ftV( closed circuit).

Alignment Test Setup Set up the test equipment as shown below for receiver alignment.
