FCC ID: K6630493X20 IC: 511B-30493X20 Circuit Description 1/2 Vertex Standard Co., Ltd. HX300 Circuit Description 1. Receive Signal Path Incoming RF from the antenna jack is delivered to the RF Unit and passes through a low-pass filter consisting of coils L1001, L1003 and L1006,capacitors C1014, C1016, C1020,C1023,C1029,C1033 and C1042, and antenna switching diode D1005. Signals within the frequency range of the transceiver enter a band-pass filter consisting of coils L1018 and L1020, capacitors C1096, C1098 and C1102, then amplified by Q1023. The amplified RF is then passed through a SAW filter XF1001, the pure in-band input signal is delivered to 1st mixer Q1034. Buffered output from the VCO is amplified by Q1006 to provide a pure first local signal between 134.35 and 141.575 MHz for injection to the first mixer Q1034. The 21.7 MHz first mixer product then passes through monolithic crystal filter XF1002/XF1003 to strip away all but the desired signal, which is then amplified by Q1039. The amplified first IF signal is applied to FM IF subsystem IC Q1041, which contains the second mixer, second local oscillator, limited amplifier, noise amplifier, and RSSI amplifier. A second local signal is produced from the PLL reference/second local oscillator of X1001 (21.25 MHz). The 21.25 MHz reference signal is delivered to mixer section of Q1041 which produce the 450 kHz second IF mixed with the first IF signal. The second IF then passes through the ceramic filter CF1001 to strip away unwanted mixer products, and is then applied to the limited amplifier in Q1041, which removes amplitude variations in the 450kHz IF, before detection of the speech by the ceramic discriminator CD1001. 2. Audio Amplifier The demodulated audio signal from the Q1041 passes through a band-pass filter and High-pass filter, then applied to the de-emphasis of Q1005. Then passes through the audio mute switch Q1036, the Electric Volume audio volume Q1035 and the audio power amplifier Q1043, providing up to 700 mW of audio power to the 8 Ω loudspeaker. 3. Squelch Control The squelch circuitry consists of a noise amplifier and band-pass filter and noise detector within Q1041. When no carrier received, noise at the output of the detector stage in Q1041 is amplified and band-pass filtered by the noise amplifier section of Q1041 and the network between pins 7 and 8, and then rectified by detection circuit in Q1041. The resulting DC squelch control voltage is passed to pin 100 of the microprocessor Q1033. If no carrier is received, this signal causes pin 82 of Q1033 to go low and the Electric Volume audio volume Q1035 is mute. The Electric Volume audio volume Q1035 is disable the supply voltage to the audio amplifier Q1043. Thus, the microprocessor blocks output from the audio amplifier, and silences the receiver, while no signal is being received (and during transmission, as well). 4. Transmit Signal Path The speech input from the microphone MC1001 passes through the audio amplifier Q1003, which is adjusted the microphone gain. The speech signal passes through pre-emphasis circuit to Q1003, which contains the IDC, and low-pass filter. The filtered audio signal is applied to varactor diode D1016, which frequency modulates the VCO Q1013. The modulated signal from the VCO Q1013 is buffered by Q1006. The low-level transmit signal is then passes through the TX switching diode D1028 to the buffer amplifier Q1032, driver amplifier Q1028, then amplified transmit signal is applied to the final amplifier Q1018,1019 up to 5.0 watts output power. The transmit signal then passes through the antenna switch D1005 and is low-pass FCC ID: K6630493X20 IC: 511B-30493X20 Circuit Description 2/2 Vertex Standard Co., Ltd. filtered to suppress harmonic spurious radiation before delivery to the antenna. 4-1 Automatic Transmit Power Control Current from the final amplifier is sampled by C1007 and C1012, and R1005 and R1009, and is rectified by D1002. The resulting DC is fed back through Q1031 to the final amplifier Q1019, for control of the power output. When the microprocessor selects ”High” or “Low” power levels, pin 76 of Q1030 to go low at “High” power selected or pin 76 of Q1030 to go high at “Low” power selected. 5. PLL Frequency Synthesizer The PLL circuitry on the Main Unit consists of VCO Q1012(RX),1013(TX), VCO buffer Q1006, PLL subsystem IC Q1029, which contains a reference divider, serial-to-parallel data latch, programmable divider, phase comparator and charge pump, and crystal X1001 which frequency stability is ±5 ppm @ -20 to +60 °C. While receiving, VCO Q1012 oscillates between 134.35 and 141.575 MHz according to the transceiver version and the programmed receiving frequency. The VCO output is buffered by Q1006 then applied to the prescaler section of Q1029. There the VCO signal is divided, according to a control signal from the data latch section of Q1029, before being sent to the programmable divider section of Q1029. The data latch section of Q1029 also receives serial dividing data from the microprocessor Q1033, which causes the pre-divided VCO signal to be further divided in the programmable divider section, depending upon the desired receive frequency, so as to produce a 25.0 kHz derivative of the current VCO frequency. Meanwhile, the reference divider sections of Q1029 divides the 21.25 MHz crystal reference from the reference oscillator section of Q1029, by 850 to produce the 25.0 kHz loops reference. The 25.0 kHz signal from the programmable divider (derived from the VCO) and that derived from the reference oscillator are applied to the phase detector section of Q1029, which produces a pulsed output with pulse duration depending on the phase difference between the input signals. This pulse train is filtered to DC and returned to the Varactor D1017 and D1018. Changes in the level of the DC voltage applied to the Varactor, affecting the reference in the tank circuit of the VCO according to the phase difference between the signals d…

FCC ID: K6630493X20 IC: 511B-30493X20 Alignment Vertex Standard Co., Ltd. 1 HX300 Alignment The HX300 has been carefully aligned at the factory for the specified performance across the marine band. Realignment should therefore not be necessary except in the event of a component failure. All component replacement and service should be performed only by an authorized Standard Horizon representative, or the warranty policy may be voided. The following procedures cover the sometimes critical and tedious adjustments that are not normally required once the transceiver has left the factory. However, if damage occurs and some parts are replaced, realignment may be required. If a sudden problem occurs during normal operation, it is likely due to component failure; realignment should not be done until after the faulty component has been replaced. We recommend that servicing be performed only by authorized Standard Horizon service technicians who are experienced with the circuitry and fully equipped for repair and alignment. Therefore, if a fault is suspected, contact the dealer from whom the transceiver was purchased for instructions regarding repair. Authorized Standard Horizon service technicians realign all circuits and make complete performance checks to ensure compliance with factory specifications after replacing any faulty components. Those who do undertake any of the following alignments are cautioned to proceed at their own risk. Problems caused by unauthorized attempts at realignment are not covered by the warranty policy. Also, Standard Horizon, a division of Vertex Standard must reserve the right to change circuits and alignment procedures in the interest of improved performance, without notifying owners. Under no circumstances should any alignment be attempted unless the normal function and operation of the transceiver are clearly understood, the cause of the malfunction has been clearly pinpointed and any faulty components replaced, and the need for realignment determined to be absolutely necessary. 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 not require 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 order presented.

Alignment Preparation & Precautions A dummy load and inline wattmeter must be connected to the main antenna jack in all procedures that call for transmission. Correct alignment is not possible with an antenna. After completing one step, read the following step to determine whether the same test equipment will be required. If not, remove the test equipment (except dummy load and wattmeter, if connected) before proceeding. Correct alignment requires that the ambient temperature be the same as that of the transceiver and test equipment, and that this temperature be held constant between 68 °F and 86 °F (20 °C and 30 °C). When the transceiver 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: Signal levels in dB referred to in this procedure are based on 0 dBμ = 0.5 μV (closed circuit).

Alignment Preparation & Precautions A dummy load and inline wattmeter must be connected to the main antenna jack in all procedures that call for transmission. Correct alignment is not possible with an antenna. After completing one step, read the following step to determine whether the same test equipment will be required. If not, remove the test equipment (except dummy load and wattmeter, if connected) before proceeding. Correct alignment requires that the ambient temperature be the same as that of the transceiver and test equipment, and that this temperature be held constant between 68 °F and 86 °F (20 °C and 30 °C). When the transceiver 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: Signal levels in dB referred to in this procedure are based on 0 dBμ = 0.5 μV (closed circuit). FCC ID: K6630493X20 IC: 511B-30493X20 …
