K6620415X20AMATEUR RADIO WITH SCANNING RECEIVER

March 09, 2010 Federal Communications Commission Authorization and Evaluation Division, 7435 Oakland Mills Road Columbia, MD 21046 USA Re: VX-8GR (FCC ID: K6620415X20) Gentlemen: The scanner receiver equipment meets the requirements of the FCC Rules, 15.121(a). Compliance is achieved through the following methods: The scanner receiver in this equipment is incapable of tuning, or readily being altered, by the User to operate within the frequency bands allocated to the Domestic Public Cellular Telecommunications Service in Part 22. Blocking of the cellular frequencies is implemented in the firmware of the unit’s main control central processing unit (CPU). Coverage of 824 – 849 MHz and 869 – 894 MHz is completely blocked, since it is done in the microprocessor, and cannot be re-enabled by any user-accessible procedure, including diode, resistor, or jumper changes, nor by connection of any external device such as a personal computer, nor by installation of any “special” enabling semiconductor device. Sincerely, Vertex Standard Co., Ltd. Yukimasa Tomita Executive Managing Officer Engineering Division

FCC ID: K6620415X20 IC: 511B-20415X20 VX-8GR Alignment Vertex Standard Co.,Ltd. 1 VX-8GR Alignment Introduction The VX-8GR is carefully aligned at the factory for the specified performance across the amateur band. Realignment should therefore not be necessary except in the event of a component failure. Only an authorized Yaesu representative should perform all component replacement and service, or the warranty policy may be void. The following procedures cover the adjustments that are not normally required once the transceiver has left the factory. However, if damage occurs and some parts subsequently 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 Yaesu service technicians who are experienced with the circuitry and fully equipped for repair and alignment. If a fault is suspected, contact the dealer from whom the transceiver was purchased for instructions regarding repair. Authorized Yaesu 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, Yaesu reserves 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 realignment determined to be absolutely necessary. The following test equipment (and familiarity with its 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. Required Test Equipment • RF Signal Generator with calibrated output level at 1 GHz • Deviation Meter (linear detector) FCC ID: K6620415X20 IC: 511B-20415X20 VX-8GR Alignment Vertex Standard Co.,Ltd. 2 • In-line Wattmeter with 5% accuracy at 500 MHz • 50-ohm, 10-W RF Dummy Load • 8-ohm AF Dummy Load • Regulated DC Power Supply adjustable from 3 to 15 V DC, 3A • Frequency Counter: 0.2-ppm accuracy at 1 GHz • AF Signal Generator • AC Voltmeter • DC Voltmeter: high impedance • UHF Sampling Coupler • SINAD Meter Alignment Preparation & Precautions A 10-W RF load and in-line wattmeter must be connected to the main antenna jack in all procedures that call for transmission, alignment is not possible with an antenna. After completing one step, read the next step to see if the same test equipment is 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 ~ 86 °F (20 ~ 30°C). When the transceiver is brought into the shop from hot or cold air, it should be allowed some time to come to room temperature before alignment. Whenever 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 the alignment procedure are based on 0 dBμ=0.5 μV (closed circuit). Test Setup Set up the test equipment as shown below for transceiver alignment, and apply 8.4 V DC power to the transceiver. Refer to the drawings for Alignment Points. Internal System Alignment Routine This uses a programmed routine in the transceiver which simplifies many previously complex discrete component settings and adjustments with digitally-controlled settings via front panel buttons and LCD indications. To enter the alignment routine: Set the transceiver to the 430 MHz band, then turn the transceiver off. Now, press and hold FCC ID: K6620415X20 IC: 511B-20415X20 VX-8GR Alignment Vertex Standard Co.,Ltd. 3 the [HM/RV] key while powering the radio on again. The display will show the first setting. To exit the alignment routine, press the [HM/RV] key. After performing the system alignment in its entirety, individual settings can be returned to and adjusted should the need arise. PLL Reference Frequency (PLL REF) z Rotate the DIAL knob to select the display “PLL REF”. z Press the [V/M] key to enable adjustment of the PLL Reference Frequency. z Press the PTT switch to transmit the transceiver, rotate the DIAL knob so that the Frequency Counter reading is same frequency of the transceiver’s display (±100 Hz). z Press the [V/M] key to save the new setting A Band Adjustment 430 MHz Band RX Sensitivity (TUNE DC) z Rotate the DIAL knob to select the display “TUNE DC”. z Set the RF Signal Generator to the same frequency of the transceiver’s display, then adjust the RF Signal Generator output level to –10 dBμ (with 1 kHz tone @±3.0 kHz tone). z Press the [V/M] key to enable adjustment of the 430 MHz Band RX Sensitivity. z Rotate the DIAL knob for maximum deflection of the SINAD meter. z Press the [V/M] key to save the new setting 430 MHz Band Squelch Hysteresis (HIS SQL) z Rotate the DIAL knob to select the display “HIS SQL”. z Press the [V/M] key to enable adjustment of the 430 MHz…

Radiation Interference: The test procedure used was ANSI Standard C63.4-2003 using a spectrum analyzer with a pre-selector. The bandwidth of the spectrum analyzer was 100 kHz with an appropriate sweep speed. The analyzer was calibrated in dB above a microvolt at the output of the antenna. The video bandwidth was always greater than or equal to the RBW. Formula Of Conversion Factors: The Field Strength at 3m was established by adding the meter reading of the spectrum analyzer (which is set to read in units of dBμV) to the antenna correction factor supplied by the antenna manufacturer. The antenna correction factors are stated in terms of dB. The gain of the Preselector was accounted for in the Spectrum Analyzer Meter Reading. Example: Freq (MHz) Meter Reading + ACF +CL = FS 33 20 dBμV + 10.36 dB/m +0.40 dB =30.36 dBμV/m @ 3m ANSI C63.4-2003 Section 10.1.7 Measurement Procedures: The unit under test was placed on a table 80 cm high and with dimensions of 1mby 1.5m. The table used for radiated measurements is capable of continuous rotation. When an emission was found, the table was rotated to produce the maximum signal strength. At this point, the antenna was raised and lowered from 1m to 4m. The antenna was placed in both the horizontal and verticals planes. If powerline conducted testing was required for this device, th…
