User manual YAESU VX-10

[. . . ] Two PCB layout diagrams are provided for each double-sided board in this transceiver. Each side of the board is referred to by the type of the majority of components installed on that side ("Side A" or "Side B"). In most cases one side has only chip components (surface-mount devices), and the other has either a mixture of both chip and leaded components (trimmers, coils, electrolytic capacitors, ICs, etc. ), or leaded components only. While we believe the information in this manual to be correct, VERTEX STANDARD assumes no liability for damage that may occur as a result of typographical or other errors that may be present. [. . . ] Also, Vertex Standard 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. Required Test Equipment 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. RF Signal Generator with calibrated output level at 200 MHz Deviation Meter (linear detector) In-line Wattmeter with 5% accuracy at 200 MHz 50-Ohm 10-W RF Dummy Load 8-Ohm AF Dummy Load Regulated DC Power Supply adjustable from 6 to 15 VDC, 2A Frequency Counter: 0. 2-ppm accuracy at 200 MHz AF Signal Generator AC Voltmeter DC Voltmeter: high impedance VHF Sampling Coupler SINAD Meter Alignment Preparation & Precautions A 50-Ohm 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. Inject a 146. 050 MHz signal at a level of ­12 dBµV (with 1 kHz modulation @±3. 5 kHz deviation) from the RF signal generator. Press the [F/W] key, then press the [MR(SKIP)] key to set the alignment parameter to "A7 SQL U/D. " 4. With in five second of appearing the "A7 SQL U/D" on the display, press the [ (MHz)] key. Increase the RF signal generator output level to ­3 dBµV. Press the [F/W] key to recall the alignment parameter to "A7 SQL U/D. " 7. With in five second of appearing the "A7 SQL U/D" on the display, press the [ (MHz)] key. S-meter Sensitivity 1. Inject a 146. 050 MHz signal at a level of ­5 dBµV (with 1 kHz modulation @±3. 5 kHz deviation) from the RF signal generator. Press the [F/W] key, then press the [MR(SKIP)] key to set the alignment parameter to "A6 SM U/D. " 4. With in five second of appearing the "A6 SM U/D" on the display, press the [ (MHz)] key. Increase the RF signal generator output level to +23 dBµV. Press the [F/W] key to recall the alignment parameter to "A6 SM U/D. " 7.
