A. 收音机爱 好者资料库 RadioFans.CN PAGE 362-C QI6, QI6E Alignment Procedure Cathode -Ray Alignment is the preferable method. Connections for the oscillograph are
12、 shown in the chassis drawing. Output Meter Alignment. -If this method is used, connect the meter across the voice coil, and turn the receiver volume control to maximum. Test -Oscillator. -For all alignment operations, connect the low side of the test -oscillator to the receiver chassis, and keep th
13、e output as low as possible to avoid a -v -c action. Calibration Scale on Indicator -Drive -Cord Drum. -The tuning dial is fastened in the cabinet and cannot be used for reference during align- ment., therefore a calibration scale is attached to the indicator -drive - cord drum which is mounted on t
14、he shaft of the gang condenser. The setting of the gang condenser is read on this scale, which is calibrated in degrees. The correct setting of the gang in degrees, for each align- ment frequency, is given in the alignment table. As the first step in r -f alignment, check the ccisition of the drum.
15、The 180 mark on the drum scale must be vetical, and directly over the center of the gang -condenser shaft when die plates are fully meshed. The drum is held to the shaft by means. of two set screws, which must be tightened securely when the drum is in the correct position. To determine the correspon
16、ding frequency for any setting of the calibration scales, , r to the accompanying drawing which shows the dial with 0-180 calibration scales drawn at top and bottom. Pointer for Calibration Scale. -Improvise a pointer for the calibra- tion scale by fastening a piece of wire to the gang -condenser fr
17、ame, and bend the wire so that it points to the 180 mark on the calibra- tion scale when the plates are fully meshed. Dial -Indicator Adjustment. - After fastening the chassis in the cabinet, attach the dial indicator to the drive cable with indicator at the 540 kc mark, and gang condenser fully mes
18、hed. The indicator has a spring clip for attachment to the cable. Spread-BandAlignment.-The most satisfactory method of aligning or checking the spread -baud ranges is on actual reception of short- wave stations of known frequency, by adjusting the magnetite -core oscillator coil for each band so th
19、at these stations come in at the correct points on the dial. In exceptional cases, when the set is being serviced in a location where the noise level is high enough to preventireception of short-wave stations, a test -oscillator may he used for alignment, hut an extremely high degree of accuracy is
20、required in the frequency settings of the test -oscillator, as a slight error will produce considerable inaccuracy on the spread -band dials. The frequency settings of the test -oscillator may be checked by one or both of the following methods: I. Determine the exact dial settings of the test -oscil
21、lator (for fre- quencies at or close to the specified alignment frequencies) by zero -beating the test -oscillator against short-wave stations of known frequency. 2. Use harmonics of the standard -broadcast range of a test -oscil- lator, first checking the frequency settings on this range by means o
22、f a crystal calibrator (RCA Stock No. 9572), or by zero -beating against standard broadcast stations. When a test oscillator is employed for spread -band alignment, a final check should be made on actual reception of short-wave stations of known frequency, and the magnetite -core oscillator coil for
23、 each band should be re -adjusted so that the stations come in at the correct points on the dial. 1 .DET 05C. C11-oSC. 9 MC OC3-ANT. C14OSCg fr/115.2 / 1 V ! 1 LIO-05C. L11-O5C. ytQ-OSC 9.5 MC.
