2、ck No. 31031. Allow at least five minutes warm up period before making adjustments. In the event that the receiver is to be used with an external an tenna use one or two feet of wire (as an antenna) to ensure sharp peaking during the final adjustment procedure. For loop operation, the link should be

3、 strapped across terminals on back of set. In either case the procedure is as follows: 1. Make a list of the desired stations, arranged in order from low to high frequencies. 2. Turn the range selector to “A” band, and manually tune in the first station on the list. 3. Turn range selector to “PB” po

4、sition, push in station button No. 1 (extreme left). Then adjust the No. 1 oscillator core (L-14) to receive the station. Adjustment 4. After oscillator core is set correctly, adjust C-8 for maximum output. Clockwise adjustment of cores and trimmers tunes the circuits to lower frequencies. 5. Adjust

5、 for each of the remaining stations in the same manner. 6. Make a final careful adjustment of the oscillator cores and an tenna trimmers. Owing to the telatively high r-f gain, it may be found that a given station can be tuned m at several different settings of the magnetite-core oscillator push-but

6、ton coils. In such cases, it is advisable to unscrew the loop push-button trimmers to minimum capa city before adjusting the magnetite cores. On the 880 to 1,550 kc push-button, the higher frequency stations may be received with L-9 either in or out (oscillator frequency either 455 kc below or 455 k

7、c above the station frequency). The adjust ment with this core in its out position (oscillator frequency 455 kc above the station frequency) is the correct one. Cathode-Ray Alignment is the preferable method. Connections for the oscillograph are shown in the schematic diagram. Output Meter Alignment

8、.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 the output as low as possible to avoid a-v-c action. Electron

9、ic Voltmeter.The electronic voltmeter in the Chanalyst or Volt Ohmyst provides an unexcelled output indicator. It should be connected to the AYC bus, and the test-oscillator output adjusted to produce several volts of AVC. Calibration for Alignment.The dial calibration for alignment pur poses can be

10、 set up in two ways: 1. The dial may be removed from the cabinet by sliding out the two spring pieces which clamp it in its mounting position. The condenser plates should then be turned into full mesh, ths pointer adjusted to the scratch at the left end of the dial back ing plate, and the dial place

11、d on the frame so that its extreme left calibration mark coincides with the pointer The dial may be held in place with scotch tape. In this manner the actual receiver dial is used for alignment. When alignment is finished, the scale should be replaced including the fibre light shields which are fold

12、ed under the ends of the glass scale. 2. A calibration scale is attached to the tuning drum. The correct setting of the gang, in degrees, for each alignment frequency is given in the alignment table. Check the position of the drum, making sure that the 0 degree scale mark is horizontal with the gang

13、 in full mesh. Pointer for Calibration Scale. If method (2) is used, improvise a pointer for the calibration scale by fastening a piece of wire to the chassis, and bend the wire so that it points to the 0 degree mark on the calibration scale when the plates are fully meshed.

27、. Then adjust the No. 1 oscillator core (L-14) to receive the station. Failure to Oscillate on Push -Button Tuning: Should a case of non -oscillation on any push- button range be experienced, check the oscil- lator grid leak to assure that it is 56,000 ohms. Some sets employed a 33,000 ohm leak whic

28、h was occasionally found troublesome with low line voltage. tow -Frequency Oscillator Push -Button Coil: To ensure low -frequency coverage on the push-button oscillator coils in these models, a high -inductance coil, Stock No. 37133, is used for the 540-1,030 kc push-button oscillator ranges. 4. Aft

29、er oscillator core is set correctly, adjust C-8 for maximum output. Clockwise adjustment of cores and trimmer tunes the circuits to lower frequencies. 5. Adjust for each of the remaining stations in the same manner. 6. Make a final careful adjustment of the oscillator cores and an tenna trimmers. Ow

30、ing to the relatively high r -f gain, it may be found that a given station can be tuned in at several different settings of the magnetite -core oscillator push-button coils.
