4、 Field Coil Voltage Drop 6 volts Antenna Circuit The antenna circuit is designed to work with an -antenna having a total capacity including the shielded lead-in not to exceed 150 mmf. If an antenna having a larger capacity is to be used, it will b necessary to add a capacitor in series with the lead

5、 from antenna filter L-1 to the antenna coil terminal (A). Where a Double Under the Running Board .type of antenna is to be used having a capacity of approximately 200 mmf. the capacitor added should be approximately 300 mmf. The insulated running board type having an approxi- mate capacity of 550 m

6、mf. will require a capacitor of approxi- mately 200 mmf. Cars using an insulated steel top of ap- proximately 3,500 mmf. will require a series capacitor of 150 mmf. After installation, and with antenna connected, tune in a weak station near 1,400 kc and adjust compensator trimmer (C-3) for maximum s

7、ignal output. This trimmer is accessible by prying off the nameplate between the control knobs. Antenna Filter A filter is included in the antenna circuit. Being completely shielded, it prevents radiating ignition interference within the set. It also reduces the possibility of picking up vibrator in

8、terference. The filter unit is mounted inside a steel shell which in turn is welded to the chassis. The shielded antenna lead-in makes contact with the filter unit within the steel shell and is held in place by a bayonet type connector.

The position of the sector gear on the rocker plate shaft should be adjusted so that there is clearance between the rocker -plates and the frame of the push-button mechanism at both extremities of gang rotation. Thus correct adjustment prevents the rotation of the gang being limited by

24、 the rocker plates touching the frame. 3. The drive cord should have 81/2 turns around the tun- ing shaft as shown in the illustration.
