GENERAL
 |
The SCC-4, 100 kc, crystal calibrator is an oscillator that injects into the receiver a harmonic every 100 kc throughout the receiver's range. |
|
Install the SCC-4 by inserting it into the sock market CALIBRATOR which is located at the rear of the receiver chassis. The calibrator is switched on by placing the front panel switch in the "CAL" position. |
ALIGNMENT
|
The SCC-4 is factory aligned, but due to shock and vibration during shipment, additional adjustment is sometimes necessary. Turn on the receiver. Tune WWW. Make sure that the switch is in the "CAL" position and carefully adjust the trimmer capacitor located on top of the calibrator chassis to zero beat. This completes necessary alignment. |
