2-AC CRYSTAL CALIBRATOR INSTRUCTIONS
 | The 100 KC crystal calibrator is an oscillator so designed that it will inject into the receiver a harmonic every 100 KC throughout the receiver’s range. This corresponds to the numbered dial divisions on your dial. To use your 100 KC calibrator, insert it into the socket marked "CAL." which is located at the rear of the receiver chassis. The calibrator is switched on and off by a front panel switch, marked "CAL." To set the receiver dial accurately, turn the switch to "CAL.", and tune in the 100 KC harmonic nearest the desired operating frequency to zero beat, Then slide the dial glass until the pointer lines up exactly with the
corresponding dial division. |
ALIGNMENT
| All 2-AC’s are factory aligned, but due to shock and vibration during shipment, additional adjustment is sometimes necessary, To do so, turn on receiver with calibrator on and allow it to warm up for at least thirty minutes, Tune in WWV. Make sure that the switch is in the "CAL," position and carefully adjust the trimmer capacitor located on top of the alibrator chassis to zero beat. This completes all necessary alignment. |
