The operation manual for the SCC-1 VHF Crystal Calibrator provides detailed instructions on setting up and operating the device, which includes connecting the SCC-1 to converters and a power source, and using it to obtain calibration points on various amateur bands. It also offers troubleshooting guidance, such as adjusting the frequency by beating against WWV and ensuring proper connections for optimal performance.
Manual Overview
The Drake SCC-1 VHF Crystal Calibrator is a solid-state device used for providing 50 KHz calibration points across HF amateur bands, as well as on 6 meters, 2 meters, and 432 MHz. It operates using a TIS34 field-effect transistor as a 100 KHz oscillator, with signal processing through a 2N3394 trigger transistor and Fairchild 923 and 914 integrated circuits for frequency division and signal shaping. The calibrator requires a 14 to 18 volt DC power supply, typically provided by the Drake Model CPS-1, which also powers SC-2 or SC-6 converters. For operation, connect the SCC-1 to the desired converter using a short, shielded cable. Calibration adjustments can be made through a clearance hole to align with WWV frequencies. Troubleshooting involves ensuring proper connections and power supply, with the schematic diagram available for detailed board-level guidance. Error diagnostics focus on verifying signal output and connection integrity. Calibration adjustments are facilitated by a capacitor accessible via the device cover.
Quick Issues Covered

Installation / Setup
The SCC-1 VHF Crystal Calibrator requires a positive 14 to 18 volt DC source, consuming about 40 mA. It is designed to work with the Drake Model CPS-1, which supplies the necessary voltage. To set up, plug either the SC-2 or SC-6 converters into one side of the SCC-1, and connect the CPS-1 to the other side. Use a shielded low capacity cable to connect the desired output of the SCC-1 to the CAL input connector of the converter, keeping the cable as short as possible. For HF calibration, connect the SCC-1 output to the receiver antenna through a 5 pf disc capacitor. A clearance hole on the SCC-1 allows for frequency adjustment against WWV.
Operation
The SCC-1 operates from a positive 14 to 18 volt DC source at about 40 mA. To connect the SCC-1, plug either the SC-2 or SC-6 converters into one side of the SCC-1, and plug the CPS-1 into the other side. Power from the CPS-1 powers both the SCC-1 and the converter. Connect a shielded low capacity cable from the desired output of the SCC-1 to the CAL input connector of the converter being used. The cable should be as short as possible. Turn the OFF-ON switch to ON to obtain 100 and 50 KHz calibration points. It is possible to connect all the converter outputs to the desired converters at the same time. If the SCC-1 is to be used as an HF calibrator only, connect the output of the SCC-1 to the receiver antenna through a 5 pf disc capacitor. A console is available that will accept the SCC-1, CPS-1, SC-6, SC-2, and one other converter. This is the Drake Model CC-1. Switching between converters and HF is provided by one knob, and calibrator OFF-ON is provided from the front panel. A clearance hole is provided in the end of the SCC-1 cover so that C-1 can be adjusted to the exact frequency by beating against WWV. The frequency is factory adjusted but can be checked against WWV.
