The Drake TUM714 manual provides instructions for setting up the up-converter in a rack mount configuration, connecting it to power and input sources, and ensuring proper operation with compatible equipment. It also includes troubleshooting guidance, specifications, and warranty information to assist users in maintaining and repairing the device as needed.
Manual Overview
The Drake TUM714 T Channel Up-Converter manual provides detailed guidance on installation, operation, and troubleshooting. The unit is designed for use in a 19-inch rack and is compatible with both 12 and 4 position rack mounting frames. It up-converts “T” channel signals from 5 to 54 MHz to outputs 168.25 MHz higher, suitable for NTSC video and audio or digital signals like QPSK and QAM. For troubleshooting, the manual emphasizes checking the power indicator on the front panel, which should be lit when connected to a DC power source. If issues arise, users should verify connections at the RF input and output connectors, ensuring proper signal flow. Calibration involves ensuring input levels do not exceed +30 dBmV to prevent distortion. The manual does not specify error codes but highlights the importance of correct maintenance and repair, noting that improper handling can void the warranty. For board-level issues, contacting R.L. Drake Company or an authorized service facility is advised.
Quick Issues Covered
- Diagnose power-up failures via front panel power indicator light.
- Calibrate input frequency range from 5 MHz to 54 MHz.
- Check error codes via RF input/output connections for signal issues.
Overview
The R.L. Drake model TUM714 is a “T” channel block up-converter designed for use in a 19” wide rack, compatible with Drake’s 12 position and 4 position rack mounting frames. It accepts inputs in the “T” channel range of 5 through 54 MHz and up-converts them to an output 168.25 MHz higher in frequency. The TUM714 is typically used with a demodulator to derive NTSC video and audio from a “T” channel signal and can handle a maximum input signal level of +30 dBmV without significant distortion. It has approximately unity gain and can translate digital QPSK, QAM, or USB signals as well as analog NTSC signals.

Controls & Indicators
The front-panel control/indicator present is the POWER Indicator, which lights up when the unit is connected to the required source of DC power via the rear panel DC INPUT connector.
Installation / Setup
Mount the TUM714 in the 12 position rack frame. Connect a power cable from the power supply to the power connector on the TUM714. Connect the “T” channel input as indicated. Connect the output from the TUM714 to the demodulator input or to other desired equipment. The RF input accepts inputs from 5 to 54 MHz, and the RF output connects to a demodulator. The DC input connector is a 3-pin male connector that requires the appropriate mating DC power cable with proper orientation and wiring.
