The Drake MANUAL covers the installation, alignment, and operation of the NB5 Noise Blanker in the TR5, detailing steps such as removing interconnecting cables, installing the NB5 board, and aligning components for optimal performance. It also provides troubleshooting information by explaining the theory of operation, including how the noise blanker processes signals and noise pulses to maintain effective blanking action.
Manual Overview
The service manual for the Drake NB5 Noise Blanker Model 1558 provides detailed instructions for installation, alignment, and operation within the TR5 radio system. Installation involves removing interconnecting cables and the cabinet wraparound, followed by replacing the IF Switching board with the NB5 board. Proper connection of coax and wire connectors is crucial, adhering to color codes and orientations. Once installed, the NB5 is activated by pressing the front panel button labeled NB. The alignment process requires a high impedance VTVM and a signal generator set to 14.250 MHz. The procedure involves tuning specific coils and transistors to achieve maximum S-meter and DC voltage readings. The manual emphasizes that the NB5 is factory aligned, and realignment should only be performed if necessary. The theory of operation explains how the noise blanker processes the 5.645 MHz receive signal, using filters and amplifiers to manage noise pulses, ensuring effective blanking without degrading signal quality.
Quick Issues Covered
- Diagnose NB5 installation issues on Drake TR5 model.
- Troubleshoot NB5 alignment using VTVM and signal generator.
- Refer to schematics for NB5 circuit tracing and component identification.

Installation / Setup
The installation of the NB5 Noise Blanker in the TR5 involves several steps. First, all interconnecting cables from the TR5 must be removed. The cabinet wraparound is then removed by taking out eight screws on the bottom and sliding it toward the rear. The IF Switching board is removed by unscrewing two screws and washers, unplugging three 2-pin coax connectors and one 4-pin wire connector, and then removing the board. The NB5 board is installed by sliding it into the radio, securing it with screws and washers, and connecting the coax and wire connectors, ensuring proper orientation and color code sequence. The cabinet wraparound is reinstalled with eight screws, and the TR5 is reconnected to other station equipment. The NB5 operates when the front panel button labeled NB is depressed.
