The manual provides detailed instructions for installing the Electric Clock Timer Kit #38896-2 into the Hammarlund HQ-110 communications receiver, converting it to an HQ-110-C model. It includes guidance on the necessary tools, step-by-step installation, soldering connections, and final setup, while also noting that the clock switch will not automatically turn off the receiver.
Manual Overview
The Hammarlund HQ-110 communications receiver can be upgraded with the Electric Clock Timer Kit #38896-2, transforming it into an HQ-110-C model. The installation process requires basic tools and a small soldering iron. Begin by disconnecting the power and removing the receiver’s cabinet. The clock assembly is mounted on the front panel, requiring careful handling of screws and nuts, particularly noting the placement of a short screw and sheet metal nut. Solder connections must be made with radio-grade rosin core solder, avoiding fluxes and overheating. The red-black wire is unsoldered from the line terminal strip and connected to the clock switch terminal “A”. The yellow-black and black-white wires are connected to specific terminals on the A.C. power line terminal strip. The clock shaft extension is secured using pliers, ensuring no bending occurs. After reassembling the cabinet, the clock hands are adjusted using the rear knob, and the clock switch is set to AUTO for automatic operation. The clock will run continuously when connected to a power source, but it does not automatically turn off the receiver.
Quick Issues Covered
- Diagnose power-up failures with clock-timer installation issues.
- Calibration adjustments for clock switch timing and operation.

Installation / Setup
The installation of the Electric Clock Timer Kit #38896-2 for the Hammarlund HQ-110 communications receiver involves several steps. The receiver must first be disconnected from power and all wires removed from the rear terminals. The receiver is then placed face down on a clean surface to prevent damage. The cabinet is removed by taking out screws at the rear corners and lifting it off, passing the power cord through the opening.
The plastic window and medallion plate are detached from the front panel using a Phillips screwdriver, noting the placement of screws and nuts. The clock window is inserted into the panel opening, and the clock mechanism is positioned behind the panel. The clock is secured with screws and nuts, ensuring the plastic window and mechanism are clamped properly.
Wiring involves unsoldering and connecting specific wires to designated terminals, ensuring they are dressed and tied to avoid interference with other components. A shaft extension is attached to the clock’s rear shaft, tightened securely to prevent loosening.
After installation, the receiver is reassembled by placing the cabinet back onto the chassis, aligning the clock shaft extension, and securing it with screws. The clock hands are set using knobs on the rear and front of the clock. The clock operates continuously when connected to a power source, with settings for automatic operation and pre-warming the receiver. The clock switch does not automatically turn off the receiver.
Operation
