The manual provides detailed installation instructions for accessory items in the Hammarlund HQ-100 series communications receivers, specifically focusing on the 100 KCS crystal calibrator and the 455 KCS beat frequency oscillator kits. It includes guidance on setup, operation, and troubleshooting, emphasizing careful soldering and adjustment procedures to ensure proper functionality and stabilization of the receiver and oscillator units.
Manual Overview
The Hammarlund HQ-100 series manual provides detailed instructions for installing accessory kits, specifically the 100 KCS Crystal Calibrator and the 455 KCS Beat Frequency Oscillator. Both kits are mechanically identical, differing only in the frequency of the oscillator quartz crystals. Installation involves careful handling of the receiver chassis, ensuring all power sources are disconnected before beginning. The manual includes guidance on drilling necessary holes for mounting the kits, using a provided template to avoid damaging internal components. Wiring connections require precise soldering techniques, emphasizing the use of radio-grade, rosin-cored solder without additional flux. Calibration of the 100 KCS unit involves tuning to a known frequency, such as WWV at 5.0 MCS, and adjusting the trimmer for zero beat after a warm-up period. For the 455 KCS oscillator, zero beat is achieved using a stable CW signal and adjusting the trimmer, with further alignment adjustments made as necessary. The manual stresses careful examination of wiring post-installation to ensure no connections are disturbed.
Quick Issues Covered
- Calibrate 100 KCS unit with WWV signal for zero beat accuracy.
- Check wiring after installing 455 KCS oscillator to avoid displacement.
- Use schematics for tracing connections to 6AL5 tube socket.

Installation / Setup
The installation of accessory items in the HQ-100 series Hammarlund communications receivers involves several key steps. For receivers starting with Serial #1130, the chassis are pre-drilled for easy installation of the 100 KCS crystal calibrator and the 455 KCS beat frequency oscillator kits. For other receivers, a drilling template and dimensioned drawing are provided. It is important to use a light, clean soldering iron with radio-grade, rosin-cored solder, and to avoid using fluxes or overheating connections. The power cord must be unplugged, and all wires disconnected from the rear terminals before starting. The receiver should be placed face down on a clean towel to protect the front panel and knobs.
The installation involves removing the cabinet, unwrapping the oscillator unit, and attaching it to the chassis using self-tapping screws. The toggle switch is installed in the rear skirt of the chassis. Care should be taken when drilling holes to avoid damaging components. Wiring involves soldering specific wires to designated points on the tube sockets and toggle switch, ensuring the leads are properly routed and do not interfere with other components.
Calibration involves tuning to a known frequency signal and adjusting the trimmer on the calibrator unit or the crystal beat frequency oscillator for zero beat, allowing for a warm-up period to ensure stabilization. No further adjustments should be necessary after this process.
