Case Study: Tiny oscillator, big impact for radio exam training

Tiny oscillator, big impact for radio exam training

Training new amateur radio operators should be challenging, but not held back by equipment. When an antenna manufacturer approached ABL Circuits to build a miniature oscillator for AM radio intermediate licence exams, they needed a PCB supplier who could match their design, shrink it, assemble it and test it - all to a pretty tight deadline.

The client provided the schematic and basic layout. Our expert engineers refined the design and compressed it into a compact 30 mm × 30 mm board without compromising functionality. From order to delivery, including board design, manufacture, assembly, and rigorous testing -  everything was done in under one week.

For cost-efficiency, we panelised 42 boards per panel, then cut them to size. The final boards go into kits used by radio clubs for training, and are part of larger transmitter/receiver kits. Because ABL Circuits handles everything locally, in-house in Baldock, the client benefits from UK production standards, fast turnaround, and reliable quality - enabling them to keep stock lean and training schedules on track.
