This is an acoustic filter that improves the reception clarity of amateur radio Morse communication (CW).
【Overview of this product】 ◎ This is an acoustic filter that improves the reception intelligibility during Morse communication (CW) for amateur radio and similar applications. ◎ It is a kit that requires assembly, including soldering several electronic components and securing screws (the DSP board is already completed). ◎ It incorporates a 400MHz DSP (Digital Signal Processor) with 24-bit AD/DA and a sampling frequency of 48kHz, enabling fast and high-precision signal processing. ◎ The filter bandwidth can be quickly switched in the order of pass → 400Hz → 200Hz → 100Hz → 30/25Hz → pass, allowing for rapid response to interference and fluctuations in the frequency of the other station. ◎ The CW pitch (filter center frequency) can be set in 100Hz steps within the range of 300 to 1000Hz.

Company information
In 2021, we became an independent entity within the Kernel Group as Kernel Hard Engineering Co., Ltd. to develop our own brand of system products, including hardware. The Kernel Concept, which serves as the foundation of the Kernel Group, was established in 1985. Under a close relationship with local manufacturing industries, we have been involved in the development of embedded software and have continued to grow as a mid-sized independent IT company in the Chubu region, one of Japan's manufacturing hubs. The various systems produced from the technical, organizational, and human resources we have cultivated over our 35-year history are highly regarded for their quality. Through the natural expansion of our technological connections, we have also built a track record in the fields of FA, CAD/CAM/CAE, and in recent years, we have been actively engaged in system development utilizing the web and cloud technologies. Currently, the entire Kernel Group has approximately 1,000 employees.
