This plan was conceived in December 2023 and aimed to create a portable, compact, power-equipped radio with a transceiver that could be remotely controlled via the internet. The primary focus was portability, and subsequently, we gradually designed the functional architecture, including both software and hardware development. In January 2024, we began selecting an enclosure box. After reviewing many options, we chose a 20x15x5cm box that was appropriately sized, and we selected CNC-machined panels to ensure a solid and aesthetically pleasing finish.
Then came the long process of developing the software system, starting from a single line, a rectangle, a character, and a menu on the screen, to eventually creating a complete graphical user interface. This required countless hours of work, repeated debugging, and constant optimization. Once the initial software was completed, we immediately started designing the circuit board. Designing the circuit board was also very challenging because it had to be extremely small, similar to the FT891, and capable of handling 1000W SSB while minimizing interference. The biggest challenge was dealing with interference. Throughout the process, we repeatedly tested and adapted the software system for compatibility. After a long period of intense work and testing, we finally released the first beta version in April 2025. Many friends helped us test the beta version, but both the software and hardware were still incomplete. However, everyone eagerly awaited the release of the beta version. During the beta testing, we encountered many problems, with interference being the most significant issue. The small size and high power made it very difficult to manage. To address this problem, I researched extensively and even participated in EMC seminars. It took about six months to solve this problem. Once the interference issue was resolved, I looked at the sample quantities that Jia Li Chuang produced, which were already over 50 sheets, and they were large boards measuring 15x20cm. The EMC problem is a bit of a mystery, but solving it requires patience. Dealing with this interference has also tempered my personality. In the end, I learned the phrase "Good things come to those who wait."
After two years of development, the final version has been established, and the product is now in mass production. The software system is also updated daily, with continuous innovation and upgrades.
Many of our partner stations value its portability and remote functionality, which makes it very practical and convenient to use.
