We are advancing the project of development of meteor burst observation system with the cooperationof a lot of Colleges of Technology (Kosen) in the all over Japan. In our present Meteor BurstCommunication System (RANDOM), the modem function has been achieved with DSP and DSPcontrol PC. However, DSP device has been worn-out and it is not supplied stability for a longtime. Moreover, OS of PC and software development environment has become old and they arenot maintained easily. Therefore, we need a more flexible modem system to proceed on to meteorburst observation or next step study. Recent PCs and peripheral devices have high performance.The performance and the reliability of Linux have improved, too. In addition, the high performanceand flexible sound library that is called ALSA exists in Linux. So we consider that it is possible tocompose the modem with a general sound device. Then, we develop the new system only with oneSBC (Single Board Computer) and Linux. And we will construct the new Meteor Burst Observationand Communication System in cooperation with Kosen in all Japan.
