INTRODUCTION ■■ What is D-STAR? ••D-STAR is a digital protocol standard developed by the Japan Amateur Radio League (JARL). The system includes the DV mode for Digital Voice and the DD mode for Digital 1 Data communications. ••D-STAR supports the DV mode at 4.8 kbps. Your call sign data, and either a short 2 message, or GPS data can be transmitted simultaneously with your voice signal. ••D-STAR supports a comprehensive repeater system linked through the Internet, 3 enabling you to make QSOs with stations near or far from your location. 4 Advanced Amateur radio technology of D-STAR The DV mode has a bandwidth of only 6 kHz, compared to 16 kHz for the analog FM 5 mode, with 5 kHz deviation. D-STAR utilizes the well-know GMSK modulation method that makes very efficient use of occupied bandwidth. 6 D-STAR (F7W) 7 8 10 kHz fo 6 kHz Frequency 10 kHz 10 kHz 10 kHz 9 D-STAR occupies 10 kHz. The sound quality is good 10 even though the bandwidth is narrow. 11 12 13 14 20 kHz 20 kHz 15 FM (F3E) 16 17 The regular FM mode 18 fo 16 kHz Frequency occupies 20 kHz that is double the bandwidth of 10 kHz 10 kHz 10 kHz 10 kHz D-STAR.
