On June 19, 2025, shortly after the launch ceremony at 06:00 UTC, we conducted a successful trial satellite communication operation at the Pakubuwono Ground Station. The trial, a significant milestone in our ongoing efforts, demonstrated seamless communication via the IO-86 and RS-44 satellites, establishing successful QSOs (contacts) with stations in Indonesia and other countries.
Trial Highlights
During the 14-minute pass of the IO-86 satellite, our team, led by Muhammad Yasir Zain (YF3FEO), President of Amsat Indonesia, operated the station and successfully completed QSOs in FM mode with the following stations:
- YC2YIZ and YD2UUY from Yogyakarta, Indonesia
- YD9MBM from Kupang,, Nusa Tenggara Timur, Indonesia
- YC8RPK from Bitung, Sulawesi Utara, Indonesia
- YD9IQX from Nusa Tenggara Barat, Indonesia
- DU9JJY an amateur satellite operator from The Philippines
Additionally, SSB mode communication was conducted via the RS-44 satellite, resulting in successful QSOs with VU2LBW, a member of Amsat India, and another contact with DU9JJY from the Philippines.
Equipment and Performance
The trial utilized our main radio setup, which included:
- ICOM IC-9700 transceiver
- Yaesu G5500 antenna rotator
- VHF/UHF X-Quad antennas
A backup radio setup was tested on a separate day, ensuring operational redundancy. The satellite communications performed flawlessly, exceeding expectations and validating the reliability of our equipment and operational protocols.
Looking Ahead
The success of this trial operation underscores Amsat Indonesia’s commitment to advancing satellite communication capabilities. The setup demonstrated during this operation also complies with the technical requirements for establishing contact with the International Space Station (ISS), marking a significant step toward future ISS communication opportunities. We are thrilled with the results and look forward to further refining our operations and fostering collaboration with amateur radio communities across the region.
