Amateur radio satellites are orbiting relay stations that enable long distance communications using only a two-way radio and a home-brewed antenna. Unlike other communications systems like the cellular service and the Internet, satellites do not rely on ground-based communications infrastructure. If a locality is hit with a major disaster, damage to infrastructure will render the cellular phones and the Internet unusable, but satellites in space will continue to function. In this talk, I’ve discussed how to access these amateur radio satellites, and explained how to setup a home-brewed satellite phone for reliable communication in times of disaster.

I was invited to conduct a live satellite demo at the Philippine Navy as part of the exit presentation of DOST-Balik-Scientist CDR Leo Almazan USN (ret) at the Pascual Ledesma Naval Station in Cavite, Philippines. We’ve accessed DIWATA2 (PO-101) and had successful contact with JA6PL (Japan), DV2JHA (Pangasinan), and DU1ELT (Cotabato).
Prior to the service announcement, a small group of volunteer amateur radio operators worked with the engineers from STAMINA4SPACE Program (formerly named as the PHL-MicroSat Program) to test the full capabilities of DIWATA2’s Amateur Radio Unit. The scope involves testing the receiving (RX) and transmitting (TX) capabilities of the satellite both for voice mode and data mode. It also includes determining the kinds of antennas, the clarity of voice communication, and how much power is actually needed to access the satellite.
Plaques of appreciation were awarded to the first 10 stations to ever access DIWATA 2, and certificates for those involved in the testing efforts.
First 10 Stations to make a successful QSO via DIWATA2 Satellite
Anthony Guiller Urbano, DU1AU (Philippines), formerly 4I1AWN
Joseph Petruff, 7J1ADJ/JR6 (Japan)
Afer Shi, BG5UTE (China)
Iji Yoshitomo, JA6PL (Japan)
Brian Santos, DU1MS (Philippines)
Hong Liu, BH4ESB (China)
Stanley Sumping Anak Albert Bejie, 9W8DNX (Malaysia)
For assisting with the testing efforts and achieving one of the firsts QSOs via DIWATA2, special awards were given to
Percival Padilla, DV1XWK (Philippines)
Lee Castor Canono, D8BVK (Philippines)
Veronica Catherine Anak Nohan (9W8VWW, Malaysia)
The awards were given on April 26, 2019, at the Electrical and Electronics Engineering Institute Bldg., University of the Philippines, Diliman, Quezon City, through AMSAT Philippines president Atty. Eduardo Victor Valdez, PHL-50 project leader Dr. Marc Caesar Talampas, and STAMINA4SPACE program leader Dr. Joel Joseph Marciano Jr.
