Satellite Demo with the Philippine Navy

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).

For this demo,  I used a home-brew portable satellite radio setup and a DIY satellite antenna.

STAMINA 4 SPACE awards DIWATA 2 Testers

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

  1. Jharwin Barozzo, DV2JHA (Phillippines)
  2. Anthony Guiller Urbano, 4I1AWN (Philippines)
  3. Joseph Petruff, 7J1ADJ/JR6 (Japan)
  4. Afer Shi, BG5UTE (China)
  5. JS6DRQ (Japan)
  6. Iji Yoshitomo, JA6PL (Japan)
  7. Brian Santos, DU1MS (Philippines)
  8. JR6DI (Japan)
  9. Hong Liu, BH4ESB (China)
  10. 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.

The testing team will continue to assist the STAMINA4SPACE program in monitoring the status of DIWATA2’s Amateur Radio Unit.
