More than 50 amateur radio satellite enthusiasts attend two live satellite contact demonstration conducted by the AMSAT Philippines, Inc., Stamina4Space, and Holy Angel University, on September 28, 2019, in Angeles City, Pampanga. The live demo events were part of an amateur radio satellite seminar and antenna workshop.
The video recordings below show the two demo events featuring voice communications via AO-91 and PO-101 (DIWATA2) satellites. The official AMSAT Philippines, Inc. call sign DX1O (Delta X-ray One Oscar) was used during the event, with Anthony Urbano (DU1AU) as the operator.
Demo No. 1 Satellite: AO-91 (Fox-1B) Time: 04:09 to 04:24 UTC Elevation: 51 deg Operator: DU1AU (Angeles City)
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).
During the DIWATA 2’s (PO-101) testing phase, a special call sign was heard on the satellite: DX1O of AMSAT Philippines. Shortly after a successful QSO with DX1O, I have received the special e-QSL card below:
Later I found out that I was one of the first few stations to make a successful contact via DIWATA2 and was given an award for it. Thank you DIWATA2 Team and AMSAT Philipines!

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.
We have successfully conducted a live demonstration of DIWATA2’s Amateur Radio Unit, showcasing the satellite’s capability to relay signals not only to and from any point in the country, but to other nearby countries as well. In this demonstration held earlier today in UP Diliman, Quezon City, an inexpensive home-brewed antenna connected to a low-cost radio transmitter was used to access the DIWATA2 satellite. Contact was established via satellite among the amateur radio operators in various location: Anthony Guiller Urbano (4I1AWN, Quezon City), Jharwin Barozzo (DV2JHA, Pangasinan), JP Almonte (4I1DIT, Quezon City), and other stations from Japan such as IjiYoshitomo (JA6PL, Japan) and JR6DI (Japan).
