DIWATA 2 Test (March 2019)

Here’s a demonstration on how I used an FT60 with power of 5W to access Diwata 2 satellite during its testing phase. In the video, I have successfully made contact with stations in Pangasinan and in Okinawa, Japan, from Sta. Rosa, Laguna. Notice how I tracked the satellite using a home-brewed antenna.

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.

QSL Card from DX1O

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!

PARA operators spearhead DIWATA2 testing

A group of amateur radio operators from the Philippine Amateur Radio Association (PARA) worked with the engineers of STAMINA4SPACE Program (formerly named as the PHL-MicroSat Program) to test the full capabilities of DIWATA2’s Amateur Radio Unit. The task 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. The testing effort lasted for two months, usually requiring operators to stay up until 1 am just to track the satellite at it passes over the Philippines, using a number of radio equipment and satellite antenna. DU1EV Eduardo Valdez, president of PARA and president of AMSAT Philippines, coordinated the frequency assignment of the satellite and its call sign DW4TA. The first successful contact made through the DIWATA2 microsatellite was on March 01, 2019, 1:27 AM, local time, between DV2JB Jharwin Barozzo (Dagupan, Pangasinan) and STAMINA4SPACE engineers 4I1DIT JP Almonte and Lorenzo Sabug operating as 4I1BBE (UP Diliman, Quezon City).

Plaques of appreciation from STAMINA4SPACE were awarded to the first 10 stations to access DIWATA 2, and certificates issued to those involved in the testing efforts. The AMSAT-PH club call sign DX1O was used as the event’s official call sign.

First 10 Stations to make a successful QSO via DIWATA2 Satellite

  1. Jharwin Barozzo, DV2JB (Phillippines, AMSAT), formerly DV2JHA
  2. Anthony Guiller Urbano, DU1AU (Philippines, AMSAT), formerly 4I1AWN
  3. Joseph Petruff, 7J1ADJ/JR6 (Japan)
  4. Afer Shi, BG5UTE (China)
  5. JS6DRQ (Japan)
  6. Iji Yoshitomo, JA6PL (Japan)
  7. Brian Santos, DU1MS (Philippines, PARL Inc.)
  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, ARCOTP Inc.)
  • Lee Castor Canono, D8BVK (Philippines)
  • Veronica Catherine Anak Nohan (9W8VWW, Malaysia)
  • Leo Madrid Almazan (WA6LOS/DU3ZX, a DOST Balik-Scientist)

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 and PARA 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.

DIWATA2 Live Satellite Demo

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 Iji Yoshitomo (JA6PL, Japan) and JR6DI (Japan).
