My portable satellite radio setup won 1st place (VHF-UHF category) in this year’s go-kit (portable equipment) contest as part of the 87th anniversary of the Philippine Amateur Radio Association. It is essentially a satellite phone with collapsible antenna which allows communication with anyone, anywhere in the Philippines and neighboring countries such as Japan, Malaysia, China, Korea, Indonesia, India, Sri Lanka, Singapore, Vietnam, Hong Kong, Taiwan, and even Australia, using only a transmit power of 5W.
The go-kit was built in April 2019 to help the STAMINA4SPACE test our country’s first amateur radio satellite DIWATA2.
AMSAT Philippines, Inc. featured satellite communications equipment in celebration of the 87th anniversary of the Philippine Amateur Radio Association (PARA) on November 23, 2019, in Marikina City, Philippines.
The exhibit showcased Jharwin Barrozo’s (DV2JB) fully-automated home-brewed motorized satellite tracker, Anthony Urbano’s (DU1AU) portable satellite radio equipment setup, Servillano Boy Avila’s (DV4SMA) satellite go-box, and various types of satellite antenna by Ronald Navarro Pece (4I1AGI) and Jesus Ramises Mella (4G1BKZ). With a satellite communications equipment, one may contact anyone, anywhere in the Philippines and neighboring countries such as Japan, Malaysia, China, Korea, Indonesia, India, Sri Lanka, Singapore, Vietnam, Hong Kong, Taiwan, and even Australia, using only a transmit power of 5W— an alternative mode of communication in emergency situations.
AMSAT Philippines, Inc. is a PARA-affiliated amateur radio group specializing in satellite communications with Ed Valdez (DU1EV) as its president.

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.

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.

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’ve received 6 SSTV images from the International Space Station (ISS) from August 3-4, 2019, from my amateur radio station in Bacoor, Cavite, using a DIY antenna and a portable radio. The app Robot 36 was used to decode the SSTV transmissions. For participating in the SSTV event, I was awarded a certificate.

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).
I have received these cards from BG5UTE (China), for our contact on various satellites on April and May, 2019. Shi sent me a QSL-card confirming each of our first contacts in AO-91, AO-92, SO-50, and PO-101 (DIWATA 2). The cards’ cover features a photo of an Iridium satellite flare taken by BG5UTE himself! Thanks for these cards, I’ll be sending mine soon!
