Amateur radio satellite spreads Fight Coronavirus message

Indonesia’s national amateur radio society ORARI reports the ham radio satellite LAPAN-A2 (IO-86) is being used to send a Fight Coronavirus message using APRS.

A translation of the ORARI post says:

The satellite spreads the text message “Stay Healthy, Stay at Home #LawanCorona”.

This was conveyed by Researcher of the Center for Satellite Technology, Sonny Dwi Harsono when contacted, Friday, March 20, 2020.

Sonny explained, this action was a form of support for government policies on social distancing. The policy encourages all of us to reduce activities outside the home and interactions with others. “So this message was sent by the LAPAN A2 satellite via the APRS (Automatic Packet Reporting System) beacon which was transmitted throughout Indonesia. APRS is a text based communication system for short messages such as SMS on mobile phones. But this APRS message can only be received through HT (Handie Talkie) which has the recipient of the APRS message,” he said.

Sonny explained, messages that have been disseminated can be received by anyone by setting the HT radio frequency to 145.825 MHz. To date corona’s message has been received by dozens of members of the Indonesian Radio Amateur Organization (ORARI) spread throughout Indonesia.

The dissemination of the message “Stay Healthy, Stay at Home #LawanCorona” , continued Sonny, was carried out starting March 20, 2020. For the time being the message dissemination was carried out on the APRS mission only. But it will try to spread the message one time at a LAPAN-A2 / LAPAN-ORARI track every 100 minutes. “Later if possible, we try to distribute 24 hours nonstop every 100 minutes under certain conditions. Currently we are discussing the technicalities. The messages from the government can also be disseminated via the LAPAN-A2 satellite, “he concluded.

AMSAT Argentina drifting Buoy on 145.825 MHz APRS

AMSAT Argentina LU7AA drfiting BuoyOn Thursday, January 30 at 1400 GMT AMSAT Argentina will deploy drifting Buoy on South Atlantic Seas that aims to transmit APRS on the satellite packet frequency of 145.825 MHz. WSPR will also be transmitted.

AMSAT Argentina report:

The APRS beacon, callsign LU7AA-11, will initially be on Argentina’s APRS frequency of 144.930 MHz but will change frequency to 145.825 MHz so that it can be digipeated by the amateur packet radio satellites.

The WSPR beacon will run 900 mW on 14095.6 kHz with the call sign LU7AA.

Release will be 100 km offshore Mar del Plata coast, seeking east aiming currents/winds.

Objective: Sea currents tracking and HF/VHF/SAT QRPp propagation tests.

AMSAT Argentina, LU7AA, will appreciate WSPR stations receiving/reporting 20m.

Ham radio APRS payload to launch April 1

PSLV-C45 orbital platform PS4

PSLV-C45 orbital platform PS4

An APRS payload from AMSAT INDIA will be flown on the PSLV-C45 mission expected to launch on April 1, 2019 at 03:57 GMT.

On the AMSAT Bulletin Board Nitin VU3TYG writes:

The payload will be powered on approximately over Sweden, Norway, Denmark, Finland, Poland and Moscow. We request stations at these locations to report the first signals on 145.825 MHz from the payload.

We also request the Amateur Radio fraternity worldwide to use the payload and Satgates to feed the traffic. More details about this unique project as well as the prelaunch TLE are available at

It is understood the PSLV-C45 mission will deploy 29 satellites. The 4th stage of the rocket (PS4) will become an orbital platform in a 485 km orbit hosting three payloads:
• Automatic Packet Reporting System (APRS) digipeater from AMSAT INDIA
• Automatic Identification System (AIS) from ISRO
• Advanced Retarding Potential Analyzer for Ionospheric Studies (ARIS) from the Indian Institute of Space Science and Technology (IIST).

JAXA to launch FM voice transponder satellite Diwata-2

Diwata-2 satellite

Diwata-2 satellite

The Philippine Diwata-2 satellite carrying an amateur radio FM transponder and APRS digipeater is expected to launch in October.

The Business Mirror reports:

The 50-kilogram satellite shall soon be sent into orbit by the Department of Science and Technology (DOST) through its partner, Japan Aerospace Exploration Agency (Jaxa).

It should be recalled that the DOST had the Philippines’s first microsatellite—the maiden Diwata-1 that was designed, developed and assembled in Japan by nine pioneering Filipino engineers and scientists along with their “sensei” (instructors) from the Tohoku University (TU) and Hokkaido University (HU).

Diwata-1 was launched into the International Space Station onboard the Orbital ATK’s Cygnus spacecraft on March 23, 2016. It was deployed from the ISS into her orbit on April 27 by the Japanese Experimental Module (JEM)—”Kibo” or Hope—around 400 km above Earth’s surface.

Now, two years and four months later, the government is about to unveil the second iteration of Diwata-1—named Diwata-2 targeted for launching onboard Jaxa’s H-IIA rocket from Tanegashima Island in Japan.

Ariston Gonzalez, a researcher/lead research and development engineer for PHL-Microsat at DOST-Asti, is quoted in the article as saying:

“All one has to do is tune in [a ham radio] to the frequency of Diwata-2 to send voice messages while the other party stands by to receive the voice message.”

“target use for ham radio [of Diwata-2] is for emergency situations wherein all commercial communications are down.”

“What Diwata-2 does is to serve as a relay or connecting point for two persons communicating with each other,” he pointed out.”

“One can also store messages on Diwata-2 that can be broadcasted repeatedly across and over the Philippines, such as prerecorded emergency messages in times of disasters, calamities and other kinds of emergency.”

The IARU has coordinated these frequencies for Diwata-2:
– 145.900 MHz downlink
– 437.500 MHz uplink
