Amateur radio satellite spreads Fight Coronavirus message

LAPAN-A2 (IO-86)

LAPAN-A2 (IO-86)

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-BR QO-100 FT8 QRPp Experiment

AMSAT-BR Logo and Dish AntennaAMSAT-Brazil is organizing a reverse beacon FT8 QRPp experiment/contest via the QO-100 geostationary amateur radio transponder.

The first 10 spotted stations with lower SNR will receive a Certificate of Accomplishment.The dead line will be May 1st 2020. To qualify, the SNR must be lower than -18 dB (as measured by the ft8 decoder). The receiver will be active on Saturdays and Sundays from 12:00 UTC to 24:00 UTC and will be tuned to 10.489540 GHz with a 3.5 kHz bandwidth. All stations calling CQ will be logged.

The objective for the project is to incentive low power experimentation through the QO-100 narrow band transponder. Stations participating in the experiment are welcome to send a brief description of their setup, including information about RF power output, hardware and software setups, antenna type and gain, photos, etc. to the email address

Project for school QO-100 amateur radio stations

Es'hail-2 Qatar-OSCAR-100DARC reports on a Practical Seminar about the amateur radio QO-100 geostationary satellite transponders. Part of seminar fees goes to the “School stations on QO-100” project.

A translation of the DARC post reads:

Top-class seminar in the DARC office in Baunatal: On February 28, experts from AMSAT-DL e.V. gave around 40 people a detailed insight into the possibilities offered by the QO-100 amateur radio transponders on the geostationary satellite Es’hail-2.

AMSAT-DL President Peter Gülzow, DB2OS, started with a keynote speech. Workshops with four lecturers dealt with different operating modes, different hardware concepts and readily available software solutions for the PC.

Part of the attendance fee will go to the joint project of DARC and AMSAT-DL “School stations on QO-100”. Together they want to equip ten schools that already have a training call sign with a complete reception system for the narrowband transponder.

DARC and AMSAT-DL want to motivate more young people for amateur radio through the possibilities that QO-100 offers.

Ham radio QFH satellite antennas built at workshop

Participants built QFH antennas at the ORARI workshop

Participants built QFH antennas at the ORARI workshop

Radio amateurs built Quadrifilar Helicoidal (QFH) satellite antennas at a workshop in Indonesia organised by a local branch of the national amateur radio society ORARI.

A translation of the ORARI website report reads:

On Saturday, February 22, 2020, South Jakarta Local ORARI Jakarta held a Homebase Antenna Workshop for LAPAN-A2 / LAPAN-ORARI (IO-86) Satellite Communications. The workshop was held at the Local ORARI Club Station in South Jakarta, with guest speaker Suryono Adisoemarta (Yono / YD0NXX).

The agenda of this workshop consists of theory and practice. Theoretical material includes the introduction of amateur radio satellites in general, the introduction of LAPAN-A2 / LAPAN-ORARI (IO-86) satellites and satellite tracking techniques. Whereas practical material includes making a Quadrifilar Helicoidal (QFH) antenna and communication with the LAPAN-A2 / LAPAN-ORARI (IO-86) satellite.

The workshop was opened at 9:20 by Irsan YC0OST as Deputy Chair of South Jakarta Local ORARI. After opening, the program continued with the giving of theories about amateur radio satellites. In addition to the IO-86 satellite, there are also other amateur radio satellites that can be used such as AO-7 as the longest-running amateur radio satellite, AO-91, AO-95 and QO-100 which is a geostationary amateur radio satellite.

After the theoretical material was finished around 11:30, the program continued with the practice material for making QFH antennas. The materials for making the antenna provided by the committee included copper capillary pipes, 1 1/4 PVC PVC pipe, RG-58 cable, BNC connector and paper clips. Meanwhile, the equipment for making antennas was carried by each participant, such as solder, scissors, pliers, drill, and others. The atmosphere became even more exciting, because in making this QFH antenna there were separate challenges, especially in the RG-58 cable connection to the antenna element.

At 14:00, LAPAN provided a dedicated Voice Repeater slot on the IO-86 satellite for workshop participants to try out the antenna they made. But because the antenna is quite complicated, there is no antenna that can be tried on the Voice Repeater schedule. Mahesa Rani YD0OVE’s antenna was first tried on the regular Voice Repeater schedule. The results are quite satisfying. With her capital Handy Transceiver (HT) and a hand-held QFH antenna, YD0OVE successfully received 14 amateur radio stations.

In this workshop, several guests were present including the President of AMSAT-ID Hakim YB0AN, Chair of the Central Jakarta Local ORARI Edy YCØEDY, and the South Jakarta Local ORARI DPP Beben YB0HJW and Fahlifi YF0BRR.

AMSAT Files Comments Opposing Deletion of 3.4 GHz Band

FCC SealAMSAT has filed comments on the Federal Communications Commission’s Notice of Proposed Rulemaking which proposes to delete the 3.3 – 3.5 GHz (9 cm) amateur band, including the 3.40 – 3.41 GHz amateur satellite service allocation.

In the comments, AMSAT opposes the deletion of this allocation and emphasizes the necessity of adequate microwave spectrum for future amateur satellite projects, including AMSAT’s GOLF program and the Lunar Gateway.

AMSAT further notes that the most desirable allocations for use as uplinks are the allocations between 2.4 and 5.67 GHz. These allocations total 80 MHz. The most desirable allocation for downlink use is the 10.45 – 10.50 GHz allocation, totaling 50 MHz.

As many of the proposed uses include amateur television and high-speed data transmission with satellites in high earth orbit or lunar orbit, these allocations may quickly become inadequate. AMSAT also notes that the 2.4 and 5.67 GHz allocations are widely used for ISM and consumer devices, such as WiFi and Bluetooth-enabled devices. The 3.4 GHz allocation is shared between amateur use and other non-federal and federal licensees, but is free from the unpredictable interference of consumer devices.

While acknowledging that the 3.4 GHz amateur satellite service allocation is not currently used by any amateur satellites and that it is unsuitable for worldwide communication since it is not available in ITU Region 1, AMSAT identifies a number of potential future uses for the band as worldwide usage of the other available allocations increases. These potential uses include a future amateur satellite in geostationary orbit above the Americas.

In the comments, AMSAT also noted several non-amateur satellite uses of the broader 3.3 – 3.5 GHz amateur service allocation, including its wide use in mesh networking, EME communications, and contesting.
