The South African Amateur Radio League (SARL) is the latest national society to make their magazine freely available to all in the convenient PDF format.

The magazine features a QO-100 Dual Patch antenna article by David ZR6DLG and the ARISS Interoperable Radio System.

The SARL say:

The Council has decided that the April 2020 issue of Radio ZS is available for members and not yet members of the SARL. Click on the link on the front page of the League website to download a copy. Read on page 10 and 17 about My Project and how to win a membership to the SARL. On page 11 you can read about SARAH or Southern African Radio Active Ham.

You can download the PDF of the April edition of Radio ZS, published by the South African Radio League from

SanoSat-1 PocketQube Satellite

Spain’s AMSAT EA is registering the AMSAT Nepal SanoSat-1 satellite with IARU and the ITU, due to the difficulty of carrying out this procedure in the Asian country.

A translation of a post by the Spanish national amateur radio society in Spain URE says:

This is a one-off collaboration, which will allow said satellite to fly under the Spanish flag, being launched jointly with the EASAT-2 and Hades satellites of AMSAT-EA, predictably with SpaceX later this year.

SanoSat-1 is a 5cm side PocketQube 1P designed and developed affordably for the hobbyist community by using readily available commercial components (COTS).

The SanoSat-1 satellite integrates a gamma radiation sensor as a payload. Its main mission will be to measure space radiation while orbiting, and periodically transmit its level to Earth using RTTY-FSK modulation. All radio amateurs will be able to receive and decode radiation measurement data.

The secondary mission of the SanoSat-1 satellite is also to demonstrate the storage and forwarding concept, which will be useful in remote disaster-prone locations. The satellite will collect data from ground sensors, store it on board and transmit it to Earth’s main station. The design and kit for the ground sensors will be made available to the general public.

One of AMSAT Nepal’s goals is to encourage more people to join the group of radio amateurs by receiving data from SanoSat-1, which will also issue a CW beacon with its internal status.

Another activity scheduled to promote radio amateurs and satellite technology to science and technology students around the world is the organization of hands-on workshops on the construction of pico-satellites and ground stations. There will be an opportunity to build an affordable open source ground station (SatNOGS) and a dedicated GFSK receiver ground station to receive the data.

The design of the satellite itself will be open source as well.

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-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
