New startpage for amsat.se

Starting today we are testing a new startpage for amsat.se. The three most asked question now has large menu items (in Swedish).

It is “How to start listen”, “How to make first QSO” and “What satellites are QRV?”

Latest news posts can be found under these menu items.

Hopefully this can lead to more visitors find beginner information quicker.

AM1SAT Satellite Contest, September 2023

Info from AMSAT-EA and ANS-225:

AMSAT-EA will be on the air on all available satellites with the callsigns AM1SAT and AM2023SAT from September 4th to 17th, 2023 to celebrate the fourth edition of the AM1SAT trophy contest as part of the URE activities within the IberRadio 2023 event, the largest one in the world of amateur radio in Spain and Portugal (http://www.iberradio.es), and which will open its doors during the weekend of 16-17 in Avila, a city near Madrid, capital of Spain.

The AMSAT-EA operators will activate the aforementioned callsigns from the different states and autonomous cities of Spain during the said period of time and with the objective in this edition to promote contacts with the maximum number of them.

As part of this activity and to encourage participation, SILVER and GOLD diplomas will be available for the different modalities of satellites according to their footprint and orbital height, LEO, MEO (IO-117 satellite) and GEO (QO-100 satellite), as well as a trophy for the station that works the greatest number of states in the total number of available satellites and another trophy for the one that contacts the greatest number of states on the satellite with the largest footprint and coverage (in this case, IO-117). These trophies will be physically sent at no cost to the winners.

The third edition of the AM1SAT satellite contest, in 2021, finished with 1327 QSOs including GEO and LEO contacts, with 57 different radio-countries, using 20 satellites and with the participation of 419 different competitors (callsigns).

Nooelec Ham It Down 3GHz downconverter

Nooelec, manufacturer of LNAs and SDR equipment, releases a new downconverter. It is designed to convert signals from the 1.55 GHz to 3.1 GHz range into the frequency range of software-defined radio devices like RTL-SDRs.

Initial price is set to around 90 US$ and it makes it an interesting product for S-band RX if you have a SDR since before.

Two new digipeating satellites coordinated

ROM-3

According to IARU two new satellites, Veronica and ROM-3, has been coordinated and are planned to launch during 2023. Following are info from ANS-218:

Veronika
From the Technical University of Kosice, Veronika is a 1U CubeSat scheduled for launch on a Falcon 9 launcher on the Transporter 9 mission in October 2023. The satellite will be equipped with a 24/7 digipeater on two different bands, as well as experimental SSDV transmissions.

The satellite also has an education and outreach mission in that it is planned to involve Slovak grammar and high schools and to transmit special CW and AX.25 messages on several special occasions. From a platform perspective, the satellite will be equipped with a novel ADCS subsystem, including electromagnetic actuators and a GNSS receiver. This will also help to identify the satellite during the first days and weeks. The satellite will communicate o using Spacemanic’s well-known Murgas transceivers (BDSat-1, BDSat-2, Planetum-1).

Altogether, Veronika will provide: AX.25 telemetry; a CW beacon; a digipeater; AX.25 & CW messages on special occasions for community engagement; Experimental SSDV transmissions; and SATNOGS integration, decoder and dashboard. A downlink on 436.680 MHz has been coordinated and will use 9k6 G3RUH AX.25 and a CW beacon. Planning a SpaceX launch on Transporter 9 mission in Q4 2023 to a 500/600km polar orbit .

ROM-3
From the Romanian Radioamateur Federation, ROM-3 is a 50 x 50 x100mm picosat with three missions and objectives. Its primary mission is to act as a digital amateur radio repeater. Its secondary mission is to transmit low-resolution SSDV images in a GFSK Mode. The tertiary mission is to transmit a CW beacon that will help amateur radio operators detect the presence of the satellite and measure basic properties of the signals such as its strength, fading due to spin, Doppler to measure speed, etc. A downlink on 436.235 MHz has been coordinated for 20 wpm CW, 500bps GFSK telemetry and 5kbps GFSK SSDV. Planning a SpaceX launch in October or November 2023 into a 500km polar orbit. More info at https://rom-space.ro
