Belgium: 23 cm band Restrictions

Belgium: 23 cm band Restrictions

On March 27, 2024, Belgium’s regulator the BIPT published draft restrictions on amateur radio operation  in the 23cm (1240-1300 MHz) band.

The new restrictions include:

Class A (equiv UK Full, USA Extra) – size of band reduced from 60 MHz to 8.24 MHz. The satellite allocation is reduced to 1260-1262 MHz and the antenna elevation must always be more than 15° above the horizon and the transmission power is limited to 50 W EIRP. If the elevation is above 55° above the horizon, the power is increased to 500 watts EIRP

Class B (equiv UK Intermediate / USA General) – 1296-1300 MHz only

Class C (equiv UK Foundation / USA Technician) – No access (unchanged)

The public consultation runs until April 28 https://www.bipt.be/operators/publication/consultation-on-the-frequencies-powers-and-transmission-modes-that-may-be-used-by-radio-amateurs

UK’s SaxaVord Spaceport to launch amateur radio satellites

UK’s SaxaVord Spaceport to launch amateur radio satellites

Two more amateur radio satellites, MARIA-G (HADES-F) and UNNE-1 (HADES-E), are planned to launch from the UK’s SaxaVord Spaceport later in 2024.

Previously announced amateur radio payloads on the launch are:
ERMINAZ-1U and -1V from AMSAT-DL
GENESIS-MA and -ME from AMSAT-EA
QUBIK 5, SIDLOC-PQ-1 and -PQ-2 from Libre Space Foundation

MARIA-G

A 1.5u Pocketqube. MARIA-G will offer radio amateurs around the world the opportunity to relay FM voice and AX.25 / APRS 300 / 1200 bps communications. The satellite will also transmit telemetry with its status and voice and CW messages. This all will be achieved by implementing a SDR based FM and FSK repeater. The FM / FSK repeater will be available all time and opened by squelch level without the need of a PL tone/CTCSS.

Main mission for MARIA-G is to be a FM repeater but it will also include a simple guess game being implemented by students at Maria Guerrero High School in Collado Villalba – Madrid (Spain). The satellite will send a clue each week in CW so radioamateurs will have to solve the mystery by having all the clues.

A small experiment, developed by Fraunhofer-Gesellschaft research organization (Germany) will also fly on the satellite to make proof of concept transmissions of a TS-UNB waveform from a low Earth orbit. It will transmit a TS-UNB message according to the ETSI standard ETSI-TS-103-357. It is intended solely as a research and development project with no commercial intent, all its data public and open.  ITU modulation classification would be 100K W2DWW but the bandwidth will be narrowed. The operation of this experiment will be managed by AMSAT-EA.

UNNE-1

IO-117 GreenCube to cease operating on February 5

IO-117 GreenCube to cease operating on February 5

At 1622 GMT on Thursday, January 25, 2024 @S5Lab posted on X that the GreenCube IO-117 Digipeater would be permanently deactivated on February 5.

Designed and developed by students of Sapienza University of Rome, GreenCube IO-117 was the first satellite to carry an amateur radio payload into Medium Earth Orbit (MEO) – 6,000 km.

IARU satellite frequency coordination information https://iaru.amsat-uk.org/finished_detail.php?serialnum=784

The S5Lab post on X said:

Dear Friends,

After one year and a half of operations, it is time to conclude the GreenCube operations with the planned de-commissioning activities. After the conclusion of the nominal experiment and with the digipeater payload active for more than one year, we will pergorm the passivation operations for the satellite.

The planned passivation operations will be executed on Monday, 5 February 2024, at 00:00 UTC. From that day, GreenCube will be completely passivated and the digipeater will be switched off for good.

We want to thank everyone that endorsed, supported or participated in the mission and the radio amateur community that enthusiastically became a true part of our project. We hope that GreenCube will somehow be part of your memories of radio amateurs, space engineering enthusiasts, and we hope to involve you soon in many more adventures.

Thanks once again for the unbelievable memories shared together… See you soon!

The GreenCube Team at S5Lab
