Belgium: 23 cm band Restrictions

2024-03-27 Belgium 1240-1300 MHz proposed restrictions

2024-03-27 Belgium 1240-1300 MHz proposed restrictions

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

Belgium is believed to be the first country to propose restrictions on 23cm band operation following WRC-23 ITU-R Recommendation M.2164-0

The new restrictions include:

Class A (equiv UK Full, USA Extra) – size of band reduced from 60 MHz to 8.24 MHz. EME (but not satellite uplink) is permitted 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

SSA defends 23cm band against Galileo threat

Galileo LogoSweden’s national amateur radio society, the SSA, has sent a supplementary letter to the communications regulator PTS ahead of the next meeting of the CEPT ECC Conference Preparatory Group CPG-19.

The SSA report:

At a previous CEPT meeting (PTA), France has proposed an agenda item to WRC-23 that the coexistence between satellite navigation (eg Galileo) and amateur radio in the band 1240-1300 MHz should be investigated. The proposal was voted down at the preparatory PTA meeting, but France has now sent letters to the various telecommunications authorities with a request that they now support this proposal at the forthcoming CPG19-9. SSA opposes this.

SSA has therefore sent a supplementary letter to PTS about our 23 cm amateur band. Our section leader for IARU and VUSHF Mats SM6EAN explains the background and our opinion on our section pages. Here you can also read the new letter to PTS.
