None of these proposals are adopted at this time and work will continue at the next meeting of WP5A to rationalise the variations proposed by national telecom-administrations.
The IARU will work to minimise the constraints on amateur radio activities and continue to seek amendments to the draft recommendations through the ITU process, but as a secondary user, radio amateurs should understand the need to protect the Radionavigation Satellite Service (RNSS) in many consumer and industry applications (like autonomous vehicles) that will lead to some restrictions on our use of the 23 cm band.

Russian cosmonauts on the International Space Station (ISS) are planning to transmit Slow Scan TV (SSTV) images on 145.800 MHz FM probably using the SSTV mode PD-120.
The transmissions are part of the Moscow Aviation Institute SSTV experiment (MAI-75) and will be made from the amateur radio station RS0ISS in the Russian ISS Service module (Zvezda). This will be the first time the experiment will use the recently installed Kenwood D710GA.
• June 8 Setup and activation 09:45-10:15 GMT, stop about 15:00 GMT*
• June 9 start about 08:35 GMT, stop about 16:15 GMT*
*Dates and times may be subject to change.
The signal should be receivable on a handheld with a 1/4 wave whip. If your rig has selectable FM filters try the wider filter for 25 kHz channel spacing.
