On Friday, October 7, 2022, from 15:14 GMT there will be a amateur radio contact from Antarctica with the International Space Station (ISS).
Students from the #38 Raul Alfonsin school at the Esperanza Antarctic base will ask questions that will be answered by astronaut Kjell Lindgren, KO5MOS, aboard the ISS, with a telebridge link being provided by ON4ISS, AMSAT Belgium.
This event was managed before ARISS (Amateur Radio on the ISS) by CETRA (Science, Education and Technology united by Amateur Radio) subcommission of AMSAT-LU, led by Luis Funes, LU8YY/Q, NASA/ARISS Telebridge.
AMSAT thanks COCOANTAR (ANTARCTIC Joint Command) for their collaboration and commitment to make this special event possible (1st Contact of the ISS with Antarctica), and to ARISS Canada for their valuable support.
This adds to the WSPR LU1ZV beacon active in Antarctica donated by AMSAT-LU.
It can be seen on https://www.instagram.com/coconatar/?hl=es and broadcast by COCOANTAR, TN and graphic and television media.

It was half day (10:00 AM to 02:00 PM IST) interactive workshop full of presentations, Audio Visual Documentary, Practical Demos, Q & A sessions and Radio stuff Exhibition with live operation.
There were 80 B.Tech students participated from ICT Dept + MU’s Student Satellite Project team. Yes Marwadi University has announced to build a Student Satellite and to be launched by ISRO!
Our ham team includes YL Sakshi Vagadia VU3EXP & YL Shyama Vagadia VU3WHG, both member extended great support to setup VHF station, organise & display Radio Stuff and assisting in practical demos including SSTV, Digital & VHF FM Demo with groups! Btw Shyama VU3WHG also remains one of the student coordinator of this event as well as Team member of Student Satellite Project.
All participants gained knowledge on broad spectrum of topics from CW to Cube Satellites! In first session Radio Fundamentals, operating protocols, radio jargons, licensing procedure etc were covered. In second session participants were briefed with various Ham radio events like FD, Hilltop, Light House activation, POTA, IOTA, EME, Satellite tracking, SatCom, High Altitude Balloon tracking, ARISS SSTV & Student outreach program which gives exposure to gain knowledge & develop skills from outside radio Shack activities also!
Lots of fruitful discussion happens during workshop and students were satisfied with all of their queries.
In workshop we had gracious presence of Shri Naresh Jadeja (Registrar), Dr. R. Sridaran (Dean), Dr. Jaypalsinh (MCA Dept), and Dr. Shobhit Patel (Researcher). We also get positive response from Marwadi University authorities to be engaged with AMSAT-INDIA to conduct more programs & projects in upcoming period for benefit of student community.
We also thank to Shri C. D. Parmar Sir (HOD ICT) and Program Coordinator Prof Mitesh Solanki for all the great support provided to make this workshop successful.
I am glad to notice this Ham workshop created a Ham buzz in the Marwadi University campus. For me too it was great honor to present & share my best knowledge amongst budding engineers on the occasion of Engineering Day!
Thank you

However the IARU is not content that all the operational aspects of the amateur service usage of the 1240-1300 MHz band are being properly considered to develop an acceptable compromise for all concerned parties.</p>
<p>Having been deeply involved in the regulatory work described below it is the opinion of the IARU that for many national authorities the 23cm band WRC23 agenda item 9.1b topic has a very low priority. Many are taking a “generic” stance stating their support for studies without considering the detail of the work or how it is moving forward. Therefore the IARU requests that Member Societies urgently put this issue on the agenda with their national authorities to discuss the views laid out below.</p>
<p>The IARU view is that the potential for widespread or persistent interference to the radio-navigation satellite service (RNSS) from amateur service transmitters is over-stated. However, recognising the regulatory situation, the IARU and the amateur community are ready to accommodate any technical or operational measures deemed necessary on the amateur services so long as they are proportionate, reasonable and evidence based.</p>
<p>The IARU believes that a careful compromise needs to be found in the outcome of the work and the execution of WRC-23 agenda item 9.1b, that properly takes account of the low likelihood of interference events occurring whilst allowing both the amateur services and the RNSS to develop in the band.</p>
<p>The IARU stresses the opportunity that the higher frequency amateur service bands enable for technical skills development for researching and experiencing radio propagation effects. The 1240 – 1300 MHz band is important for the amateur radio service, being the lowest allocation for radio amateurs on which typical microwave propagation can be experienced. Access to these frequencies is facilitated by commercially available equipment and provides a ‘bridge’ building motivation to become involved in more specialized higher frequency microwave and millimeter wave operations providing the self-training which is at the heart of amateur radio.</p>
