How Can Open Research Institute Help *You*?

Thank you so much for visiting with us at QSO Today Ham Expo! We hope you found it as enjoyable, vibrant, and inspiring as we did.

We presented five talks, had three project exhibits, and a booth. You can find a summary below.

Your interest in our work is appreciated. We want you to enjoy open source non-profit digital radio and amateur radio to the fullest. How can we help?

Here is how to get involved with what we do:

Here’s a roundup of what we brought to Ham Expo. All of what we do is published as it is created. Our work is free to the general public at no cost.

Ribbit, a new digital text messaging mode for UHF/VHF emergency communications

Presentors: Pierre Deliou W4CKX, Ahmet Inan

Level: General Audience Category: Emergency Communications Time:

PDT: September 18, 2022, 10:00 am UTC: September 18, 2022, 5:00 pm

Ribbit is a novel digital text messaging mode for VHF/UHF communications for recreational and emergency use which radically increases the density of information transmitted by spectrum used. It leverages the computing power of the modern smartphone to increase the capabilities of any Handy Talkie without requiring any additional hardware. Its redundant distributed nature allows it to function even when connectivity to the internet is lost during emergencies. Ribbit is open source and currently in its early stages of development.

Artificial Intelligence and Machine Learning and the Future of Amateur Radio

Level: Intermediate Category: DSP and Software Design, Future of Amateur Radio, SDR Software Defined Radio, Software and Services Time:

Artificial Intelligence and Machine Learning are all over the news, taking over academia, getting billions of dollars of commercial investment, and will change both computer networking and wireless communications in fundamental ways. What does the future of amateur radio look like when radios use machine learning to operate? How does our relationship to the bands change with cognitive radio? Where are we in this transformation? What will happen next?A working group to produce an AI/ML Handbook for Amateur Radio is forming now. Register your interest here: https://forms.gle/4dZsLkmyxCkp8JiF6

Truly Excellent Digital Voice Quality: Opulent Voice

Presentors: Paul Williamson KB5MU

Level: General Audience Category: Digital Voice Mode, DSP and Software Design, Software and Satellites, Space and Satellites Time:

PDT: September 17, 2022, 9:00 am UTC: September 17, 2022, 4:00 pm

Digital voice on amateur radio to date has generally had terrible voice quality, due to both a perception of limited available bandwidth and the convenience (to manufacturers) of repurposing commercial protocols with their older, proprietary, low-bitrate voice codecs. We present and demonstrate a modern digital voice design that can be used on 222 MHz and above with truly excellent voice quality. Source code here: https://github.com/phase4ground/opv-cxx-demod

Haifuraiya – Open Source HEO Satellite Project Proposal

Presentors: Michelle Thompson W5NYV

Level: General Audience Category: Space and Satellites Time:

PDT: September 18, 2022, 9:00 am UTC: September 18, 2022, 4:00 pm

Haifuraiya is an open source highly elliptical orbit amateur satellite project proposal. This presentation will walk through the high-level project proposal. The project features a digital microwave multiplexing transceiver with a failover transponder mode, has an international volunteer team open to community participants, and complies with debris mitigation guidance from the United States Federal Communications Commission.

User Authentication for Amateur Satellites

Presentors: Paul Williamson KB5MU

Level: General Audience Category: DSP and Software Design, Software and Satellites, Space and Satellites Time:

PDT: September 17, 2022, 8:00 am UTC: September 17, 2022, 3:00 pm

After a brief discussion of the reasons why user authentication is needed on an amateur satellite service system, we’ll cover a proposed system to implement reasonably secure user authentication on a P4XT digital multiplexing satellite transponder, within the bounds of the (United States) rules.

We had three project showcases in the Project Gallery

Each Gallery had a Q&A tab, a poster or document, links to any papers, and a link to any associated video presentations.

1) Ribbit, a distributed digital messaging platform

2) Opulent Voice – High Bitrate Digital Voice and Data

3) Open Source Satellite Work is Free of ITAR/EAR

Kumospace Lounge

Thank you to Ham Expo for providing fun and effective Lounges for interaction at the conference. We truly enjoyed visiting with everyone that dropped by! We hope you enjoyed our themed events and the extended Q&A in the Lounges.

Amateur Space Radio Exhibit to host ORI Technical Demos at Ham Expo March 2021

Please visit the Amateur Space Radio exhibit at the upcoming Ham Expo, 12-14 March 2021.

https://www.qsotodayhamexpo.com/

Amateur Space Radio is any amateur radio activity that has to do with space. It could be satellites, ionospheric sounding, ground stations, any AMSAT activity, schools, citizen science, radio astronomy, and more.

Exhibit support website is located at https://amateurspace.radio/

Space Radio is fun and accessible. There is room for people that want to operate satellites. There is room for advanced experimenters improving the technology. There is room for people that buy commercial equipment. There is room for DIY and open source. And, there is room for you!

Saturday’s Space and Satellite Track features eight talks that cover all aspects of Space Radio. How to get started with equipment you already own, an introductory talk that opens up all of the magic of satellite operations, a deep dive into current microwave band digital transponder technology, a history of GEO projects at AMSAT, an explanation of what is required to support an international volunteer team working on FPGA development for amateur satellite work, some very good regulatory news for the United States, how we are engaging students in amateur satellite, and what we need to do about space junk.

All of the talks will be available after Ham Expo, but at the event you will get to interact with the presenters directly, asking them questions, live. Many of these speakers will be at the Amateur Space Radio booth for breakout sessions.

The breakout session schedule includes Getting Started, Roving Operations, JAMSAT, Tech Talk, Tech Demos with Open Research Institute and others, ARDC, Space Weather with TAPR, and an Antenna Session with Kent Britain. We have a couple of open tables and if you want to see something discussed, then please come by and we will set something up.

The Amateur Space Radio exhibit in the Expo doesn’t just have breakout sessions with subject matter experts. It also has nine hours of video content from around the world. These videos include highlight reels, tutorials, and presentations. They cover activity ranging from FM satellite operations to antenna design to advanced propulsion experiments and more. We are playing the world class GNU Radio workshop from Dr. Estevez about decoding satellite transmissions on Sunday with all of the resources needed to participate, linked at the booth.

Our video playlist is available on YouTube from a link at front of the booth. This allows on demand viewing. The schedule for when they will be shown during the Expo is at the booth.

We have two social events this year. Friday night is a custom electronic dance set from John Brier. The recording will also be available through a link at the booth. John Brier is an active satellite operator and educator and is also an electronic dance music musician.

Our second social event is an online scavenger hunt with an Around the World Theme. The event starts at 7pm US Pacific tonight, Saturday, the 13 of March, and will be conducted through Zoom by Watson’s Adventures. If you want a ticket, come to Amateur Space Radio and find the Watson table. First come first serve. If you cannot use your ticket please return it or find someone who can. The adventure will start at 7pm US Pacific time sharp, so make sure to join ahead of time so you won’t be left out. We will close the table when we have given all tickets out.

If you want to learn more about Amateur Space Radio, and stay in touch, please use the Register Interest on our main banner at Ham Expo. We think space is the most exciting part of the amateur radio hobby and we want to hear from you on how to best support it moving forward.

Thank you to Ham Expo and the satellite community for making this exhibit such a success. Please welcome our speakers, and see you at the booth!

Welcome to Ham Expo March 2021
