Inner Circle Newsletter: Summer 2024

A Sizzling Summer Summary prepared just for you!

Read on for highlights from all our technical and regulatory open source digital radio work. ORI’s work directly benefits amateur radio, provides educational and professional development opportunities for people all over the world, and puts ethics and good governance first.

Opulent Voice Flying High

Opulent Voice is an open source high bitrate digital voice (and data) protocol. It’s what we are using for our native digital uplink protocol for ORI’s broadband microwave digital satellite transponder project. Opulent Voice has excellent voice quality, putting it in a completely different category than low bitrate digital communications products such as D-Star, Yaesu System Fusion, and DMR.

Opulent voice switches between high resolution voice and data without requiring the operator to switch to a separate packet mode. Opulent voice also handles keyboard chat and digital file transmission. Seamless integration of different data types, using modern digital communication techniques, differentiates Opulent Voice from any other amateur radio protocol.

Opulent Voice will fly on the University of Puerto Rico’s RockSat-X launch on 13 August 2024. It’s been a very positive experience working with the students and faculty at the University.

An implementation on FPGA for the PLUTO SDR is well underway, with a active international team delivering quality results. This implementation will not only turn your PLUTO SDR into an Opulent Voice transceiver, but it will have remote operation functionality.

Hear what Opulent Voice sounds like by following the links in an earlier update at https://www.openresearch.institute/2022/07/30/opulent-voice-digital-voice-and-data-protocol-update/

We’ve come quite a long way in less than two years! The FPGA implementation upgrades the modulation from 4-ary frequency shift keying to minimum shift keying, and increases forward error correction performance and flexibility.

HAMCON:ZION 2024 is This Week!

Please visit us at HAMCON:ZION 2024 this weekend, 12-13 July 2024 in St. George, Utah, USA.

The event website is https://www.hamconzion.com/

ORI will have a club booth at the event. We opened our space to QRZ.com (https://www.qrz.com/) and Deep Space Exploration Society (https://dses.science/). This combined exhibit is a one-stop shop for the best in community, technical, and citizen science amateur radio activity.

We have a volunteer presenting on Artificial Intelligence and Machine Learning in Amateur Radio. The talk opens with a brief summary of the history of our relationship with created intelligence and then explores case studies of the use of artificial intelligence and machine learning in amateur radio. Talk is 1pm on Friday in Entrada B.

Open Research Institute at DEFCON32

We will present an Open Source Showcase at DEFCON in the Radio Frequency Village 12-13 August 2024, with accessible exhibits and demonstrations. Here is the list of scheduled project demonstrations.

Regulatory Efforts: ORI works hard for open source digital radio work and moves technology from proprietary and controlled to open and free in intelligent and mutually beneficial ways. Our work on ITAR, EAR, Debris Mitigation, AI/ML, and Synthetic Aperture Radar will be presented and explained. Find out more at https://github.com/OpenResearchInstitute/documents/tree/master/Regulatory

Ribbit: this open source communications protocol uses the highest performance error correction and modern techniques to turn any analog radio into a digital text terminal. No wires, no extra equipment.. Learn how to use this communications system and get involved in building a truly innovative open source tactical radio service. Find out more at https://www.ribbitradio.org

Satellite: ORI has the world’s first and only open source HEO/GEO communications satellite project. All working parts of the transponder project will be demonstrated, from Opulent Voice to antenna designs.

The Dumbbell antenna: We have an HF antenna design based on a highly effective inductive loading technique first written about in 1958. Learn about this antenna and find out how to make your own. Repository can be found at https://github.com/OpenResearchInstitute/dumbbell

RFBitBanger: an HF QRP system and novel digital protocol called SCAMP. Kit information and updates will be available. Get your Batch 2 kit today at https://www.ebay.com/itm/364783754396

Radar: Our regulatory and technical work in synthetic aperture radar will be demonstrated. One of our volunteers will be giving a talk about open source synthetic aperture radar in the RF Village speakers track. Here is the abstract.

Synthetic Aperture Radar (SAR) is one of the most useful and interesting techniques in radar, providing high resolution radar satellite images from relatively small satellites. SAR is not limited by the time of day or by atmospheric conditions. It complements satellite photography and other remote sensing techniques, revealing activity on the Earth that would otherwise be hidden. How does the magic happen? This talk will explain the basics of SAR in an accessible and friendly way. That’s the good news.

The bad news? SAR is controlled by ITAR, the International Traffic in Arms Regulations, and is listed in the USML, the United States Munitions List. ITAR regulates the export of defense articles and services and is administered by the US State Department. This includes both products and services as well as technical data. Such as, catalogs of high resolution radar imagary. The articles and services regulated by ITAR are identified in the USML. If ITAR doesn’t get you, then EAR just might. The Export Administration Regulations (EAR) are administered by the US Commerce Department, and items are listed on a Commerce Control List (CCL). Commercial products and services and dual-use items that are not subject to ITAR could be regulated by EAR. Even if you are free of ITAR and EAR, you may still be regulated by yet another agency, such as the FCC.

Regulation of SAR chills commercial activity, creating costly and time-consuming burdens. But why does any of this matter to signals hackers? Because technology has overtaken the rules, and devices used by enthusiasts, researchers, students, and hackers are increasingly likely to have enough capability to fall into export-controlled categories. The penalties are harsh. Fear of running afoul of ITAR is enough to stop a promising open source project in its tracks.

Is there a way forward? Yes. ITAR has a public domain carve out. Information that is published and that is generally accessible or available to the public is excluded from control as ITAR technical data. That’s great in theory, but how can we increase our confidence that we are interpreting these rules correctly? How can we use and build upon these rules, so that our community can learn and practice modern radio techniques with reduced fear and risk? Can we contribute towards regulatory relief when it comes to SAR? We will describe the process, report on the progress, and enumerate the challenges and roadblocks.

RFBitBanger Batch 2 Kits Available

Kits are available at our eBay store at this link https://www.ebay.com/itm/364783754396

Be a part of the future with a prototype Batch 2 kit build of the RFBitBanger, a low-power high-frequency digital radio by Dr. Daniel Marks KW4TI. Presented by Open Research Institute, this kit is designed to produce 4 watts of power and opens up a new digital protocol called SCAMP.

SCAMP Is now available in FLDigi!

Source code and extensive instructions can be found at https://github.com/profdc9/fldigi

Your donation in exchange for this kit directly enables the further development of an innovative Class E amplifier based radio design. It has a display, button menu navigation, and keyboard connection for keyboard modes and keyboard-enabled navigation. This radio can be taken portable or used in a case. If you have a 3d printer, then Dr. Marks has a design ready for you to print in the repository linked below.

  • Built-in digital modes: CW, RTTY, SCAMP (FSK and OOK, multiple speeds)
  • Key jack supports straight keys and iambic paddles
  • Open Source hardware and firmware, Arduino UNO compatible https://github.com/profdc9/RFBitBanger
  • External sound-card FSK digital modes supported (including FT4/FT8)
  • Experimental SSB support
  • Serial port support (2400 baud) for send and receive in keyboard modes

SCAMP is a new protocol that allows keyboard-to-keyboard contacts with a digital protocol that has excellent connection performance. See Dr. Marks presentation about RFBitBanger at QSO Today Academy in September 2023 to learn more about SCAMP and the RFBitBanger project. Link below:

All surface mount parts on the main board are pre-installed at the factory. All the through-hole parts you need to complete the radio are provided for you to solder yourself.

Builder’s notes and photos of all the components to help you identify and install them can be found here:

https://github.com/OpenResearchInstitute/RFBitBanger-kit/tree/main/batch2

If you don’t know how to wind toroids or solder surface mount capacitors, this is an excellent kit to learn on. There are just six toroids on the main board, and two on each band pass filter board. You can build just one band pass filter board and operate on a single band, or you can build an assortment. We provide 12 filter boards, enough toroids to build any 9 filters, and a supply of capacitors that will let you build those 9 filters for 9 different HF ham bands. These capacitors are size 1206, which is the largest common size for SMT capacitors and the easiest to solder manually. All you’ll need is a pair of tweezers and your regular soldering iron and solder. We provide detailed instructions on winding the toroids and soldering the capacitors. You get spare filter boards to experiment with.

Friendly Support is provided through a dedicated Open Research Institute Slack channel.

HamCation 2022 Report

HamCation 2022 Report

Paul Williamson (Remote Labs), Douglas Quagliana (P4DX), Michelle Thompson (ORI), Ed Wilson (M17), and Steve Miller (M17) represented the breadth of projects from Open Research Institute at HamCation 2022.

ORI’s “Tonight’s The Night: SDRs are HOT” booth made its first appearance in nearly two years. Available at the booth were stickers, pins, patches, shirts, consulting, and project updates. ORI’s “extra chair” seating area was appreciated by volunteers and visitors alike. Booth visitors heard about the successful DVB-S2X modem work from ORI and progress on the end-to-end demo of the entire satellite transponder chain. At Open Research Institute, it doesn’t work until it works over the air. Due to the efforts of a truly wonderful international open source team, the custom FPGA code is coming together very well, and Remote Labs continues to evolve. The Phase 4 Digital Multiplexing Transceiver project is on budget, on track, and highly likely to succeed. The return on investment is high. The team isn’t anywhere near done innovating, publishing, and enabling high-tech space aand terrestrial amateur radio work. If you want to be a part of this, or just follow along, visit https://openresearch.institute, go to “Getting Started”, and sign up for the Phase 4 Ground mailing list. This is “home base” for announcements from ORI.

Right beside ORI’s booth was the “future of amateur radio”, the M17 Project. Ed and Steve from M17 brought working hardware, firmware updates, and also demonstrated several different software implementations throughout the weekend. M17 held their weekly net on Friday live from the booth, gave away stickers, magnets, and pins, and captured the hearts of all who visited. You can get involved with this project at https://m17project.org

AmbaSat re-spin was a frequent topic of conversation. The five AmbaSat boards from ORI, which operate at 70cm, have been distributed to the firmware team, and they have begun development and are seeing success in university and hobbyist labs. The goal is to create a compelling application, put the hardware on a sounding rocket, apply for a launch license, and send this project to space in a way that makes the amateur community proud. While “AmbaSat Inspired Sensors” is ORI’s smallest received grant, it has by far the highest capability return on investment of any ORI project.

ORI and M17 booths were located in the North Hall. While the other buildings are larger and many consider them to be higher profile, booths in the North building are what you must walk by to get to the Information Booth and Prize Booth. Since the vast majority of participants visit this part of the show, it is, in our humble opinion, the best possible location.

Michelle Thompson (W5NYV) presented about Digital Communications Technology at the ARRL Expo Technology Track held on Thursday at a conference center near Seaworld. There were four tracks of presentations at the Expo: Contesting, Handbook, Technology, and Emergency Communications.

Michelle reported a positive, enthusiastic, and engaged audience for her ARRL Technology Track talk, and has high hopes that ARRL will continue doing events like this moving forward. She discussed ORI’s Polar Code initiative, successful regulatory and legal work, why open source LDPC work is so important to amateur radio, the four fundamental components to digital communications, and why the M17 protocol was selected as ORI’s satellite uplink protocol for the P4DX transponder project. Michelle invited M17 principals to speak about their work, and opened the floor for questions and comments from the many highly competent and curious technical hams that were in attendance. Subjects covered ranged from asynchronous computing to concatenated coding. The rumors about toilet paper being a fundamentally important part of this presentation are entirely true.

ORI organized a Friday forum track for Clearspan Tent #1 that ran from 11:15am until closing. HamCation was extremely generous in giving us time to present work from a wide variety of people. Here’s our lineup for 2022.

11:15 am
Understanding and Changing Amateur Radio Regulation / Open Source Digital HTs are Real! by Bruce Perens (K6BP)

12:30 pm TAPR – TangerineSDR Update, or How to build an SDR without any parts by

Scotty Cowling (WA2DFI)

1:45 pm M17 Project by Ed Wilson, Steve Miller (N2XDD, KC1AWV)

3:00 pm GNU Radio work at ORI / FreeDV HF Voice Update 2022 by Douglas Quagliana, Mel Whitten (KA2UPW, K0PFX)

3:00 pm Society of Amateur Radio Astronomy SARA by Tom Crowley (KT4XN)

At both the Expo and HamCation, ARRL set the pace this year for satellite talks and satellite demonstrations, with a video (please see https://www.youtube.com/watch?v=fhyUbC_o1JM&ab_channel=ARRLHQ) providing practical examples of amateur satellite operations. Patrick Stoddard (WD9EWK) gave a tutorial on satellite operations at the ARRL Expo in the Handbook Track. Amateur satellite was very well supported from ARRL this year, and we have heard this will continue to strengthen going forward.

With some optimism, ORI looks forward to returning to in-person events. The next planned in-person event is DEFCON (https://defcon.org/). Last year, DEFCON was held in person. Proof of vaccination was required. Masks were required. It was a highly successful and enjoyable event. This year, for 2022, ORI will be represented in DEFCON villages and activities. We are looking at applying for M17 to be part of Demo Labs, multiple radio links between villages to demonstrate a wide variety of technology, and presentations about the R&D that we do.

If you would like to be a part of this, and we do need you, then please join the Slack channel for DEFCON planning. Quite a bit of work is underway already. The goal for DEFCON 2022 is over the air demonstrations, outreach, fun, swag, and supporting our friends at all the villages we’ve been involved with over the years.

DEFCON is run very differently from traditional amateur radio conventions. The most significant practical difference is that DEFCON has a written code of conduct, and those written community standards and policies are enforced. It has a very diverse and very interdisciplinary attendance. Unlike many technical or hobby conferences, participation in the DEFCON community is possible year-round through participation in local groups that meet monthly.

DEFCON is a very large event, with attendance of over 30,000.

DEFCON is devoted to a very broad spectrum of experimental, commercial, and open source work. Participation by the government, industrial, information security, hacker, hobbyist, and scientific communities has steadily grown over the past 30 years.

The next virtual event for Open Research Institute is Ham Expo, 12-13 March 2022. Andre Suoto will have an excellent talk about our open source LDPC encoder for FPGAs and ASICs. This is in the main track. We will have a wide variety of work and projects represented at our booth, which is in the vendor hall. Open Research Institute is a non-profit sponsor of Ham Expo. We’ll have friendly and accessible “office hours” during the event.

Video Report – Trans-Ionospheric Badge Update

https://youtu.be/TgJ7m0OETMw

Badge report! Brag Tape, Radio Peripheral update, and our ESP32 development board. It’s from hacker boxes and has a TFT display, programmable RGB LEDs, an SD card for storage, up down left right select user interface input, and some circuitry for charging a lithium ion battery. It’s a good platform for building up the executive function code for Phase 4 Ground radios.

What do we have working?

A high resolution display, SD card access, and bluetooth advertising that sends commands to the trans ionospheric badge.

ESP32 development can be done with the Arduino IDE, but this is very limited and hogs memory. For Phase 4 Ground we use the ESP IDF. This means command line, but Visual Studio Code works with some setup. This gives you context colors and build and run functions.

We highly recommend the ESP32 check it out at the links below. Our next report will be about multicast IP SDR work. See you then!

Open Research Institute at DEFCON 26

Amateur Radio and open source Amateur Satellite activities at this past week’s DEFCONwere very successful.

Multiple talks across the somewhat daunting schedule provided plenty of opportunities to hear about amateur radio, open source satellites, modulation and coding, and ground station work. Phase 4 Ground had an opportunity to present at Cyberspectrum, and then helped host a Q&A the following day.

Open Research Institute had a booth in the WiFi Village Friday-Sunday. Services provided were the DEFCON ham radio license exam information/encouragement, SatNOGS information/handouts/stickers, Libre Space Foundation information/handouts/stickers, GNU Radio demonstrations and quick tutorials, FaradayRF information/handouts, SDR demonstrations, Trans-Ionospheric badges, Phase 4 Ground updates/recruitment/promotion, and more.

The landscape of amateur radio in space is diverse, interesting, and active. The audience at DEFCON is enthusiastic, positive, technical, and generally unafraid to build things and try stuff.

The Amateur Radio Relay League (ARRL) was there this year, and they are thinking about coming to GNU Radio Conference as well.

We met several university researchers and put them in touch with the right support networks to get their cubesats “off the ground”.

It’s hard work to be part of a event as large, loud, and busy as DEFCON. The attendance was estimated at 27,500 by Sunday. However, it’s very much worth it! It was great to meet so many people in person for the first time that we’ve gotten to know through electronic means.

We are solidly in the black on Trans-Ionospheric badge sales and are well on our way to funding the development board for Phase 4 Ground radios. Support and information here: https://www.openresearch.institute/badge/

We’ll be selling them online shortly. All proceeds go directly to support the non-profit ORI, and specifically for Phase 4 Ground project.

Next up: finding out how to improve representation for amateur radio on interplanetary missions from NASA. We’ll be at the Interplanetary Cubesat Workshop this week at Goddard Space Flight Center. We’ll have a poster session on open source satellite and ground station work, specifically allowed under ITAR 120.11.

Thank you to everyone that helped make this trip rewarding and fun with the encouragement, support, and materials.
