#opulentvoice — Public Fediverse posts

#opulentVoice call over the air at 431.35 MHz in San Diego CA.

Moving #OpulentVoice to be over the air in San Diego, CA, USA, and we had a fun driver bug that resulted in a very wrong spectrum.

Software modem (c++) running on a #PlutoSDR receiving an #OpulentVoice signal transmitted from the HDL version in a #LibreSDR.

Big interoperability milestone achieved tonight.

If anyone happens to be at @fosdem 31 Jan - 1 Feb then one of our @OpenResearchIns volunteers will be presenting #OpulentVoice work. Please feel free to introduce yourself to Evariste @f5oeo Wish I could be there in person!

Things are moving very fast for an #opulentVoice ASIC.

This is on track to be the first #opensource #hamradio chip in the world, and will have much better voice quality and user experience than any other digital voice option out there. Radio hardware to follow.

Funding and partners are now in place, despite tariff and supply chain challenges.

It's an honor and privilege to work with a fantastic international team of ORI volunteers.

Frame lock signaling work moving forward fast - we'll talk about it today at @OpenResearchIns weekly meetup.

New sync word successfully received, flywheel style frame synchronization state machine working well so far.

Verification/Validation started. Found an initialization bug that affects only the second frame. Not bad for the first run of upgraded code. Thank you to everyone helping with #OpulentVoice!

Today we test #OpulentVoice human-radio web interface against Web Content Accessibility Guidelines #wcag and write down anything that needs to be changed to make it more #accessible.

This phase will be driven from automated test suites from a variety of sources.

The next phase will be from people evaluating what we've done and letting us know where we need to do better.

Thank you to everyone helping us do ambitious work for #amateurradio !

Major milestone for #OpulentVoice happened yesterday. It's sputtering and coughing a bit, because of all the usual problems with developing a digital radio system, but we have end-to-end microphone to airwaves transmission.

For terrestrial applications, this brings us incredibly close to an HT and really nice repeater (conference) system. That work will continue.

For space, this is a working uplink. Satellite multi rate receiver is next in line for integration.

#amateur #radio

The ARM code for the Pluto SDR that listens for #OpulentVoice frames coming in from the radio-human interface compiled without errors tonight and will be tested early tomorrow morning.

If you saw us at #defcon then you may recall the modem and the human-radio interface were demonstrates separately.

We may have things working end-to-end very soon. Microphone and keyboard to over the air for a full uplink demonstration.

Yesterday for #OpulentVoice: a serious chat-only interface bug was fixed, the uptime clock format was improved, and lab resources for integrating the human-radio interface to the modem were stood up. A very big day at ORI! And, that was just on one project.

The schedule is now out for AMSAT-DL space days and FutureGEO workshop. We are very much looking forward to being a big part of that fundamental shift in #amateur #satellite work. #Ribbit, #RFBitBanger, and more moved forward too.

Quiet day here so I'm thinking about helping out with connecting up the Locutus and Interlocutor projects together.

Locutus is the modem, and Interlocutor is the human-radio interface, for #OpulentVoice.

Each has been demonstrated separately. Time to get the end to end #OpulentVoice system closer to working.

Thank you #amateur #radio community for the support!

Transcriptions now work (and are configurable live) for audio in #OpulentVoice Interlocutor code. Check it out here: https://github.com/OpenResearchInstitute/interlocutor

Transcriptions appear in both web interface and CLI.

Operators guide here: https://github.com/OpenResearchInstitute/interlocutor/blob/main/interlocutor_manual.md

ORI demonstration conference server at 172.236.237.16

Dual stack IPv6/IPv4 added but not fully tested.

Conference server source code and installation and user guide here: https://github.com/OpenResearchInstitute/locus

Transcriptions for #OpulentVoice audio in the web interface not working quite yet, but getting closer!

Human-Radio interface here: https://github.com/OpenResearchInstitute/interlocutor

Conference Server here: https://github.com/OpenResearchInstitute/locus

Intended for UHF and up.

Added Atkinson Hyperlegible font to #OpulentVoice, along with a font size adjuster in the web interface.

Tomorrow we'll get audio transcriptions tested. The transcriptions will be in the message history window, and can be configured on or off in the configuration file. The UI Audio Replay bubble allows you to replay received or sent audio with a play button. When turned on, transcriptions will appear in the UI Audio Replay bubble right below the audio replay button.

#accessibility

Great news - #OpulentVoice successfully flew on University of Puerto Rico's RockSat-X flight today. Transmission received on the ground from the rocket by the student team.

A big Open Source Digital Radio win! ❤️

Full story in the next @OpenResearchIns newsletter.

@OpenResearchIns board meeting starts. Working on #OpulentVoice issues on GitHub.

Local loopback with pseudo random bit sequences is working on the new #fpga based #OpulentVoice implementation. This is a loopback test through just the logic in the FPGA.

The next big step is loopback over the air on the PLUTO.

Tons of great work on #OpulentVoice the past few weeks. It's really an honor to be associated with this team.

Working transceiver in #VHDL for #OpulentVoice. We're adding push to talk and AXI-S interfacing. First draft of integrating it with Analog Devices reference designs went really well.

It's going to be great to demonstrate this live over the air. Thank you to everyone that has helped make this happen!

I guess we're on the right track with #OpulentVoice :D

We are using Sir Martin's implementation of MSK demod/decode/clock recovery for smallsat communications to make an open source design for amateur radio, and he's been a big help, along with several others. Thank you to everyone at UK Surrey!

#amsat #hamradio #opensource

I found a writeup of practical synchronization with MSK, and despite the brevity, it was really refreshing to see. It's of course by a Ham.

The #opulentvoice team will use this and other resources to make an accessible and fully explained design for modern #hamradio communications.

Thank you to all that support this work.

Next up for #opulentvoice is clock recovery.

More progress from the digital down converter for #OpulentVoice.

This is an #opensource #digital #radio design and implementation for #communications #satellites and #terrestrial systems. As much as possible is done on an #fpga.
