Abraxas3d W5NYV#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.
Open Research Institute#OpulentVoice progress report. Interoperability milestone achieved.
4 February 2026 Opulent Voice Interoperability Progress Report
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.
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.
