[Freetel-codec2] Scheduled down time for codec2.org

Amazon says we'll be down in part of a 2 hour window starting on Mon, 13 Jun 2022 00:00:00 and at the end they will reboot the instance. Thanks Bruce ___ Freetel-codec2 mailing list Freetel-codec2@lists.sourceforge.net

Re: [Freetel-codec2] [digitalvoice] Starting an organization for FreeDV/Codec2 development

Strongly agreed. I am hoping that one of those organizations will be agreeable to serving as a largely-hands-off and non-opinionated facilitator to Amateur Radio projects with little more than insistence on Open Source and an ability to receive funds and dispense checks. It may actually help that

[Freetel-codec2] Chris Testa KD2BMH?

Chris Testa KD2BMH dropped off the net a few years ago, and still had some of my equipment worth a few thousand. I don't have a clue why. I don't care that much about the cost. He has kept his license updated and apparently married his girlfriend and is living in El Segundo. Hopefully they are

Re: [Freetel-codec2] Questions about Codec2 embedded performance

Hardware floating point is required. So, your low-power CPU might not be the right choice - I think only the ones with "F" in the part number have hardware floating point. And don't ask anyone to rewrite the code for fixed-point unless you have a lot of money :-) Since OpenRTX has been getting

Switching licenses is possible. There is a publish-for-opposition process, you make a reasonable effort to notify contributors and make public notices, and set a date by which they must oppose. If they oppose, remove their code and replace it. But I'm no fan of you allowing people with

Hi Al and others, The M17 project has affiliated with Open Research Institute, so that they can solicit for grants as an IRS accredited 501 c 3 nonprofit organization. Since ARDC will be granting 5 million dollars a year to amateur radio Open Source projects every year, this is a viable prospect

Re: [Freetel-codec2] interesting, the dudestar app

One strategy would be to treat the m17 STM32 processor as a wireless interface alone, and do the codec processing and user interface in your phone. This would allow you to use the high computation codecs when you couple the m17 and your phone. On Wed, Nov 18, 2020, 5:45 PM Al Beard via

Why don't you make a Raspberry Pi daughter board? It gives people some latitude in choosing how much compute they want, and it's a lot less expensive than most compute solutions you could put together. It provides ethernet, Wi-Fi, lots of USB, lots of undedicated I/O. And they will upgrade faster
