FWIW, I thought the voice quality was significantly better than I expected when I was playing with the app earlier this week. Then again, I think I was mentally expecting something only a bit better than 700D (maybe 2020 quality at best) considering that's what I use the most often on HF and all.

In the M17 client, there is a box on the screen right now for an Echo test, so you can hear what you sound like through the network. Here’s a screenshot of the client interface. The system seems to work quite well from all the testing we have been doing so far. As we have been changing

I honestly don't see how that claim could be made at this time, as there is NO radio on the air at this point to demonstrate that.  Perhaps it's a theoretical performance based on the current design, and it would certainly be incredible to see that. Right now, we are ONLY using software

Hi all, Somewhere in the M17 protocol is there a Codec2 mode number? As, my Freebeacon here could put the Codec2 data into a M17 reflector but I'd like to stick to mode 700C data. Alan VK2ZIW On Sun, 25 Oct 2020 10:58:10 +1030, David Rowe wrote > Thanks Walter. I was wondering about this

Thanks Walter. I was wondering about this statement on the M17 page: "M17 uses Codec2, written and developed by David Rowe. Codec2 outperforms existing proprietary and patented (non-free) vocoders currently available." Do you (or others on this list) think Codec 2 at 3200 bits/ outperforms the

Here’s a few notes I sent to someone else earlier today. M17 is a very NEW project with a great deal of traction just recently. https://m17project.org/faq/ has some details about what is happening. This is a completely open source project using David Rowe’s Codec2 for the encoding

Thanks Walter, wow that M17 project is really getting popular. I just took a look at the Codec 2 3200 mode, I recall it was something I knocked up in a few hours - the date is 2012! Does sound pretty good, I hadn't listened to it for a while. Since then I've spent most of my time messing around

Several of us have been working with M17 for the past week, using the Mvoice linux client, and it's working quite well with the reflectors they have in place today. The number of reflectors have increased from 3 early last week to 9 as of this morning, with a couple more that should show up

It is also possible to use one of the existing low-bandwidth text formats on the upper or lower edge of the voice signal. The advantage being that more people could read it. On Fri, Oct 23, 2020, 10:54 PM Al Beard wrote: > Hi all, > > I was looking at the M17 project and noticing their
