@ftg I have heard that DMR can be complicated, but needing 4 decades to get DMR working sure seems like a long time!
I mean, first you have to wait for it to be invented...
...I am just being silly. Sorry.
Hey, good that you helped him get DMR working!
I got #DMR working, but only in software, using #DroidStar on Android. With an open-source codec.
Because I was also interested in the #M17 protocol.
I'm looking forward to the day multiple ham radio equipment manufacturers offer HTs and mobiles that allow you to use #m17 the moment you unbox and power on the radio.
I think it'll happen.

@nivex thank you so much for asking.
Here's a page on Opulent Voice, followed by links to the demonstration video from DEFCON30.

The harsh low quality audio of #m17 was a huge deal killer.
Since this demo, we've seen OPV use on a couple of rocket and #satellite projects, and additional protocol layers implemented. Current work is to integrate OPV into the FPGA work for #Haifuraiya
Still quite a pile of stuff to read and make sense off.
I guess the code on github is related or the real Beken provided demo code. As this document seems to talk about functions a lot.
At the very end of the document. There is this mention of filter bypass for digital use.
That might interest the
@m17_project and
@openrtx folks.

And this is what the box is.
It contained two #NiceRF #SA868 #70cm radio modules of the Open Edition variant.
Now I need to make the programmer and dig up their FOSS firmware by @edgetriggered
One step closer to my own homebrew #M17 digital voice radio.

Do you think we've had enough closed, irreproducible, proprietary digital modes contaminating the #hamradio hobby (#ROS, #VARA, #DMR, #YSF, #DSTAR, etc.)? Well, now we've got #LORA for #APRS.
No: ham radio should be based on open, free standards. There are plenty of free, open, well documented digital modes (#FT8, #JS9, #WSPR, #M17, #PSK, #Olivia, #RTTY) in addition to the oldest-ever digital mode (#CW). Please support ways of operation everyone can inspect, modify, or build a radio around.

#M17 incoming. Just moded my TYT MD-UV380. Not tested yet, but the radio is still turning on. So yay!
TNC4 pre-orders start Monday, February 6 at 9AM CST. All the goodness of the TNC3, with USB-C and #M17 support.
Well I've finally had the courage to modify my MD-380 for #M17 use.
Now working on our local digital repeater to support M17.
