Related to the md380-emu software, the one at this repository includes an option (-S) needed to run a udp socket server:

Changing TG is like doing a PTT, so if you open multiple TGs in a short time period you can get blocked.
How long do you get blocked for ?
Possibly 24 hours

But if you change your station ID e.g. to 02 or 03 etc that normally gets around the block
I think the block is a hour . All sorted now . What mic did you use with the Raspberry PI 3b ?

With the pi 3 I use a logitech usb headset with mic. With the dk2 (stm32mp157-dk2) wich is the one that I use most of the time, I use Samsung in-ear earphones from an old phone and they work great.

I have tested with USB headsets and also a USB audio card (brand UGREEN) and both were detected as sound cards without installing any additional software.

DMRStation SW runs on a RPi4 with 3.5" LCD touchscreen and USB souncard. ( https://www.youtube.com/watch?v=ZlqMuv9Lb28 )
The SW runs on a RPi0 also but no sound.

Nice!

If pulse audio can run in the pi 0zero there is no apparent reason not to have audio. I will try to get a pi zero for testing.

Ok i got this fixed by doing this .

WARNING **: Error retrieving accessibility bus address: org.freedesktop.DBus.Error.ServiceUnknown: The name org.a11y.Bus was not provided by any .service files

to solve I installed 'at-spi2-core'
Code: Select all

sudo apt-get install at-spi2-core

i found the answer in this thread https://github.com/NixOS/nixpkgs/issues/16327
