    Hi, ok Where can I send you the files? Email address?

    Thanks, Mauro

    Partially solved, see this topic about svxlink: http://svxlink.996268.n3.nabble.com/Audio-File-Help-td3834.html

    I’ve uploaded my wav file manually to /var/lib/openrepeater/sounds/identification, then reconverted with sox and now it plays fine.

    Anyway the web interface uploader is not working for me…

    About the delay, I guess also the usb audio card affects the result. Now I’m using a cheap generic usb audio dongle with C-MEDIA chipset. In the coming days I’ll experiemnt with different audio cards like the BEHRINGER UCA202 that I already used on rpi for projects related to audio streaming: http://www.music-group.com/Categories/Behringer/Computer-Audio/Audio-Interfaces/UCA202/p/P0484

    I’m also thinking to use the usb card as input and rpi integrated audio as output and see what happens in terms of audio delay, just an idea involving two separate devices for in/out.

    For distortion, also be sure to remove the MIC Boost/AGC option in alsamixer (sudo alsamixer->F5->select the mic boost option->press m->ESC).

    My USB dongle MIC input is driven by the radio line output and the MIC input level is set to about 1-3%.

    Regarding the in/out audio delay, in my case with Rpi3 is around 800ms/1s maximum. It’s acceptable, but sometimes can be annoying, I’m wondering if there is any setting or workaround to decrease that delay as much as possible.

    This is another good idea, see what I’ve found with a quick google search on this topic:
    http://raspi-ups.appspot.com/en/index.jsp

    This project seems to be perfect for this use and it’s chaep.

    Thanks W5BFF for reporting your experience, I’ve executed also a number of hard shut downs with no issues, but of course before to put the repeater in production I would like to have some backup.

    Thanks! Mauro IW3ROW
