Делаем аналоговый шлюз в ADN Systems DMR Server

ANALOG <---> DMR GATEWAY

В данной статье описан мост для получения и трансляции (транс кодирования) звука из SVX рефлектора в DMR и обратно. Так же можно подключить радиостанции, образовывая узел или репитер. Подключится к Echolink или FRN сети.

Делаем шлюз с помощью SVXLink-USRP и DVSwitch на ARM платформе как Raspberry Pi и подобных, или VPS, без дорогостоящего AMBE кодека (DV свистка), используя  эмулятор md380-emu

Собственно мост можно настроить не только в DMR и обратно, так же можно транс кодировать и/из в другие моды (YSF, D-STAR, NXDN, P25...).

Ставим SVXLink-USRP:

sudo apt-get update && sudo apt-get upgrade -y

cd
sudo useradd -rG audio,plugdev,dialout svxlink

sudo apt install -y mc zip unzip libcurl4-openssl-dev libjsoncpp-dev g++ cmake make libsigc++-2.0-dev libgsm1-dev libpopt-dev alsa-utils tcl-dev libgcrypt20-dev vorbis-tools curl libcurl4-openssl-dev git rtl-sdr libspeex-dev libasound2-dev libopus-dev librtlsdr-dev

sudo git clone https://github.com/dl1hrc/svxlink.git

cd svxlink/src
sudo git checkout svxlink-usrp

sudo mkdir build

cd build
sudo cmake -DUSE_QT=OFF -DCMAKE_INSTALL_PREFIX=/usr -DSYSCONF_INSTALL_DIR=/etc -DLOCAL_STATE_DIR=/var -DCMAKE_BUILD_TYPE=Release -DWITH_CONTRIB_USRP_LOGIC=ON -DWITH_SYSTEMD=ON -DCPACK_GENERATOR=DEB ..

sudo make

sudo make package

Далее выполним команду:

sudo dpkg -i svxlink-13.12.1.1642.g00cc3916-Linux.deb

Включаем автозагрузку

sudo systemctl enable --now svxlink

Теперь надо установить DVSWITCH по этой инструкции

Далее приступаем к редактированию конфигов по моим образцам. Или можете просто их скачать от сюда, распаковать и скопировать с заменой предварительно подправив их под себя. (см. комментарии в файлах).

nano /etc/svxlink/svxlink.conf

;   When using ASL, this matches the rpt.conf ASL file with a setting like:
;   rxchannel = usrp/127.0.0.1:34001:32001

На этом всё, перезагружаем сервер и проверяем на работоспособность наш мост. Должно появиться ваше подключения на вашем SVX рефлекторе, а также на Украинском ADN DMR сервере

Также по адресу: http://ip вашего сервера появится DashBoard вашего DVSwitch. Возможно он у вас будет не корректно отображаться. Скорее всего это из-за того что на вашем сервере установлен PHP 8.x а ему нужен php не выше 7.4. Проверить версию вашего PHP можно в консоли, командой php -v (это поправимо).
