在2024年的今天，搭建iGate早就不用像十多年前手动焊接一个TNC电路加上老旧的APRS4R了，只需一个廉价的SDR即可实现
首先我们需要安装一堆的库
sudo apt-get <span class="hljs-keyword">install</span> git
sudo apt-<span class="hljs-keyword">get</span> <span class="hljs-keyword">install</span> gcc
sudo apt-<span class="hljs-keyword">get</span> <span class="hljs-keyword">install</span> g++
sudo apt-<span class="hljs-keyword">get</span> <span class="hljs-keyword">install</span> make
sudo apt-<span class="hljs-keyword">get</span> <span class="hljs-keyword">install</span> cmake
sudo apt-<span class="hljs-keyword">get</span> <span class="hljs-keyword">install</span> libasound2-dev
sudo apt-<span class="hljs-keyword">get</span> <span class="hljs-keyword">install</span> libudev-dev
sudo apt-<span class="hljs-keyword">get</span> <span class="hljs-keyword">install</span> libavahi-<span class="hljs-keyword">client</span>-dev
sudo apt-<span class="hljs-keyword">get</span> <span class="hljs-keyword">install</span> rtl-sdr
然后是Direwolf的前置Hamlib
git clone http<span class="hljs-variable">s:</span>//github.<span class="hljs-keyword">com</span>/Hamlib/Hamlib.git
<span class="hljs-keyword">cd</span> Hamlib
./bootstrap
./configure
<span class="hljs-keyword">make</span>
sudo <span class="hljs-keyword">make</span> install
和主角Direwolf
<span class="hljs-keyword">cd</span> ~
git clone http<span class="hljs-variable">s:</span>//www.github.<span class="hljs-keyword">com</span>/wb2osz/direwolf
<span class="hljs-keyword">cd</span> direwolf
git checkout dev
<span class="hljs-built_in">mkdir</span> build && <span class="hljs-keyword">cd</span> build
cmake ..
<span class="hljs-keyword">make</span> -j4
sudo <span class="hljs-keyword">make</span> install
<span class="hljs-keyword">make</span> install-<span class="hljs-keyword">conf</span>
接下来需要建立配置文件
nano sdr.conf
ADEVICE <span class="hljs-literal">null</span> <span class="hljs-literal">null</span>
CHANNEL <span class="hljs-number">0</span>
MYCALL XXXX <span class="hljs-meta">#修改成呼号+SSID</span>
IGSERVER asia.aprs2.net <span class="hljs-meta">#一般无需修改</span>
IGLOGIN XXXX <span class="hljs-number">12345</span> <span class="hljs-meta">#输入你的呼号和密码</span>
上方的密码只是一个算法，可以参考lilmatt/callpass-js
最后，通过以下代码运行
rtl_fm -f <span class="hljs-number">144.64</span>M -s <span class="hljs-number">24000</span> -g <span class="hljs-number">48</span> - | direwolf -c /sdr.conf -r <span class="hljs-number">24000</span> -D <span class="hljs-number">1</span> -
我们还可以把它设置成开机自动运行 把上述的运行命令复制到exit 0前即可
sudo nano /etc/rc.<span class="hljs-keyword">local</span>
