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

1
2
3
4
5
6
7
8
9
sudo apt-get install git
sudo apt-get install gcc
sudo apt-get install g++
sudo apt-get install make
sudo apt-get install cmake
sudo apt-get install libasound2-dev
sudo apt-get install libudev-dev
sudo apt-get install libavahi-client-dev
sudo apt-get install rtl-sdr

然后是Direwolf的前置Hamlib

1
2
3
4
5
6
git clone https://github.com/Hamlib/Hamlib.git
cd Hamlib
./bootstrap
./configure
make
sudo make install

和主角Direwolf

cd ~
git clone https://www.github.com/wb2osz/direwolf
cd direwolf
git checkout dev
mkdir build && cd build
cmake ..
make -j4
sudo make install
make install-conf

接下来需要建立配置文件

nano sdr.conf

5
ADEVICE null null
CHANNEL 0
MYCALL XX2XXX #修改成呼号+SSID
IGSERVER asia.aprs2.net #一般无需修改
IGLOGIN XX2XXX 12345 #输入你的呼号和密码

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

1
rtl_fm -f 144.64M -s 24000 -g 48 - | direwolf -c /sdr.conf -r 24000 -D 1 -
