业余无线电爱好者(又称“火腿”)自从无线电存在的早期就活跃在相关实验与开发的前沿。在各个无线电频段上,有多种常用的通信模式。 本页面列举了AUR中与业余无线电有关的软件,其中有些可以独立运行,但多数处理数字通信的程序则需要配合无线电硬件或者声卡使用。相关硬件可以购买,也可以自制。

Warning: 按国际条约要求,你必须持有政府发放的执照才能使用业余无线电频率。但这些条约只是约束信号的发射;只接收业余无线电信号或下载相关软件是不违法的。

通用信息

下面的很多程序都需要使用串口(如/dev/ttyS0)与发射器通信。首先,你的用户需要在uucp用户组中。要将一个用户添加到uucp组中,以root身份运行下面的命令:

# gpasswd -a 用户名 uucp

之后注销再重新登录。

软件列表

  • Hamlib — 为无线电硬件和控制程序之间提供了一个通信界面。它只是用于帮助控制电台等硬件,并不是一个能独立使用的程序。
https://sourceforge.net/projects/hamlib/ || hamlib
  • Soundmodem — 由Tom Sailer(HB9JNX/AE4WA)编写,它能将声卡作为一个分组无线电的调制解调器,从而能使用多种AX.25通信模式。波特率最高能达到9600bps, 但也取决于硬件配置和具体用途。Soundmodem可以在串口上作为一个KISS调制解调器或者AX.25网络设备。To use soundmodem as an MKISS network device, the kernel must be re-built with MKISS modules. 该链接中有更多信息:Xastir wiki
以root身份运行soundmodem:
# soundmodem
If you have configured soundmodem as a KISS modem, you will need to change permissions to make it user-readable:
# chmod 666 /dev/soundmodem0

AX.25

AX.25 — 一个广泛应用于分组无线电的数据链路层协议。它既支持有线连接(如keyboard-to-keyboard contacts, access to local bulletin board systems, and DX clusters),也支持无线连接(如APRS)。Linux内核中有对AX.25的原生支持。这里有更多信息:guideAUR中有以下软件可用:

WSJT

WSJT (Weak Signal Communication by K1JT) — offers a rich variety of features, including specific digital protocols optimized for meteor scatter, ionospheric scatter, and EME (moonbounce) at VHF/UHF, as well as HF skywave propagation. WSJT的开发者是诺贝尔物理学奖得主Joe Taylor,无线电呼号为KIJT。The program can decode fraction-of-a-second signals reflected from ionized meteor trails and steady signals 10 dB below the audible threshold.
WSJT is in ongoing, active development by a team of programmers led by K1JT. WSJT (and the related program WSPR) has the option of being configured with

$ ./configure --enable-g95

or

$ ./configure --enable-gfortran

If you build with one and experience problems, edit PKGBUILD to try the other.
WSJT requires access to the serial port; see the note in the Interfacing section above about the uucp group.

WSPR

WSPR (Weak Signal Propagation Reporter, pronounced whisper) — enables the probing of propagation paths on the amateur radio bands using low power transmissions. It was introduced in 2008 by K1JT following the success and widespread adoption of WSJT by the amateur radio community. Stations with Internet access can automatically upload their reception reports to a central database called WSPRnet, which includes a mapping facility

Xastir

Xastir — stands for X Amateur Station and Information Reporting. It works with APRS, an amateur radio-based system for real time tactical digital communications. Xastir is an open-source program that provides full-featured, client-side access to APRS. It is currently in a state of active development.
Xastir is highly flexible and there are a wide variety of ways it can be configured. For example, it can be evaluated without radio hardware if an Internet connection is available. The wiki at xastir.org is very thorough and gives excellent information on its range of capabilities and setup.
An optional speech feature can be enabled with the festival package; you will also need a speaker package such as festival-en or festival-english. If you want this option, festival must be installed on your system before building xastir. Launch festival before the xastir program is started for speech to function properly:

$ festival --server

or you can write a simple script to automate the sequential starting process. There may be problems if other programs such as a media player are accessing sound simultaneously.
The PKGBUILD automatically downloads an 850 kB bundle of .wav files and places them here: /usr/share/xastir/sounds/.
These are audio alarm recordings of a North American English speaker that do not require the presence of festival to render. The audio play command `play' in the configure menu may not work; try `aplay' instead.

数字语音

FreeDV — is a Digital Voice mode for HF radio. It uses the free and open Codec2 voice codec to enable efficient narrow bandwith, low bitrate voice communication ideally suited for shortwave radio contacts. A SSB radio connected to a computer running the FreeDV GUI application are all that is needed to start using the FreeDV mode. FreeDV as well as Codec2 are available to Arch Linux via the AUR system. Both are needed for FreeDV to work!
