WSJT-X is developed by a team of developer led by Nobel Prize winning physicist Joe Taylor, who has the amateur radio callsign K1JT.

WSJT-X (Weak Signal Communication by K1JT) - offers offers a rich variety of features, including specific digital modes (such as the popular FT-8 and WSPR modes) optimized for weak signal communication, meteor scatter, ionospheric scatter, and EME (moonbounce) at VHF/UHF, as well as HF skywave propagation. The following software is available in the AUR: Please refer to this guide for more information. The Linux kernel includes native support for AX.25 networking. keyboard-to-keyboard contacts, access to local bulletin board systems, and DX clusters) as well as connectionless operation (eg.

xpsk31 - PSK31 using a GUI rendered by GTKĪX.25 - data link layer protocol that is used extensively in packet radio networks.

aprx - lightweight APRS digipeater and i-Gate interface.

fldigi - popular GUI developed by W1HKJ for a variety of digital communication modes.

owx - Command-line utility for programming Wouxun radios using CSV spreadsheets.

quisk - Software defined radio by N2ADR.

linrad - Software defined radio by SM5BSZ.

gMFSK - is a user interface that supports a multitude of digital modes.

Run soundmodem as root: # 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 || soundmodem AUR To use soundmodem as an MKISS network device, the kernel must be re-built with MKISS modules. Soundmodem can be used as a KISS modem on the serial port or as an AX.25 network device. The data rate can be as high as 9600 baud depending on the hardware and application.

Soundmodem - was written by Tom Sailer (HB9JNX/AE4WA) to allow a standard PC soundcard to act as a packet radio modem for use with the various AX.25 communication modes.

for logging, digital modes) and is not a stand-alone application. It is a software layer to facilitate the control of radios and other hardware (eg.

Hamlib - provides an interface between hardware and radio control programs.

To add the user to the uucp group issue the following command as root: This requires that the user belong to the uucp group. Many of the following programs will need to access a serial port to key the transmitter (eg. This only affects you if you have a transmitter and an antenna, receiving amateur radio or just downloading amateur radio software is not illegal. Warning: International treaties require that users of amateur radio frequencies have a government-issued license.
