The bursts of signal created by such trails are commonly referred to as "pings", due to their characteristic sound. : 1 FSK441 įSK441, introduced in 2001 as the first communications mode included with WSJT, is designed to support communication using streaks of radio-reflecting ions created in the ionosphere by the trails of meteors entering the Earth's atmosphere. : 17 Two other modes, WSPR and Echo are included for measuring propagation and testing moon bounce echo. Some modes have derived submodes with larger tone spacing. : 6 WSJT-X 1.8 additionally implements the "slow" JT9, FT8, and QRA64. As of WSJT10, supported fast modes are JTMS, FSK441, ISCAT, and JT6M, and the slow modes are JT65 and JT4. While fast modes send character-by-character without error correction, the slow modes aim to optimize for minimal QRO (high-power) use. WSJT's communication modes can be divided into fast and slow modes.

The software carries a general emphasis on weak-signal operation and advanced DSP techniques however, the communication modes rely upon different ionospheric propagation modes and may be used on many different bands. As of May 2018, the latest WSJT version is WSJT10. This backwards-incompatibility includes JT64A, such that the preview release of JT64A in WSJT7 cannot communicate with the stable release of JT64A in WSJT8. As of version 8.0 (referred to as colloquially as WSJT8) the available modes changed completely such that WSJT8 now offers 5 different modes (JTMS, ISCAT, JT64A, JT8, and Echo) - none of which are back-compatible with WSJT7 or earlier releases. WSJT versions up through 7.06 r1933 (referred to as colloquially as WSJT7) and earlier were aggregations of previous versions, and as such WSJT7 contained 16 different modes (FSK441, JT6M, JT65 variants A - C, JT2, JT4 variants A - G, WSPR, and a preview of JT64A). Currently, the program is written in Python and C, with several utilities written in Fortran. Although Joe Taylor was the original developer (and still acts as maintainer), several programmers are currently involved in writing the software. This licensing change required substantial rewrites and took several months to complete. Since 2005, the software has been released as open source software under the GNU General Public License. Communication modes have been both added and removed from the software over the course of its development. All colors can be customized via the stylesheet or editing the wfview preference file.WSJT was originally released in 2001 and has undergone several major revisions. The user may select between the current desktop theme, an included “dark” theme (qdarkstylesheet), or a user-specified qt stylesheet. Many of Icom’s transceivers from the last 20 years will work to some degree with wfview, and we are always adding more. Even though our target platform consists of modern-era transceivers, wfview’s command dictionary is focused on commands with the most compatibility. Wfview has been developed with an eye towards compatibility. The server can be a humble Raspberry Pi or a normal desktop computer. On the IC-7300 (and other non-network rigs), wfview can serve as a USB to Ethernet “bridge”, connecting the 7300 to the network for remote control and live streaming full-duplex audio using another instance of wfview on a remote computer.

Special care was taken in the creation of the network code for very low latency audio - ideal for general QSOs as well as time-sensitive modes such as FT8 and JT65. On rigs with built-in network interfaces (such as the IC-705, IC-7610, IC-7850, IC-R8600, and IC-9700), live audio streaming is available for both receive and transmit. Wfview provides the user with controls that may be comfortably operated from a keyboard, mouse, or touch screen interface.
