WSJT-X implements communication protocols or вЂњmodesвЂќ called FST4, FST4W, FT4, FT8, JT4, JT9, JT65, Q65, MSK144, and WSPR, as well as one called Echo for detecting and measuring your own radio signals reflected from the Moon. The digital signal processing techniques in WSJT-X make it substantially easier for amateur radio operators to employ esoteric propagation modes, such as high-speed meteor scatter and moonbounce. The program was initially written by Joe Taylor, K1JT with Steve Franke, K9AN, but is now open source and is developed by a small team. WSJT-X is a computer program used for weak-signal radio communication between amateur radio operators, or used by Shortwave Radio Listeners ( SWLers SWL) interested in monitoring the FT8 digital communications between amateur radio operators. The antenna is an off-center fed dipole that is over 200 feet in total length (end-to-end measurement). The output to one port is the input from other port and vice versa.ДЄs mentioned, above, the radio used for the communication of FT8 at the station, NW7US, is an Icom IC-7610 transceiver. Each COM port pair provides two COM ports. + Com0Com: The Null-modem emulator allows you to create an unlimited number of virtual COM port pairs and use any pair to connect one COM port based application to another. + Win4IcomSuite: A full-featured radio controlling program which can remote control rigs, and provide control through virtual communication port-sharing. + Log4OM, Version 2: A full-featured logging program, which integrates well with WSJT-X and JTAlert. + JTAlert: Provides several audio and visual alert types based on decoded Callsigns within WSJT-X. (See below for some background on WSJT-X software.)

+ Just how much human involvement is required to make a full FT8 QSO? Does WSJT-X software run all by itself, with no human control? Is WSJT-X a robot, in the sense that it picks a frequency, then initiates or answers a CQ call automatically, or is it just powerful digital-mode software that still requires human control? + A QSO is defined ( as per common knowledgeвЂ“see below) as the exchange of at least the minimum information needed as set by the requirements of a particular award, or, as is defined by lawвЂ“for instance, a QSO would have at least an exchange of the legal call sign assigned to the radio station and/or control operator, the location of the station making the transmission, and a signal report of some kind about the signal received from the other transmitter at the other end of the QSO. (This writer has other issues with FT8, but not on this pointвЂ“see below)ДЄs you watch the video linked in this article, consider these concepts: They have perhaps formed their anti-FT8 opinion in a vacuum of knowledge. While they pontificate about supposed automated computer communications, many of those holding this position have not installed and configured the software, nor tried communicating with the FT8 digital mode. In other words, FT8, in their opinion, is not real amateur radio. There are amateur radio operators within the amateur radio community who regard the FT8 digital mode (FT8 stands for вЂњ Franke-Taylor design, 8-FSK modulationвЂњ, and refers to the mode created by Joe Taylor, K1JT and Steve Franke, K9AN) as robotic (automatic, automated, and unattended) computer-to-computer communications, and not вЂtrueвЂ™ human communicationsвЂ“thus negating the spirit of ham radio. In this video you see (and hear) NW7US make two-way contacts, or QSOs, with stations from around the country and the world. As can be seen, the 30-Meter band was active at this time of day (0720 UTC, onwardвЂ“local nighttime). The frequency used for the FT8 communication in this video is on or about 10.136 MHz, in the 30-Meter shortwave amateur radio allocation (or, band). While there is no narration in the video, the video provides an opportunity for you to see first-hand how typical FT8 operations are performed. The computer is connected to an Icom IC-7610 radio transceiver, controlled by the software. The software packages demonstrated are installed and operational on a modern personal computer. This video is a front-seat view of the software operation performed at the radio room of amateur radio operator, NW7US, Tomas Hood. Here is a video capture of the reception and transmission of many digital FT8-mode amateur radio high-frequency ( HF Shortwave) communication signals.
