Further technical information primarily of interest to programmers is available here. Target dates for candidate releases are as follows:. WSJT-X 2. In contrast, the new MSK protocol replaces the old one from the outset, without backward compatibility.

Parameters i3 and n3 shown in the first column are used in the software to define major and minor bit message types. In the above list, callsigns enclosed in angle brackets e. They will be displayed correctly by receiving stations that have copied the full callsign without brackets in a previous transmissiion. Hash collisions are possible but should be rare, and extremely rare within a particular QSO. When we began hosting HRD, the site we originally obtained our copy of the software from had a notice that the software was authorized for free distribution by its original author Simon Brown, HB9DRV.

As it turns out, that notice was inaccurate. While that was true at one time, the terms the program was licensed under did not grant a permanent license to freely distribute the program forever.

JT4: Formatting and display of averaged and Deep Search decodes has been cleaned up and made consistent with other modes used for EME and extreme weak-signal work on microwave bands. JT Many improvements have been made for averaged and Deep Search decodes, and their display to the user. We now use up to three decoding passes. Pass 3 assumes no drift and does coherent block detection of up to three symbols.
