PEARS WSJT HOMEPAGE
COMPILED BY BARRY ZR2DX
WSJT is a computer program for VHF/UHF communication using state of the art
digital techniques. It can decode fraction-of-a-second signals reflected
from meteor trails, as well as steady signals 10 to 20 dB weaker than those
required for conventional CW. It is freely available to radio amateurs for
non-commercial purposes.
To use the program you will need a computer equipped with a sound card and
running the Microsoft Windows© operating system.
The latest update is WSJT Version 4.7.0. It is able to run simultaneously with the latest version of Spectran, by I2PHD and IK2CZL, which is included in the WSJT distribution. The combination of programs provides an excellent real-time spectral display in addition to all the features of WSJT.
Version 4.7 of WSJT supports four principal operating modes:
FSK441: for
meteor scatter
JT65: for EME and extreme troposcatter
JT6M: for meteor scatter (optimized for 50 MHz)
EME Echo: for measuring your own echoes from the Moon
Earlier program versions also supported a mode called JT44. Like JT65, JT44
was designed for EME and troposcatter.
In addition to these communication modes, WSJT offers a Measure mode for testing Sun noise, etc., and an EME Calculator to help you estimate the strength of your own and other stations’ echoes from the moon.
A detailed description of the program is provided in the online User's Guide and Reference Manual. The manual may be downloaded and printed.

4.5.0 and later is based on code licensed from CodeVector Technologies, LLC,
and protected under United States Patent number 6,634,007.
Further Information. Version 1.0 of WSJT was fully described
in the December 2001 issue of QST, starting on page 36. WSJT Version
2.0 introduced an entirely
new mode with exciting capabilities for communication using signals too
weak to be heard or copied by CW. It is described in QST for June 2002
(p. 81)
and also in CQ VHF (spring 2002 issue, p. 12). Full technical descriptions
of the FSK441 and JT44 modes are provided in Appendix A of the manual.

The Standard Operating procedures for Meteorscatter as promulgated by the
IARU Region 1. These procedures were adopted at the IARU Region 1 Conference
in Miskloc-Tapolca (1978), and later slightly amended at the IARU Region 1
Conference in Noordwijkerhout (1987), Toremolinos (1990) and de Haan (1993).
They have not as yet been amended to cope with WSJT.
