ZS WSJT HOMEPAGE
COMPILED BY BARRY ZR2DX
WSJT is the name of a computer program. It stands for Weak Signal communications,
by K1JT. The program currently supports four principal modes: FSK441 is
the mode designed to support communication using very brief pings
from meteor trails in the ionosphere at about 100km height. Such pings are
typically a few dB above the receiver noise and may last from ten to a few
hundred milliseconds. By using these brief pings FSK441 makes 800 to 2200
km QSOs possible in the Amateur 6m and 2m bands.JT6M is also for meteor
scatter, but especially optimized for the 6-meter band; JT44 is for
extremely weak but slowly varying signals such as those found on troposcatter,
ionoscatter, and Earth-Moon-Earth (EME) paths.The EME Echo mode is
for detecting and measuring your own echoes from the moon. The program also
offers a Measure mode for testing Sun noise and the like, and an EME
Calculator to help you estimate the strength of your own and other stations
echoes from the moon.

IARU REGION 1 METEORSCATTER OPERATING PROCEDURES
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.
