WSPR (pronounced
"whisper") stands for "Weak Signal Propagation Reporter." This
program implements transmitting and receiving for a
digital soundcard mode called "MEPT_JT", an acronym for "Manned
Experimental Propagation Tests, by K1JT". This is the initial
release of a GUI-based version of the program. Screen shot. Click here to download WSPR. Then run the resulting executable to install the program. A full manual for WSPR has not yet been written, but a Quick Start guide is available. Program changes since veraion 0.5 are described in the Changelog. A basic description of the WSPR protocol can be found at physics.princeton.edu/pulsar/K1JT/WSPR_Announcement.TXT . Please send feedback on WSPR and its use to k1jt at arrl dot net. 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 ionized meteor trails, as well as steady signals more than 10 dB weaker than those required for conventional CW. One of its operating modes, JT65, is particularly optimized for amateur EME (Earth-Moon-Earth) communications. WSJT is open source software and is licensed under the GNU General Public License. It has an active development group: for details see http://developer.berlios.de/projects/wsjt/. MAP65 is a new (July
2007) computer program designed to provide the "back end" of a
semi-automated, wideband, polarization-matching receiver for JT65
signals. In works together with Linrad (by SM5BSZ) and suitable
RF hardware to receive and decode all detectable JT65 signals in a 90
kHz passband. MAP65 runs under Windows or Linux. Its
principal intended application is EME or "moonbounce" on the amateur
VHF and UHF bands. A MAP65 status
report is available, as well as a MAP65
Quick Start Guide for users who who wish to participate in beta
testing. Click here to download
the installation file for MAP65. A paper on MAP65 has been placed
on the Documentation page. To use WSJT you will
need a computer equipped with a sound card and running the
Microsoft Windows,
Linux, or FreeBSD
operating system. It should also run on Macintosh OS X,
but this has not yet been confirmed. Volunteers for this task are
welcome! To use MAP65 you need a functioning Linrad system, a dual-polarization antenna, and a second computer with at least 1.4 GHz CPU and 1 GB memory. The current
version of WSJT is version 5.9.7. Changes
from earlier versions are described here.
You
can obtain the program from the
download page (link at left). A new WSJT6
User's Guide and Reference Manual is also available, and
translations into many other languages can be found on the Documentation page. A Windows-based
WSJT
simulator
called SimJT (version
0.9.5) is also available. You can use this program to
test
performance of the JT65 modes of WSJT, and to compare them with
CW. Be sure to read the SimJT User's
Guide, included with the
distribution on the download page. A number of amateurs have volunteered to make CD-ROMs of the WSJT installation
and tutorial files available at very low cost. To find a
volunteer in your region, click here
and then send an email to enquire. If you would like to help with future development
of WSJT, or perhaps to contribute in other ways such as by translating
the WSJT6
User's Guide into another language, please send me email (k1jt
at arrl dot net). Translations into French, German, Italian,
Japanese, Polish, Portuguese, Russian, Serbian, and Spanish are now
available
on the
Documentation
page. We (the WSJT developers) hope you will enjoy using WSJT. -- Joe Taylor, K1JT |
