Weak Signal Communication SoftwareWSJT-X and MAP65 are open-source programs designed for weak-signal digital communication by amateur radio. Normal usage requires a standard SSB transceiver and a personal computer with soundcard, or the equivalent. SDR-style hardware including the SDR-IQ, Perseus, SoftRock, and FUNcube Dongle is supported by MAP65. All of the programs are available free of charge, licensed under the GNU General Public License. Installation packages for WSJT-X are available for Windows, Linux, and OS X, and MAP65 ais Windows only. For further details about source code and operating systems, see the Program Development page. WSJT-X ("Weak
Signal Communication, by K1JT") offers specific digital
protocols optimized for EME (moonbounce), meteor scatter,
and ionospheric scatter, at VHF/UHF, as well as for LF,
MF, and HF propagation. The program can decode
fraction-of-a-second signals reflected from ionized meteor
trails and steady signals more than 10 dB below the
audible threshold. WSJT-X incorporates nearly all popular
capabilities of the former programs WSJT and WSPR,
while adding comprehensive rig control and many other
features. Check the
WSJT-X
page and links therein for details about modes FT4,
FT8, FST4, FST4S, JT4, JT9, JT65, Q65, MSK144, and
WSPR. MAP65
implements
a wideband receiver for JT65 signals, optimized for
EME on the VHF/UHF bands. It can be used together
with Linrad
(by SM5BSZ) or with direct input from a soundcard or
FUNcube Dongle. The program decodes all JT65 signals
in a passband up to 90 kHz wide, producing a sorted band
map of decoded callsigns. In a dual-polarization
system, MAP65
optimally matches the linear polarization angle of each
signal, thereby eliminating problems with Faraday rotation
and spatial polarization offsets.
