 A satellite decoding image software called SATFAX now is available to the public from John Wilson, W4UVV. It originally was written to accommodate the image noise dot saturation problem when the desired 40 khz. receiver bandwidth is not available on the receiver/scanner. SATFAX was designed for the occasional satellite wefax monitor who uses an ICOM R7000, R7100, AOR3000A or other receiver/scanner with a typical bandwidth narrower than 40 khz. that can receive 1691 mhz. or 137 mhz. range polar orbiting and/or geostationary wefax transmissions. The wefax audio output signal is input to the computer soundcard and processed by SATFAX. What makes SATFAX unique is in signal processing the software attempts to compensate for the narrower bandwidth of the receiver/scanner. SATFAX is not freeware. It is available for US$25.00 only. No foreign currency can be accepted. Email W4UVV at < w4uvv@comcast.net > or < w4uvv@amsat.org > for ordering information."
MeteoFax32. It is a French program that is especially adapted to use on computers embarked on board of the boats. An English version of this program will available later. This program provides some information concerning the frequencies and the programs of the stations.
The address of the Meteofax32 site is: http://www.meteofax32.com
HamDream and WinDRM from HB9TLK is for Digital Transmissions of Voice and Data over radio with 2.3 to 2.5 khz bandwidth.
First beta version of atpdec has just been released.
Atpdec is a NOAA POES satellite APT image decoder.
It's an open source program targeted for Unix platforms (in particular Linux). It lacks fancy graphical interface but focus more on image quality. (see http://atpdec.sourceforge.net/gallery.html for some examples
N0ONG WX Sat Kepler Editor is designed to work only with AMSAT (verbose) format elements. Import the kepler file from AMSAT using the Open button. Everything other than the weather satellite elemnts will be removed automatically. Now you can remove specific satellites by pushing the appropriate button. Pressing the Save button will save the edited elements as kepler.dat.
The program was written by Robert Boeckmann and runs on Macintosh OS X and OS9 and is freeware

Aleex Greenland G7JGQ have been devoloping a excellent Satellite tracking program AGSatTrack, and is now available to others.
XAXERO come out with an Internet solution to the Weather Fax for Windows Software for under $90. Please check the XAXERO page www.xaxero.com for more details.
a new version of WXTOIMG from Abstract Technologies New Zealand Limited is out that provides a complete Windows 95/98/ME/2000/NTinterface in a self-installing archive.
The software is being supported under Linux, Windows, BeOS, FreeBSD and AIX versions. a Macintosh version isavailable soon.
A new release of Mscan Meteo Fax now has integrate FAX, NAVTEX and RTTY into a single program called Mscan Meteo Pro and is now available from the Mscan pages
WeatherDecode v1.10WeatherDecode is a program for decoding of AAXX and BBXX (FM-12) Meteo messages
A new free Windows satellite tracker programm called SatScape is now available. Satscape a specialised program that predicts where satellites are at the moment. You have also a World view, Horizon views, tabular list and a keppler update via your Internet connection.
An interesting and simple Satellite Tracker called LE SATELLITE FRANCAIS (LSF)
Alberto Casapa, Italy has written receiver control software for different receivers such as Kenwood R-5000, Kenwood TS-790E, Yaesu FT 847, AOR AR 3000 and AOR AR 800. for more info visit Alberto´s Pages.
WXSat for Windows 3.1/95, decodes the signals in the APT format from NOAA, Meteor, Meteosat and GOES Satellites (AM) with a Soundcard.
WXSat can decode also FM-Fax for decoding facsimile-signals transmitting via shortwave.
WXSat works with the soundcard input so there is no external sampling hardware required. A cable between the receiver and the soundcard input is enough. The program has also a good English documentation.
Oded Regev 4Z5BS from Israel has written a small program called TRACKER that allows the creation of maps that can be combined with images taken from NOAA satellites.
I have test it successfully with NOAA images received with WXSAT and JVComm. With it you can see country borders and sea/surface boundaries.
The program is quite small but it comes with the world map so it is about 3.4 Mb in total.
Here is a example from a NOAA 14 picture decoded with WXSAT and added the country borders from the TRACKER program.
Several replies from test users, Oded send me a corrected versionv1.1 . It should work better now. There is still a known bug regarding fast Pentium computers.
The ORBIT program will not run on fast computers (somewhere around 300Mhz and above). The only way to fix it is running a TSR program that slows the computer in DOS mode. You will probably find such TSR programs here . In the next version Oded will try to add it to the release.
v1.1: Fixed bug in TRACKER.EXE with longitudes in the range 100E-360E (=100E-0E)
Test users should download the upgrade from v1.0 to v1.1 here and copy the new files to the TRACKER directory
Julian Moss wrote a application called SatMon. With this utillity you can recording audio signals from weather satellites as WAV files to decode with WXSAT or other programs.
David J Taylor wrote a decode program called SatSignal
With this program you can demodulate signals from pre-recorded .WAV files. This program produce higher resolution images without the bent verticals resulting from Meteor decode with WXSAT.
David has also excellent satellite tracking software called WXtrack
Les Hamilton wrote a program called PALETTE to optimised the colors from images decoded with WXSAT.
PALETTE is a Windows 3.x/9.x compliant program wich operates on luminance bands within a BMP image produced using WXSAT in conjunction with an image processing program such as Paintshop Pro etc.
Hellschreiber, wich becomes worldwide a renewed interest is a very old mode wich was first introduced 1921 by Rudolf Hell.
The Hellschreiber is an early faximile communication , where only upper case letters were transmitted and received.
Hellschreiber is an asynchronous transfer mode where the signal is discretely coded. This means two things:
The transmitter does not tell the receiver how fast it transmits. It simply sends the message in it's own speed and the receiver must do it's best.
Hellschript is transmitted with either on or off signal. It was hence easy to implement on available radio equipement. One simply connected the transmitter to where the morse key would be. Such signals are very sturdy to radio noise. All unwanted frequencies may be filtered away.
The hellschreiber was invented by Dr. Rudolf Hell in 1929 . It was used by the Germans during WW2 and some receivers was built by the British and Americans to intercept enemy communications.

Les Hamilton, UK has launched a new Satellite tracking program called Footprint.
Footprint is program which displays the positions of an orbiting satellite and its footprint on a map of the Earth, updating its position and footprint every minute.
The program can also provide reference tables of relevant ephemeris, A.O.S. and keplerian element data.
The program reads satellites' orbital elements from keplerian element files in standard NASA 2-line format, specifically filtering out only those satellites belonging to the following classes :
NOAA, USA; Meteor Okean and Resurs, Russia; Sich, Ukraine.
Download your copy of Footprint from Les Hamilton´s Home Page.
FOOTPRINT has now a two-map option. You can change the map to one centred on 180 degrees ( for Australian users ).Also, the time and date routines have been improved.
