They both run under Linux and are open source (GPL). The first is LinWSJT 0.4 which is an implementation of the FSK441 and JT44 data modes for use with Meteor Scatter and EME/Tropo respectively. New with this release is the FSK441 program as well as changes to the JT44 program, although these are not visible to the user. Both programs make use of the sound card in a PC to do the receiving and transmitting, the hard work is done by Digital Signal Processing functions within the program. The only real requirement is that the computer clock is within one second or so of the correct time. Within the package is a Word 2000 document outlining in simple language some of the techniques that are used. The second piece of software is UKW Tools which allows for the plotting of terrain so that radio paths can be investigated. The actual data used for this must be obtained separately over the Internet. This is a minor revision of the previous release and fixes a couple of bugs. Both of these packages can be found on my web pages http://www.qsl.net/g4klx under Software. There you will also find MTrack my satellite tracking program and Baken which visualises European V/U/SHF beacons. Both of these latter two packages have whiskers on. Jonathan HB9DRD/G4KLX
