Figure 1 - Thumbnail page of recently decoded images You can select from several options to start processing: Select an existing audio file Select what s called a raw image Select Record Standby (waiting for a 2400 Hz carrier) and reception take no noticeable CPU resources and I leave them running all the time. A stumbling block with Linux programs is the sometimes more austere user interface. Still, you will normally never stop the program, so it's not too bad either). (Personally, I do not approve of this method of trying to get the user to register. The most recent few versions display a nag screen which waits for 10 seconds before enabling the rest of the program. (If you use Windows, then just double-click the wxinstnnnn.exe file and installation is automatic, complete with a desktop short-cut icon.) There s a command line version for Linux, which permits execution of all reception and processing from batch files (in fact, it consists of a suite of 5 commandline programs: wxtoimg, wxrec, wxmap, wxproj, and wxbatch, each of which does the task which its name implies).
Copy xwxtoimg to /usr/local/bin where the operating system will find it, and you re set. You can download WXtoImg from: Installing WXtoImg Installing WXtoImg in Linux is easy there s just one executable file. The latter adds several projections, some processing options, and can even automatically create and update web-pages with your images. WXtoImg comes in two forms the standard version which is free, and which is the one I m describing below, and the professional version, for which a low registration fee is required. A case in point is the WXtoImg program, which is available on the Internet, both for Windows and Linux (there s also a MacOS version but it isn t updated as frequently). But generally, programs that are available are of excellent quality, offer many options, and are very reliable(and free, with source code!). Do continue reading - there s a Windows version for the others too! I freely admit that software offerings for Linux are somewhat limited, not entirely unlike the recent problems we have faced in electronic component procurement. Some say I m somewhat biased (or worse) towards Linux, but I feel that somehow this operating system reflects part of the radio amateur spirit. I does most of what has to be done in automated APT reception and processing, and does it very well indeed. 1 John Coppens ON6JC/LW3HAZ - WXtoImg is one of those strange programs that may at first frighten the casual user but offers an impressive performance for its price (free for the limited version).
