Changes to the JT65 Deep Search decoder have made it slightly more + sensitive, on average. More importantly, the number of false + decodes has been dramatically reduced. JT65 decoding can be as + much as 3 times faster than before. For these reasons alone, you + should be sure to upgrade if you use JT65. + +2. A more useful menu of JT65 decoding options is provided. You may + now select "No Deep Search", "Normal Deep Search", "Aggressive Deep + Search", or "Include Average in Aggressive Deep Search". + +3. The two end-of-line numbers (formerly displayed only if Aggressive + was checked) are now always displayed in JT65 mode. The first + number is 1 if the Koetter-Vardy decoder succeeded, 0 otherwise. + The second number is the confidence level of the Deep Search + decoding (if enabled) on a 0 to 10 scale. + +4. The JT65 AFC function has been rewritten. Drifting signals + (including Doppler-induced drifts at 1296 MHz) will usually decode + better with AFC turned on. + +5. Mode JT65C, which is used primarily at 1296 MHz, has been improved + in several ways. Synchronizing is better by about 1 "sync" unit, + and signal strengths are measured more reliably. Decoding of + shorthand messages is improved. + +6. When compiled for Linux and FreeBSD (see note below), WSJT now + allows use of parallel as well as serial ports for T/R control. + +7. Wave files are now saved correctly in Linux and FreeBSD versions. + +8. Support has been added for extra-long callsigns such as + VU4AN/VU3RYF. The full augmented callsign must be no longer than + 12 characters. Enter the special add-on DXCC prefix or callsign + (in this case, VU4AN) on the Setup | Options page. + +9. If the "Grid" box on main WSJT window is blank, displayed values of + Doppler and df/dt will be those of your own echoes. + +10. If the ToRadio box is blank, "Mon_" (rather than "_" is now used + as the naming prefix for recorded wave files. + +11. The birdie-killing "Zap" feature has been changed so that if + Freeze is ON, nothing is zapped within Tol of the Freeze DF. In + addition, the Zap behavior no longer depends on previous decoding + history. + +12. Bug fix: previously, if Freeze had been checked while operating in + another mode, Zap no longer worked correctly in FSK441 mode. This + has been fixed. + +13. The selection of data for mouse-picked decodes in JT6M mode has + been corrected. (In recent versions it was necessary to click a + few seconds to the right of a signal enhancement.) + +14. The logic that limits search for JT6M synchronization to a range + of frequencies (+/- Tol around FreezeDF) has been corrected. A + small green tick at the left edge of the main graphical area + indicates the FreezeDF frequency. The FreezeDF value is also + displayed digitally in the status bar. You can change FreezeDF + with the left/right keyboard arrows. Default settings for JT6M are + now Tol=200, Freeze On, MouseDF=0. + +15. If mouse-picked decoding was invoked, all wave files were + previously saved even if "Save none" was selected on the menu. + This has been fixed. + +16. On your first start-up with version 5.9.5, be sure to re-enter + your correct PTT port number on the Setup | Options page. Under + Linux or FreeBSD, enter the appropriate device name, for example + /dev/ttyS0. + +Special note to Linux and FreeBSD users +--------------------------------------- + +WSJT is now being used by a number of people on Linux or FreeBSD +systems. Appearance and operational behavior is essentially identical +to the Windows version. At present you must compile the yourself for +Linix or FreeBSD. Instructions are available, and others who have +succeeded will help you if help is needed. This is not necessarily a +trivial task, however. + +Packaged versions of WSJT for specific *nix distributions may be +provided if there is sufficient demand. + +For more information on WSJT for Linux and FreeBSD, or if you want to +try compiling the program for Mac OS/X, contact the WSJT development +team at wsjt-devel@lists.berlios.de. + +WSJT is Open Source software. The source code and related materials +can be found at http://developer.berlios.de/projects/wsjt/. + + +Changes in WSJT 5.9.4 (r159): April 11, 2006 +--------------------------------------------- + +This is a maintenance release. + +1. Problems exhibited on some computers with dual or "hyperthreading" +CPUs have been fixed (or at least reduced, see below). + +2. Problems with reading previously recorded files (such as the sample +files in the WSJT tutorial) have been fixed. + +3. Bad data could cause an error message "Error in KV decoder, or no +KV decoder present" in the console window. Fixed. + +4. The delay between PTT assertion and start of Tx Audio, and the +delay between end of Tx Audio and release of PTT, have been increased +by 0.2 s. In addition, a bug in the T/R timing logic was fixed. + +5. There was a minor bug in computing the position of the moon. (The +displayed Az and El of the "home station" were correct for a time 100 +seconds earlier than the actual time.) This has been fixed. In +addition, refraction adjustments are no longer made in the Sun and +Moon elevations. + +6. A minor bug when displaying large negative Doppler shifts in the +file azel.dat has been fixed. + +7. As an aid to future development of WSJT, the program is now capable +of transmitting "test files" with arbitrary audio content. + +NOTE: If you have a computer with multiple CPUs or a CPU with +hyperthreading, and if WSJT 5.9.4 does not run properly for you, +please reboot your machine, enter the BIOS Setup screen, disable +hyperthreading, and see if WSJT then runs properly. Then let me know +the results of this test. Note: you will probably notice very little +(if any) degradation in performance by leaving hyperthreading turned +off. For now, this is the recommended procedure if you have problems +with it turned on. + + Changes in WSJT 5.9.3: January 26, 2006 --------------------------------------- This is a minor maintenance release. @@ -8,9 +146,8 @@ This is a minor maintenance release. 2.
