: 1 FSK441 įSK441, introduced in 2001 as the first communications mode included with WSJT, is designed to support communication using streaks of radio-reflecting ions created in the ionosphere by the trails of meteors entering the Earth's atmosphere. : 17 Two other modes, WSPR and Echo are included for measuring propagation and testing moon bounce echo. Some modes have derived submodes with larger tone spacing. : 6 WSJT-X 1.8 additionally implements the "slow" JT9, FT8, and QRA64. As of WSJT10, supported fast modes are JTMS, FSK441, ISCAT, and JT6M, and the slow modes are JT65 and JT4. While fast modes send character-by-character without error correction, the slow modes aim to optimize for minimal QRO (high-power) use. WSJT's communication modes can be divided into fast and slow modes.
JT65 HF MANUAL SOFTWARE
The software carries a general emphasis on weak-signal operation and advanced DSP techniques however, the communication modes rely upon different ionospheric propagation modes and may be used on many different bands. As of May 2018, the latest WSJT version is WSJT10. This backwards-incompatibility includes JT64A, such that the preview release of JT64A in WSJT7 cannot communicate with the stable release of JT64A in WSJT8. As of version 8.0 (referred to as colloquially as WSJT8) the available modes changed completely such that WSJT8 now offers 5 different modes (JTMS, ISCAT, JT64A, JT8, and Echo) - none of which are back-compatible with WSJT7 or earlier releases. WSJT versions up through 7.06 r1933 (referred to as colloquially as WSJT7) and earlier were aggregations of previous versions, and as such WSJT7 contained 16 different modes (FSK441, JT6M, JT65 variants A - C, JT2, JT4 variants A - G, WSPR, and a preview of JT64A). Currently, the program is written in Python and C, with several utilities written in Fortran. Although Joe Taylor was the original developer (and still acts as maintainer), several programmers are currently involved in writing the software. This licensing change required substantial rewrites and took several months to complete. Since 2005, the software has been released as open source software under the GNU General Public License. Communication modes have been both added and removed from the software over the course of its development. If you want to try JT65 or already tried it but not completly happy with it, I suggest you to give a try to WSJT-65 and/or JTAlert.WSJT was originally released in 2001 and has undergone several major revisions. I use Ham Radio Deluxe for that and it seamlessly connect to it reading all the logs (and calls) I already made and writing for me new ones made in JT65 when the “73s” message is sent. It is very configurable and the most intesting thing is that it can be configured to work with some of the most popular “logbook” software. It is made to alert you about CQs, new Calls, new DXCC etc. This really changes the JT65 experience and helps a lot people that like to use this mode. I still don’t know why this happens but I hope to find out soon as JT9 is interesting even if now so “popular” as JT65.īut the real GEM is another piece of software that is made to work with both JT65-HF and WSJT-X: JTAlert. I’m still not been able to do a QSO with it as every time I try, the power of the communication is very “random” or zero and so I’m not able to do any stable communication. It happened to me a few times now and it’s very annoying.Īlso… WSJT-X supports JT9 a sort of “streamlined” (smaller bandwidth) version of JT65. The only drawback is that the beta version I’m using (1.2 r3563) is sometimes a little unstable and crashes. Here’s what my screen looks like with WSJT-X (and JTAlert, more about it below):
JT65 HF MANUAL MANUAL
Too long to list them here but they are easy to understand… even without reading the manual □ There are also a lot of options for the waterfall and for the communication. They both can be resized and you can “adjust” them almost how you want. It has two windows: one with the activity and control panel and the other (optional) with the waterfall. I know, I should always read the manual but I do simply because I want to go more in depth about what I’m doing not because I can’t understand where to even start □Īnyway… WSJT-X is far from perfect but much much better than JT65-HF. The only way to understand what to do is read the manual. It is totally counterintuitive and make a simple mode like JT65 quite difficult to understand.
JT65 HF MANUAL WINDOWS
I didn’t like the graphic interface of JT65-HF… very OLD style and also I don’t like things that windows that don’t resize. On the encode/decode side I switched from JT65-HF to WSJT-X. In the last couple of days I discovered a couple of piece of sofware that made me come back to try JT65 and appreciate it even more that I supposed it could happen □ I already wrote a post about JT65 mode but I didn’t use much after that period and almost did all my QSOs with PSK31.
