Disponibile la RC7 di WSJT-X v. 2.7.0
Release: WSJT-X 2.7.0-rc7
September 30, 2024
-------------------------
WSJT-X 2.7.0 Release Candidate 7 brings significant improvements for the new SuperFox mode. It introduces a new verification system which replaces the previous one, and works for both the SuperFox mode and for old-style Fox and Hound operation. All code for SuperFox operation is now open source.
IMPORTANT: OpenSSL v1.1.1 or higher is required for the real-time verification of Fox and SuperFox messages.
Enhancements to the SuperFox decoder:
- Performance of the SuperFox decoder has been further improved.
- You can now set individual FTol values and tune the decoder to the exact sync frequency of the SuperFox signal if it is not exactly 750 Hz. Both result in a better decodability in certain situations.
- Important: The Rx frequency must be set close to the sync frequency +/- FTol, for example 750 +/- 50 Hz.
Introduction of a new Fox verification system:
- The new Fox verification system uses one time passwords (OTPs), and works for the SuperFox mode as well as for old-style Fox and Hound operation. It can be enabled by the new OTP checkbox on the Advanced tab of the Settings dialog.
- Fox or SuperFox stations send individual OTPs via radio. Hounds automatically check the validity of the received OTPs in real time from a server when there is an internet connection. Otherwise, the validity can also be queried manually later. OTP verifications can only be retrieved once the transmission has already taken place.
- You may optionally display the received OTP values by checking the box "Show OTP messages".
- If the Fox or SuperFox callsign is verified by receipt of the correct OTP, the background color of the Hound or Super Hound label switches to green.
- Theoretically, DXpeditions can set up their own OTP server, however, we recommend using the server at https://www.9dx.cc.
- Use of the new Fox verification system requires an OTP key. The system uses open source code and standard encryption technology. For testing purposes, non-verified SuperFox transmissions are now possible without a key.
Improvements to SuperFox/Hound operation:
- SuperHounds must now first decode the SuperFox before they can call, and a QSO must be started by double-clicking on a SuperFox decode. (Note that calling the Fox blindly not only leads to unnecessary band utilization, but can also significantly reduce the QSO rate due to unanswered (Super)Fox replies.)
- Switching to SuperHound mode automatically sets the Rx frequency to 750 Hz. The previously selected frequency is saved and restored afterwards.
- Right-clicking on the H button now activates/deactivates SuperFox mode.
- A flaw resulting in sub-optimal SuperFox QSO rates has been corrected.
- SuperFox decoder now does a more thorough job of rejecting QRM from non-SuperFox signals.
- Fields in the SuperFox payload not otherwise used in a particular transmission are now set to known nonzero values. Do NOT use RC6 or earlier versions to decode SuperFox transmissions from RC7 or later.
- Old-style Fox stations can now transmit free text messages (up to 13 characters) by using an available stream.
- Some enhancements useful for Fox operators: Active Station Window now shows band activity. Hound callsigns can be highlighted via UDP API, and assigned a score for sorting via UDP API. Fox Tx frequency is preserved when switching in/out of Fox mode.
- UDP Status Update messages now include information on how many callsigns have highlighting applied, and how many callsigns have a score assigned.
Other enhancements and fixes:
- In FT8 mode, the Settings dialog no longer resets the VFO frequency to band/mode default unless really needed.
- Several code improvements specifically for macOS.
- Updated CTY.DAT and Hamlib.
