=== New in Version 1.8
|
||||
|
||||
For quick reference, here's a short list of features and capabilities
|
||||
added to _WSJT-X_ since Version 1.7.0:
|
||||
|
||||
- New mode *FT8* designed for fast QSOs
|
||||
|
||||
- New tool *FreqCal* for accurate frequency calibration of your radio
|
||||
|
||||
- Improved decoding performance for JT65, QRA64, and MSK144
|
||||
|
||||
- *SWL* option for third-party decoding short-format MSK144 messages
|
||||
|
||||
- Experimental amplitude and phase equalization for MSK144
|
||||
|
||||
- Options to minimize screen space used by *Main* and *Wide Graph*
|
||||
windows
|
||||
|
||||
- New set of suggested default frequencies specific to the three IARU
|
||||
regions
|
||||
|
||||
- Enhanced scheme for managing table of suggested default operating
|
||||
frequencies
|
||||
|
||||
- Improved CAT control for many radios, including those controlled
|
||||
through Commander or OmniRig
|
||||
|
||||
- Bug fixes and minor tweaks to user interface
|
||||
|
||||
