WinWarbler is the digital mode component of the freeware DXLab Suite. Version 7.5.9, released earlier today, includes G3YYD's 2Tone RTTY demodulator, which provides excellent weak signal decoding and handles selective fading that suppresses a signal's mark or space tone. A screenshot showing simultaneous decoding of Mory JG0TCL's signal by both the MMTTY and 2Tone demodulators can be seen here
If an external HF modem is available (KAM, PK232, MFJ, SCS PTC), WinWarbler can display a third receive pane showing the characters it decodes.
DXLab users can obtain this update by clicking the WinWarbler Update
button on the DXLab Launcher's Configuration window. Ops interested in learning more about DXLab should visit www.dxlabsuite.com
