Using IC-7300, Windows 10.
I have lost the Diddle when using FSK RTTY. Use to work perfectly.
In the MTTY setup under the TX tab diddle LTR is checked.
What else can I check on that might fix the problem?
+ As a first step, I suggest that you direct the Launcher to restore WinWarbler's settings from the Workspace that you directed the Launcher to create when everything was working correctly.
