Unfortunately, the AndFlmsg app has no message history.

I have been a FLDIGI user for at least a decade. I love the ease of upgrading. In short, the FLDIGI suite just works.

Windows has flagged the most recent version of FLGRIG as containing a virus. Please advise.

I have Windows 11 and for the past several days I have downloaded the Fldigi program for my Yaesu FTdx-10. When I click the desktop icon it takes between 2-4 minutes for the program to start. When I try to access any of the settings the program seizes up and states that the "program is not working." It takes another 2-4 minutes for it to start working only to repeat the process again. I have uninstalled the program several times and reinstalled it only to have it do the same thing each time. I presently have wsjt-x installed and it works flawlessly with my radio. Any help would be appreciated. PS. Fldigi work fine on my Mac.

Hi, I am using a Mac Mini with Apple M2 chip running MacOs 15.0.1. Fldigi still does not open on this platform; It opens and immediately closes. I hope you can fix this; I really miss this app.
