Hi Marco The correspondent yesterday had confused MaxDrift setting (which we use on EME (mainly) for a special operating situation using a multiple decoding option of Q65) with Ftol.
Happy to hear that the proper settings work for you now. 73 Charlie DL3WDG On Sat, 21 Dec 2024 at 13:02, Marco Calistri via wsjt-devel < wsjt-devel@lists.sourceforge.net> wrote: > Hello Uwe, > > I read someone says to set F tol respecting a certain range (0-100 Hz) and > other OM telling that it must be set to 0, otherwise the number of decodes > will drop a lot. > > This is my last doubt about it! > > Yesterday I set F tol to 50 Hz and Rx frequency to 750 Hz and my WSJT-X > has not crashed ☺️ then the instructions you all have provided, have been > perfect! > > Best regards! > > PY1ZRJ > > Inviato da Outlook per Android <https://aka.ms/AAb9ysg> > ------------------------------ > *From:* Uwe, DG2YCB via wsjt-devel <wsjt-devel@lists.sourceforge.net> > *Sent:* Saturday, December 21, 2024 8:16:48 AM > *To:* wsjt-devel@lists.sourceforge.net <wsjt-devel@lists.sourceforge.net> > *Cc:* Uwe, DG2YCB <dg2...@gmx.de> > *Subject:* Re: [wsjt-devel] Repetitive program crash 2.7.0 RC7 > > Hi all, > > Allow me one question: If you have no idea what Ftol means, why are you > changing the values preset by the program?
