1. Fix the nfqso < nf1 but in qra64.f90.
2. Delay splash screen until after main window starts. 3. Keep cbTxLock enabled in QRA64 mode. 4. Update v1.7_Features.txt. git-svn-id: svn+ssh://svn.code.sf.net/p/wsjt/wsjt/branches/wsjtx@7005 ab8295b8-cf94-4d9e-aec4-7959e3be5d79

nothing". You will see little or no "garbage" on your screen.

Standard MSK144 message frames are 72 ms long, compared to 117 ms for

purposes we recommend a T/R cycle duration of 15 s, but 5 s and 10 s
