2. Remove (or comment out) most qDebug() statements. 3. Swap positions of labels 2 and 3 on status bar. 4. In "Split Tx" mode, transmit audio always between 1500 and 2000 Hz. 5. Rearrange positions of WideGraph controls. git-svn-id: svn+ssh://svn.code.sf.net/p/wsjt/wsjt/branches/wsjtx@3535 ab8295b8-cf94-4d9e-aec4-7959e3be5d79
