SpecJT and frequency labels on lines of decoded text. (Needs checking!) 2. Corrected logic for Rx buffer assignment on program startup, and for when a transmission is started late. (Needs checking!) 3. Diagnostic display of kbuf, kk, and kxp/96000 in status-bar msg7. git-svn-id: svn+ssh://svn.code.sf.net/p/wsjt/wsjt/branches/map65@943 ab8295b8-cf94-4d9e-aec4-7959e3be5d79
