Joe Taylor 6e308f0018 More attempts to diagnose or fix the FT8 "hung decoder" issue. 
On the Fortran side:
 - For the nzhsym=41 activation, bail out if m_ihsym reaches 45
 - For the nzhsym=47 activation, bail out if m_ihsym reaches 48
 - Change the format and content of what's written to fort.71
 - Change msdelay from 10 to 1

In mainwindow.cpp:
 - change format and content of what's written to qDebug
 - always start FT8 decoder at m_ihsym = 41, 47, and 50
 2020-03-12 12:33:34 -04:00
Joe Taylor 199ff3dd3d Experimental work-around for FT8 decoding on slow computers. Important changes: 
- don't start function decode() is decoder is already busy
  - send updated m_ihsym to jt9[.exe] via ss(1,1).  Bill won't like this!
  - jt9 bails out of the 41-buffer pass at m_ihsym=45.
