Bill Somerville 488c2e8066
Cleanup and refactor Fortran shared memory usage 
also added some missing locking for the ipc(1) value in ft8_decode().

Joe Taylor 649a79dfc1 New IPC trial: use shmem instead of .start .stop .quit files. 2020-03-14 17:06:54 -04:00
Bill Somerville 523e9a1a07
Enhanced process control for jt9 executable 
The wsjtx  process creates control  files .start, .stop, or  .quit and
the jt9  process deletes  them.  This  is intended  to avoid  any race
conditions that get the processes out of sync.

Joe Taylor 68c942a70e Correct the 47-buffer bailout place. Change bailout times 45->46 and 48->49. 2020-03-12 13:00:42 -04:00
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 d69cb49e9a Diagnostic writes to fort.71 in jt9a.f90. 2020-03-11 14:02:19 -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.

2. mainwindow.cpp: based on the time when <DecodeFinished> is received, calculate
mswait to try to place the killFile time at 0.75*m_TRperiod.

Steven Franke 0ca6cbb575 wsprd: improve decoding and reduce the number of false decodes 
Hashtable entries now include the 4-digit grid obtained from the most
recent Fano decode of the callsign. The stored grid is used to validate
OSD decodes. OSD decodes of type 1 messages are accepted only if the
callsign is present in the hashtable and if the grid matches the grid
stored in the hashtable.
