0224e76c44 Change the definition of "d" so that width of generated tones is equal 
to the requested Doppler spread.  Previously they were wider by the 
factor 2*sqrt(log(2)).

4de778c4e7 Reverting r6531 and replacing with correct fix 
The WSPR  message is unpacked  into a symbol  per byte array  which is
processed  by  encoding a  whole  number  of  bytes of  message,  this
requires the output  array to be bigger than the  number of symbols to
accommodate  extra values  that are  not part  of the  message due  to
rounding up to whole bytes. I.e.  176 (11*8*2) elements to contain the
162 symbols.

020803e901 Fix an array size parameter error in gen9.f90 
Also use assumed shaped for dummy argument arrays where possible.

If a  Fortran procedure has  an interface declaration,  which includes
all procedures exported  from modules, then dummy  arguments should be
declared as assumed shape if possible.  This allows compiler generated
array bounds checking and compile time array shape checking.
