Hi. Does anyone know of an inexpensive utility that can perform the said conversion? I've spent several hours googling this matter, but haven't found a good solution. Thanks.

 

Hi,

I've looked for years, too. At one time, I looked up the spec's for 247X and thought it would be possible to write a routine to interpolate the extra stuff into a 247D file, but have never tried. Let us know if you find something. You'll have the gratitude of the last dozen or so Tango users left.
