The program is expecting decimal entries.  After looking over the 
grid conversion routine (which was from another program) I finally
rewrote it with my understanding of the grid system and now the 
program gives the same result as your other ones.  

So, everyone be aware that the 5th and 6th digits might be off.  
This isn't a problem for the beam heading process - but don't 
get on in a UHF contest with those grids!

This will be fixed in 5.83 - whenever that becomes necessary.

Thanks for finding that one Tony!  You guys are great.
