A user-defined VOR waypoint must contain an identifier, magnetic    variation,    latitude,    and    longitude.        The magnetic variation may be manually entered or, if one is not entered, one will automatically be calculated and stored.      A   VOR   frequency   may   be   stored.      The procedure for creating a user-defined VOR waypoint is similar   to   that   just   described   for   creating   a   user- defined airport waypoint.  Begin by selecting the VOR waypoint  pages.    The  VOR  identifier  can  be  one  to three   characters   in   length.      A   user-defined   VOR waypoint page contains the user identifier at the top of the  page  and  three  lines  of  dashes.    The  top  line  of dashes  may  be  filled  in  with  frequency  and  magnetic variation.  The second line is for latitude and the third line is for longitude.  A user-defined VOR is stored as an Undefined (U) class.  Refer to Figure 3D-32.
