Yes.

No.  Ignore the HITS.  That was for a DF kit at the time that output that data direct to APRS.  It is no longer availble.

The way to display the QUALITY is by the WIDTH of a wedge.  The better the quality the narrower the wedge.

SInce APRSdos could not plot wedges, I plotted the bearing line in "dottedness".  A high quality report was a solid line.  A low quality line is a very sparsely dotted line.  But today, better programmers should simply make wedges.
