[aprssig] UI-DIGI dupe

Not positive that this thread is about the UIDIGI firmware (which I call 
UIDIGI-ROM to avoid confusion with the term UIDIGI which is used in such 
devices as the KPC3+ etc), but if it is, then I have just verified that 
a UIDIGI-ROM firmware equiped TNC2 (for example MFJ1270B/C) configured 
per http://dxspots.com/FIX14439_UIDIGI-ROM.zip properly does duplicate 
suppression based upon the setting "DuplicateSuppression = 30", which is 
the value stated in my example configurations.  My testing was done with 
paths of WIDE1-1,WIDE2-1; WIDE1-1,WIDE2-2; and WIDE1-1,WIDE3-3.  The 
path actually has nothing to do with the DuplicateSuppression of 
course.  Identical packets sent within a 30 second period were ignored.
