[aprssig] D700 dP bug ? Redux "dT"

{ know this isn't a D700 forum, but post anyway}

Changing ONLY the D7 "STATUS TEXT" (Menu 2-9}  (and NOT the POSITION
coords)  then manually  re-beaconing direct to the D700 -   it indeed does
NOT show dP on the D700, but interrupts the display with the call-SSID
and the STATUS TEXT !

OK "Logable" ... got it!

.........  SO ........

/ frustration-rant interrupt triggered/

(And here's the sorta' Ah-ha}  The D700 Spec-Comm manual (p14)
says the meaning of the dP flag is "Duplicate position comment" 
...  and  ...   includes "Same comment as the
previous...".    Sure! Now that I KNOW how it works, the
manual makes almost 100% sense. 

  Here's the two new Magic decoder ring entries: 

   Position comment =  STATUS TEXT

  dP = Duplicate STATUS TEXT from already listed station - NOT Position.

More fodder for the "How-it-works and How-To" document.

I say "sotra Ah-ha" because of the mixed terminology to common in
explaining APRS which makes this stuff hard to learn.-- when it
shouldn't be.   (like UI /  UNPROTO / Unnumbered)

Like I tell my students about electronics terminology:

  Learn the terminology correctly.  If your head hurts, it makes a Really Big difference whether you
have a head-ache or a sub-dural hematoma ---  Learn and use the
correct terminology!

  In this case Pick one and stick with it.

/Clear rant-interrupt  flags/  I'll go lie down and take an aspirin.

And, uh... Thanks to all for explaining many things here.

Could you test that?  What if you changed the status text?
I'd be curious.  In APRS, that is considered a loggable change.

Yes, it is way up there on my
 list too...
