That's better, but roger beep?...really, now!  You're
staying too close to the box.  Step out more.
You have the speech synth, use it ! !

This is good:
> it would SPEAK  ...  Just phase delay any audio by
the amount needed for the virtual position.

   I was thinking more like:
 "WB4APR-VAN-two o'clock, three miles,  closing as 45
m p h relative."

 "W3XYZ, TRUCK, eleven o'clock, 1-2 miles headed 9-0
degrees at 4-5 m-p-h"


 "W2GPS-JEEP-dead ahead, inbound course, 1 mile, 2-5
m-p-h,  collison course in 1 point 2 minutes"

OR maybe

"W1ABC car, ten o'clock, three mile, east bound at 4-5
m-p-h.  Course intersect 1 point 4 minutes with
3-0-0-feet separation"

[ you'll be 300 feet apart when the first one crosses
the path of the other (at current speeds / directions 
a.k.a. dead reconing)]

  Just speaking, with clarity, the bearing, speed,
direction info on the D700 display would be better
than a bleepin'  beep.

But then again... in an APRS-busy area...

That being said, there is something to be said about
information overload.  On fighters with voice
wqrnings, there are times when that stupid voice,
constantly announcing that your tail is on fire, is a
nusance and detracts from what's top on you mind --
which is saving your Kiester.  Lesson learned from
that infamous Florida "light bulb" crash...Fly the

The filtering would, indeed, be critical.
