One additional point: Apparently there is no bi-directional IGate within 
range of a D72 at HRO.  I tried answering your CQ SKYWARN, but received 
nary a single ack.  Given that there was also no response from you 
(other than another CQ some time later), I suspect you never saw the 
messages I sent you from SeaWorld nor any of the other non-responded-to 
messages shown at http://aprs.fi/?c=message&call=WB4APR-7&limit=100

Then it is only 1 button push!  Why cannot we get all DIGI operators to add these objects???

Hence, the importance of choosing a UNIQUE object name.  There are at least a dozen of each of the above freq objects.  Easy to see.  Just http://map.findu.com/146.82* for example.

But now a day later I cannot resolve it on FINDU because there are two "meeting" objects in Canada.  Although APRS itself can resolve the differences between "Meeting", "MEETING" and "Meeting!", FINDU does not.  FINDU does not honor the case-sensitivity of Object names, and cannot distinguish punctuation marks in object names.

> 9) SORTING on the D710, D72, FTM350 (new vx8?) also makes it easy to find ECHOLINK EXXXXXX and IRLP IRLPXXXXX nodes too.  ANd with the automatic one-key TUNE/QSY functions, it is possible to bring up these VOIP nodes with one key press.

All major airport hubs should have a local WIDE1-1 digi to make sure travelrs with their APRS HT's can get info as soon as they land, or while stitting there for an hour waiting to leave.  (good luck with TSA!)
