Well, here in L.A., the Southern Cal Wireless User's Group (SoCalWUG - a
wi-fi interest group) used to routinely beacon a restaurant fork/spoon
symbol at the location of their monthly meeting in the back of an
International House of Pancakes for a day before the meeting. More than
once it reminded me that this was the night for the meeting.
I beaconed objects from the Amateur Radio Expo held last October at the
L.A. County Fair. I actually had a local ham call me on 146.52 after
seeing the object on his map.
Recently, during a fire in the Riverside area about 50 miles east of
L.A. , the frequency and PL of a voice repeater in the area of the fire
was beaconed as an object. It caught my attention because they
(erroneously) used the Mic-E symbol on it, but it turned out to NOT have
any APRS capability.
About two months ago, I was at a Wal-Mart one evening when suddenly
everyone was evacuated from the store. From my laptop mobile in the
parking lot, I started transmitting an object with the bullseye symbol
and the text "WalMart Evacuated -Bomb Scare" for an hour or so.
Once when I was heading north on I-5, I came across a wild fire in the
"Grapevine" pass area about 50 miles north of L.A. From my mobile
laptop, I actually originated a fire symbol object for about an hour. I
also used my SSTV mobile LiveCAM to send some live shots of the fire on
20 meters as I drove by. I was able to then refer the stations I was
sending the pics to, in Colorado and Michigan, to findu to see the exact
location I was sending from.
Another time when I was heading east into the Sierra Nevada foothills, I
got stuck in a traffic jam on Cal Rt 88 caused by an 18-wheeler on it's
side blocking all lanes. Again, I originated an object from the mobile
laptop while waiting.
In all of these incidents, the ability to click an object down on top of
my current location on the map in UIview or APRSpoint, automatically
picking up the coordinates from the map, was very useful.
Anyone have any thoughts about what symbols would be appropriate for
these incidents? (The fire was obvious, the others are ambiguous. I
usually use the circled-zero to create a target-like effect for traffic
accidents.) Do we need a new smashed-car symbol, similar to the
crashed plane, for road accidents?
