Hello Scott,

Even "?help" is not standardized, it is yet another message (even ? is
optional in case of DIGI_NED). In the default digi_ned.mes I used for food
and restaurants:
| ?F|Food
| what: FAst Med QUality
If you send "?f" or "?food" then it will respond with "what: FAst Med
QUality" so the user can choose fast-food, medium qualtity food
(tourist-grade) or best quality (top restaurants).
| ?FA|FAst|MC
| ;MCDON-CEN*010000z5212.75N\00557.82ERMC Donald Center
| ;MCDONA-A1*010000z5210.77N\00559.13ERMC Donald South
| Fast food objects sent
When the user sends "?fa" or "?fast" the response is "Fast food objects
sent", two objects for both Mc Donanld's in Apeldoorn (tbe town where I
live) will be send. I used symbol "\R", which is the icon for a Restaurant.
Alternatively the user can use "?mc" when looking directly for a Mc Donalds.
| ?M|Med|Medium|Valk|Mo|Motel|RES|RESt|REStaurant
| ;CANTHAREL*010000z5210.36N\00554.43ERMotel de Cantharel
| Restaurant object sent
When the user sends "?m", "?med" or "?medium" it will send the reply
"Restaurant object sent" plots Motel "de Cantharel" on the map.
Alternetively the used can use "?valk" when looking for one of the many
"Van der Valk" places, "?mo" or "?motel" when looking for a motel or
"?res", "?rest" or "?restaurant" when looking for a restaurant. This is
only an example, I could have put in a lot more restaurants in our area.
| ?QU|QUality|K|Keizer|HOT|HOTel
| ;KEIZERSKR*010000z5213.80N/00556.66EHHotel de Keizerskr
| Qual. Hotel object sent
Okay, you get it, this one plots one most expensive hotel in the area where
you can also order quality (and expensive) food. Also here I could have put
in more. Note the icon here is a hotel, because that is what it is,
eventhough it has an excellent restaurant.

Yes, that would be good. In my setup you have to use "?restaurant" to get
restaurants, using an Icon would make it language independent and more
intuitive.
APRS clients could implement this too, they could stick to translate an
request with symbol type to send it as a query. For example clicking the
restaurant icon could send query "?\R". Alternatively the name mentioned in
the spec could be used. In the example the query should be "?Restaurant".
We need a standard if we want to use this using traditional APRS
(ClosedTRAC...).
Note that in case of queries to the DIGI_NED digipeater case is not
considered. This makes typing queries on a TH-D7 easy (in my case it is
faster to type uppercase). I use the case in the help response to show
shortcuts; for example "REStaurant" means that "?restaurant" works but also
"?res".

Reason for me to put it in the digi is because this is a high-profile site
with excellent accessibility. It will be noticed by the visitor. Since this
could be a mountain top digi there is no internet connection... Each digi
just serves its own local area. No huge database to maintain, just the
local operatior who knows the local situation the best. I think it will be
hard to maintain an internet "have it all" database; who is going to update
it when the situation changes and how to avoid obsolete bogus entries - who
is reponsible for the correctness of the information.
You can leave it to home-stations to provide this service, but I don't
think it is so clear who offers the service, you have to find out in each
area what way the service is announced and where to send your messages too.
A broadcast-service like QDOS also works, but then you have to make sure
there not multipe stations who answer that.
Kind regards,
Henk.

FWIW, that only works on a KPC 3+ or a 3 with later than 6.0 rom.
I'm uplinking the muncie area repeaters similarly now, with all three
filled. LT1 is 2M 2 is 220, and 3 is 440.

Yes, that was the KPC-3 example. Any BEACON from any TNC will work.

Great! One idea in this case to lower QRM. If they are co-located put
them all in one packet to show up like this:
OBJ Name: VOX-RPTRS
LINE 1: 146805+107
LINE 2: 448335-156
D700 3: 220525+
or something like that. This way the VOX RPTRS will catch their EYE in the
list, but the freqs will be on the station display. Only the thrid one
will show on the D700 and the PL wont fit because it can only take 8
characters.
Just some ideas...
THough I would like to have some standardization so that someone can build
a PIC processor to parse these and QSY the radio automatically...

This sounds strangely like my idea for local 9600 baud nets, where the
local net freq would be put out on the 2m net, along with location, and let
the client sw select the best signal or closest system from the available
choices..

Hmm. I think I've got an old cell phone around somewhere. And I'm sure
I've got a lot of gasoline. Sounds like it's time for some real-world
experiments. =] Even trying deliberately to get a spark out of a cell
phone battery sounds like it might be difficult, though. Maybe if you
dropped it on a pile of steel wool...
I wonder if there are any rules against using a vacuum cleaner at the gas
station...

What is the difference between a normal APRS position, an item and an
object?
