That is if you have to resort to tracking it down. If it's like most APRS
stations, it will actually be transmitting a callsign, latitude and
longitude. Just need to get someone to copy it. Of course, the operator
could enter a bogus callsign and or lat/long. Then it gets a bit more
interesting. However, it is probably like the original poster suggested and
someone inadvertently QSYd to the repeater frequency. Should be pretty easy
to track down, but there's nothing to stop people from trying to track it
down with omni DFing as well.

I didnt exlain that very well. Let me try this way. Our local radio club
has a Kids club to get kids licensed. And I have years of experience with
scouts and getting kids interested. But even when kids do get their
licenses, we rarely hear them on the voice repeater. And it is very
simple. They are intimidated by joining in on a very adult kind of medium.
And when they do, sooner or later some old fud jumps in and scolds or
fussses at them for some minor infraction or whatever...
But when that first radio contact is on CW at 5WPM or slower in the novice
band, then I dont think one ever hears a bad attitude, and even if there
was one, it is very hard to get it across in CW at 5 WPM.... In fact, I
would say the actual intelligibiity of my novice CW contacts were in the
20% range, but it didnt matter, the medium was the message. Get a call,
RST and location and move on...
Again, I am not pushing CW because it is CW or because that is the way "we
did it", but simply because it seems to have a real keen wow factor as some
kind of secret code that matches the imaginary world of dungeouns and
dragons and sorcerers for kids in the 8 to 12 year old group (for those
that have read the Harry Potter books)... etc...

Good point. Its alomst like operating HF, but wihtout antenna restrictions
and RFI, hi hi...
Thanks

Bob. Take a look at....
Sort of surprised you hadn't found that, it was at the top the search list
as a result of Googling for "CW internet".

I've heard that too. When I hear someone making a call and it really sounds
like their first time on the air, I try to go out of my way to welcome
them... or if I have heard someone else jump on them for something, I try
to call them afterwards so their first time on the air isn't a completely
negative experience.

I'll go along with that! Yeah, whether it is to foster the use of CW or to
encourage kids to learn to use a "secret" code and get them exposed to
amateur radio, it's all good. I've got a shiny new iambic key that hardly
ever gets used, and a rig with a keyer built in, so it sends perfect code
unless I really flub it. I seldom use CW these days, but it's what I grew
up with. I still find myself practising it in my head when I should be
doing something else.
Anyway, enough of the nostalgia! I think that anything that exposes new
people to the hobby, especially kids, is a good thing. Radio may not quite
have the magic that it did 40 years ago when kids are instantly exposed to
broadcast radio, TV, phones, cell phones, MP3 or MPG4 players, satellite
radios, computers... even cars with GPS navigation systems built into them!
In spite of that, if you are off on a ski trip in the middle of no-where
and someone fishes an 817 out of the pack and sets it up with a 2 AH gel
cell and strings some wire out into the trees and they call home or check
into a net, others on the trip are pretty amazed at that small package can
do. They are almost as amazed when you ski up onto the ridge and whip out
your HT up on the peak and reach out to some repeater a good days drive
away... far outside the range of cell coverage.
I think others on the list have suggested some existing programs. I haven't
looked at them, but I hope they work out for what you have in mind. My only
experience with cubs was when a "friend" took me to join up and he punched
me in the stomach on the way home. If it happened today, I would have
pulverized him, but first impressions count and that was my last visit to
cubs! If you can get more young people involved, that's great! Don't forget
to expose them to APRS at some point as well! If you can't get them
interested with fancy software, try an old time ham shack with a whole rack
full off glowing tube equipment, voltage regulators that light the room up
with a eerie blue glow and flicker in time with the CW being sent. Of
course, it helps if the person demonstrating carries on a conversation with
someone else in the room the same time they are having the QSO. That I
could never do! (Oops... that was more nostalgia. Just thinking of the
"elmer" that started up the club that I joined back in those days.)
PS - to anyone on the list. If you are responding to a comment I made,
don't bother CCing it to me. I just end up getting two copies of the
message, or replying to the wrong address.

Subject: [aprssig] APRS and Scouting National exposure
APRS at Scout Camp (global contacts)...
Ham Radio news sources are all carrying the news story about "SCCP" which
is a protocol to allow scouts at scout camps to easlily contact each other
at known times so that there will be easy contacts for working on the Radio
Merit badge.
http://www.arrl.org/news/stories/2006/07/06/102/
THis procedure also includes a recommendation that they use APRS. There
are 3 important points about using APRS to facilitate SCOUT contacts
anywhere on the planet in real time:
1) Use the SCOUTING symbol for your station. Then all other scouts can
instantly locate you on FINDU using the search by symbol URL:
http://www.findu.com/cgi-bin/symbol.cgi?icon=/,&limit 0
2) Encourage any local IGate that is in the vicinity of any scout camps to
be sure to include the callsign "SCOUTS" in their pass-to-RF list. (and
set the shortest path to get there).
3) Have every SCOUT camp add "SCOUTS" to their MESSAGE list.
4) Each time a scout camp gets on the air, have them send a message to
SCOUTS. Then via steps #2 and #3 above and the global APRS internet
system, it will go to every scout camp on the planet. Once anyone sees a
message to SCOUTS, then they can reply with a direct message to the camp
callsign and communications is thus established.
Here is my web page about APRS at Scout Camps... and other scouting ham
radio ideas.

I wouldn't hold PHG as a high standard of evidence. It can be easily
manipulated, has a really high granularity, and on my TH-D7, I can't
modify it to reflect what power level, height, etc.
The problem remains. The packet needs to be decoded to glean anything
useful.
