Subject: APRS bulletins

One more thing about Bulletins. They are NOT implemented correctly in
MOST APRS clients... Here is what is wrong with most implementations:
1) They are not placed on the one SINGLE VIRTUAL Bulletin display
2) Users are not forced to read them, or notified when they are updated
3) The originator cannot update them line by line
4) The originator cannot erase them from the display
The result is again, they dont work as originally designed except in
APRSdos and a few others... Here is how BULLETINS in an APRS event are
supposed to work:
APRS bulletins were designed to represent a ONE PAGE VIRTUAL display of
the most important information relative to what was immediately happeing
at an ARPS event. This display was called the BULLETIN SCREEN and it was
supposed to look THE SAME AT EVERY STATION.
It was supposed to look like a virtual BULLETIN BOARD like in the EOC that
everyone could look at to see what was immediately pertinent to what was
going on. It was limited in size (one screen) to force brevity,
conciseness and filtering of only the most important information of
immediate use. Further, each line of the BULLETIN display page could be
individually edited, replaced, changed or deleted without having to send
the whole bulletin again. There was no such thing as an OLD bulletin.
When replaced, edited or updated, the old one didnt exist anymore...
AND EVERYONE IN THE EVENT SAW THE SAME BULLETIN SCREEN!!!!! With all the
SAME ACTIVE lines. Its like everyone could see EXACTLY the same
virtual presentation that everyone else was seeing.... And it was called
the BULLETIN screen so there was no confusion between operators as to
where to find the latest info.
For example APRS is supposed to replace an OLD BLN3 with a new line BLN3
if received from the same user. Further, the lines are alwasys supposed
to be sorted so that they always dispaly in sequence no matter when
received. By overwriting his BULLETIN lines on the single
virtual BULLETIN board, people could ERASE or update old info. Plus
every operator is alerted with the morse letter B to alert him to glance
at the BULLETIN screen to see new or updated data. He doesnt have to dig
through hundreds of old bulletins to see what is the latest. He sees
whate everyone else is supposed to see. A single virtual SCREEN of the
"currently active bulletins".
What we have today by some authors is an infinitely long list of every
message, bulletin and announcment ever sent. There is no way of knowing
if you got everything, nor what is current, nor wnat is the latest, nor
what was supposed to replace or overwrite what, nor how far back in the
tons of messages you have to look. Nor what bulletins apply to your
event... This lack of a one page limitation of BULLETINS by these new
authors was considered PROGRESS.
The result is we are awash in an almost infinite list of onging bulletins
that just go on and on and so no one ever reads them. The functinonality
of the VIRTUAL BULLETIN SCREEN containing the most significant information
needed at an event was lost...
Now you post a bulleitn and half the people never see it. Nor do they know
what is pertinent NOW. Nor do they all see the SAME INFO...

Anyone know WB4LDS (-4) or K5IJX? These stations are showing up in Tokyo
but I'm pretty sure they aren't on that side of the pond. If anyone can
contact them and let them know that their stations aren't showing correctly,
that would probably be helpful. I would really like to know more about
WB4LDS's backpack tracker, too!

Speaking of SPAM on my kenwood d700... I commonly get messages from NWS
offices in distant places... how can I filter so that I only get the ones
from, say two NWS offices nearest to me?

WB4LDS-14 is showing up 26 miles from me in downtown Tucson. Right where he
should be. At least he was 25 minutes ago per my RF station. Don't know
what got onto the internet.

You guys are talking about two different SSID's!
http://www.findu.com/cgi-bin/find.cgi?WB4LDS*
-4 is in Japan and -14 is in AZ.
Both made it to the internet from the same I-Gate.

The Radio Shack Digitravelers default to a location near Tokyo - perhaps
he's using one of those and hadn't yet achieved lock when you saw him on
Findu.

Ok, the problem is NOT with his station!
It is with the I-gate operated by KV4OA that is running APRSD version
2.1.4vksb.2
He needs to QUIT converting packets before putting them to the Internet
stream! There is a bug (I don't know the APSD history for bugs) but it does
not decode packets correctly.
I am having the SAME problem with KB5LS in Lufkin Texas. He is causing BIG
problem in our area since he is also reverse gating packets and decoding
them. This is our single largest packet duplication error problem here.
(and the bug make stations appear in the middle of the Atlantic when they
drive along I-10).

I see those sometimes too. I thought that NWS messages were supposed to
go to a message address so that people would not get them uniless they
added the special address to their message groups. Maybe Dale can remind
us all of how it is supposed to work...

Per the spec, NWS messages go to NWS-XXXXX where XXXXX is the type of
message. Kenwood has programmed the D7 and D700 to always store those
messages. There is no way to filter them out. Dale, however, has
reduced the number of those messages by only sending warnings, alerts,
etc. to those addresses and sending the text to SKYXXX where XXX is the
weather office identifier. The Kenwoods will only pick up on those if
you have SKY* or SKYXXX programmed in as one of your groups.

Also remember, the default for aprsD is to set FILTER ON with Kantronics
TNC's. This will mangle Mic-E packets causing the packets to show
improperly, even if packet conversion is turned off.

You know Bob, I hever thought I would find myself on a soap box lecturing
you about the proper use of aprs but I find myself in that precarious
predicament.
Here's the deal. Bulletins and messages are not the same thing. If the
Kenwoods are using up a 'message' slot to store a 'bulletin' then they are
poorly engineered and have a problem that seriously needs to be looked at
and then corrected.
For that matter, if I owned a Kenwood and put it in my car and then drove
the car to work, well, most people get out of their car and go inside
their place of employment. They stay for several hours. Usually around
eight or so. You can't convince me that the message it received five
minutes after I got out is still gonna carry much relevance. Now, if the
Kenwood will in fact only store ten messages and then stops receiving
further messages then it's poorly engineered and I'm not gonna try and
drive around it. What it should do is store then ten most recent
messages. That way perhaps the stuff that is stored would still be
relevant.
My digipeater will continue to beacon it's "PATH=RELAY,WIDE2-2 for
mobiles. Tnx." (A message specifically worded to accomodate the Kenwoods
BTW) beacon every thirty minutes to advise the mobile user community about
proper paths in my area. This is a relevant piece of information,
particularly for itenerant users. If it's clogging up your defective
Kenwood tough. Go buy something that works.
