Your right, it has been a long time since those articles. Now open squelch
is standard in most TNC's, and if not, the equipment to do it is off the
shelf COTS. See:
http://www.paccomm.com/dcd.html
http://www.tapr.org/tapr/html/Fdcd.html
Since APRS is 1200 baud, that is what was being discussed, I can't disagree
with you on the 9600bps comment (but see more on that later).
As to present day expensive radios/tnc combo's that demand closed
squelch.... well, honestly, why is ham radio different then the rest of
society? Haven't you ever bought a lemon of a car, refrigerator or computer
even though they have been making those things for much longer then TNC's?
Ham radio is no different, there are major vendor's that continue to sell
junk to hams.
We need to communicate amongst ourselves and demand our publications don't
give these vendors a "pass" just because they buy ad space. I've complained
to reviewers on QST on at least one occasion for the lack of testing done
on some so called "9600 baud ready radio's". We all have to do this. None
of these vendors are doing ham radio any favors, as soon as they stop
making money they will pull out of the market. For ham's to demand good
products and accurate advertising helps everyone.
But that gets back to my earlier point about not all radios are suited for
packet, and apparently from what you are saying, folks are selling radios
in the present day that are not suited for packet. My only suggestion to
you is to sell it and/or use it in a different service.
Sorry....

Just to state my position...
I have not, and will not go begging to Microsoft for support of findU.
The dollar value of megamaps/month service is quite high (six figures), a
corporation is not likely to give it to anyone that is not a non-profit
corporation so the value could be deducted on its taxes. I have no
intention of dealing with the hassle that goes along with being a legal
non-profit.
I know this will anger some people, but findU, APRS, and amateur radio are
hobbies in my view, not public services. True enough, they can be used for
public service, but 99% of the time, they are used as a hobby.
To me this would be like a marina owner going to Exxon asking for free gas
to give away to all boaters, because sometimes boats from the Coast Guard
Auxillary gas up there. I could not do it with a straight face.
Pursuit of such an expensive grant is a time-consuming, frustrating process
involving schmoozing, not one of my talents, and not something I would
enjoy in the least.
The tech guys at mapblast were undoubtably aware of findU, and perhaps did
not kick the knowledge upstairs because they thought it was a cool use.
Once a bean-counter in Microsoft figures out findU users got hundreds of
millions of free maps, they may send the matter over to their lawyers,
Microsoft can afford much better lawyers than I can, and whoever has the
best lawyers wins in America.
Finally, support leads to obligation, and I do my best to be beholden to no
one.
So long as a company had a free service on the web, and did not have terms
of service which precluded findU using the site, wonderful..it was a great
4 years. If no such thing exists any longer, then we will have to roll our
own.
Finally, I'm actually getting excited by the possibilities of APRS Map
Manager!
Don't want to start an argument, just stating my opinion...

Well, there is no need to worry anyhow. I misread the access log. It
appears wlandb has accounted for about 200 accesses in the last two days,
not the 20 thousand I mis-read. That's a far cry less than findu's 194,471
maps in the last two days.
So to add to the linux stability thread from last night. maps.aprsworld.net
is an old Pentium III running linux. It is serving multiple maps per
second, running > 50% CPU load and is perfectly stable. On top of the maps
it is also running javAPRSsrvr for aprsworld and the archive.aprsworld.net
system.

Standard PL messaging Signaling 10 Feb 2004
-----------------------------------------------
WB4APR
This is a definition of standard meanings to PL tones that can be used by
alphanumeric HT's to display messages based on PL tones. I call it PLEASY
mode, for PL-EASY. No, such a thing doesn't exist, but it is ONLY a
software mod to radio hardware that can already to PL scanning on receipt.
So rather than having some marketing guy in Japan invent something less
than useful, let's figure out what are the 48 best definitions for HAM
radio short text identification/messaging for using these tones, then ask
YeaComWood to add it to the next firmware...
In other words, you and a friend or a special event, or even kids in class,
can signal each other silently by setting PLEASY mode and dialing in words
and keying the radio.
Here are some ideas:
OFF DUTY, ENROUTE, RETURNING, COMMITTED, SPECIAL, PRIORITY, GET ME, CALL
ME, PHONE ME, CALL HOME, WAITING, COME HERE NOW, IN 1 HR, IN 2 HRS, IN 3
HRS, LATER, REVERSE, ON SAR, CYCLING, SKYWARN, BOATING, HIKING, SKIING,
FLYING, HUNTING EVENT, RUNNING, EOC, ARES, RACES, ARRL, AMSAT, SKYWARN, CQ
CQ CQ, DXING, ROVING SSTV, ATV, APRS, ON-LINE, ON-MAINS, BUSY, UNAVAIL,
88's, KIDS-YOUTH, ADULTS, DOWN/BELOW, UP/ABOVE
If you have better ones, tell me which ones to leave out..?
I attempted to assign a few of the obvious ones:

If we define the auto-QSY protocol proeprly, ANY rig with a serial control
interface can then be used with a PIC processor to do all kinds of things.
1) QSY on command when someone wants to talk to you on IRLP/ILINK
2) QSY when a satellite is in view
3) QSY to do a sig check for the DF application we are discussing
4) Add local Channels to a memory bank when a mobile enteres a new
area.
5) QSY to the talk-in channel for any special event, etc...
6) QSY as commanded by net control for any applications...

You think so?
What happens when all the folks that where freeloading off MapBlast, who no
longer can do that, now start using your system and bring it to its knees?
We where told amateur radio generated 6 million hits a month to that. There
is a whole world out their besides amateur radio, and they would love free
maps as well.
An authentication protocol might be a good thing to keep in the back of
your mind as things progress. The good thing here, with this thing being
open source, anyone should be able to set their own up, but I can see a
good site getting overwhelmed.
