I agree that this is pricey. Add this up...
    TinyTrak unit $30
    Trimble receiver $50
    Antenna $50

A complete APRS for less than 1/2 the price and much smaller!

OK, if I tell you I used the wrong word, but you understand what I am
talking about, will that satisfy you? You seem to understand the concept,
so I don't know what all the rest of the chest beating is about.

OK... tell me why it is not feasible. Who is this "us" anyways?  I'm just 
speaking for myself here, so if you could clarify what body you are speaking 
for, that might be helpful.

Oh ya,  what does "brow beating" mean? I've heard this slang before, I
assume it has something to do with a person trying to make their point and
the other person doesn't like the point and/or has heard it too much, but
did the root term "brow beating" really come from someone getting beat up
around the brow? I can picture the term "you sound like a broken record" as
maybe a analogy of what you are trying to say, but brow beating and your
term "us" makes a mental picture of lining up the entire SIG, taking a 2000
foot 2x4, and then me swinging it and hitting everyone square in the
brow....  

Well, it made me laugh.... ;-)

Sean, its not my "stuff". Distributed file systems, redundant files systems, 
its all part of industry practice. At one time it was even being used on the 
APRS-IS by rotating DNS/IP names users connected to. I'm just suggesting the 
same for the map servers. 

This is really tedious... one can't suggest one way to improve the system 
without many getting all defensive. It must be like walking on eggshells to 
your boss at work if he/she suggest a alternate way.

>Until then, don't tell us how to build the network. 

I'm not telling "us" how to do anything. I wasn't even talking to you. Or is 
"us" one of your other groups you represent? 

>You've made your point.  You can argue

I wasn't talking about anything half-baked. I was suggesting that "free" 
always comes at a cost, and better to design a system to lessen its impact. 
One way to do this is distributed load sharing, be it files or whatnot.

Sean, you, we, us or them are free to do whatever you/us/them/we want. As you 
said, I made my point. It is possible to disagree about something, although 
for the life of me, I don't know what it is.

Speaking of fancy cases, has anyone here use
http://www.frontpanelexpress.com?  Their CAD program looks pretty easy.  I
looked up the specs on a standard Hammond extruded aluminum case and used
that as a template to build a quick mock-up of a front panel for a tracker,
with appropriate holes and lettering and such.  The build-in price
calculator put it at about $18.  Seems fairly reasonable for a one-off
thing, but I don't think I'd want to do that for any large production
quantity!

Scott,

I used front panel express last winter for a couple of prototypes. Very nice 
look and I recieved the parts two days later. Cad software was very easy to 
use, despite it not being entirely translated from German yet.

Now I have my own vertical milling machine, so I do most stuff myself. :-)

Another excellent service is Filener Laser, http://www.filener.com/. Just send 
Bruce your autocad drawing and a couple days later you get a plastic piece 
back for a few bucks. He's even willing to accept hand drawings or 
descriptions for simple parts. Bruce produces the front panels for my wind 
speed dataloggers and he does an excellent job. (tell him I sent you).

PLEASE no one do that. I am sure by now they know that we are using it
but just in case it is best to keep low key. If there is any possibility
that they are just down for repairs or upgrades and we throw a flag up
it may cause other problems.

Old mail indeed <g>. I think Pete covered this very well. I didn't want to 
write a book on how it was necessary for an APRS station to send position 
reports.

What's interesting is... if you never send a position report we can't 
invent one... can we? I think what was going on 'back then' was a station 
that was attempting to send messages and never got ack's. He forgot to 
enter a position in his software, and his zero position or lack of one, put 
him southeast of SEKONDI-TAKORADI, GHANA. At least, that's where findU 
found him.

>Wim

Anyway, he fixed it and all went well for him. APRS works so much better if 
you send a valid position, sometimes.

Next. There's a lot of software out there that that look at 'local' 
differently. I think it's safe to say that if an Igate hears a station 
direct, it is local. However, change that to several hops by telling your 
software that stations heard over 5 hops are local, creates a different 
situation. Especially, if an IGates' unproto path can't reach them. You'll 
attempt to RF them and it won't ever work, unless the Igates' path is 
capable of reaching out 5 hops on RF. Sorry if I opened a can of worms... 
but, there are many mis-configured Igates sending needless traffic to RF 
trying to reach stations beyond their local Igate coverage areas.

Tell us Bob/Steve, what should be considered local for an Igate?

Hello to the group. I have a simple question that I hope can be resolved
here. If I have a group of objects that I have generated; how can I save
them so if I shut down and restart I don't lose them and have to regenerate
them?

Thanks

Yeah, that's the way.  Skulk around like a thief in the night.

What would it hurt to ask mapblast what happened, or ask them for privs to
use their maps. Especially since amateur radio here in the states seems to
be part of the latest "home security" contingent.

The author of Radio Mobile, VE2DBE, didn't take any time to produce a new
version that points to mappoint.  Understand I am not saying findu
author(s) are at fault; it just amazes me someone would suggest a covert
action.  Nor am I saying mappoint maps are good; it is the suggestion of
denial that gets me.

Seems to me that if you want to keep the frequencies and make a better
presence you'd stick your head up once in a while.

That's just my 0.02 for the day.  Means as much as trying to convince
someone that new APRS users need training on paths.
