Yes and no.
I will ccertainly keep my official version and will welcome
mods (but only if -described- so that I can add them myself).
I cannot accept code that I cannot trace the changes in.
I also dont have time to track lots of changes.
So I woiuld encourage anyone that is planning on improving the code to keep
EXCELLENT change notes if they want me to add it...

Bob, you going to place a plot of the course on the web page? Would be
good information.
ANS: Yes, but I dont currently know how. I know it is trivial from FINDU.
Would you mind doing one for me and sending me the map so I can update my
WEB page?
thanks...

<I realized that more-than-one just gives more potential for errors and

place.... Bob>
In case you didn't realize it, what I suggested ahould NOT give you
"clusters all over the place". I just told two programs (one mapping, one
charting/nav) to "go to 99N 180W" and they both barfed and told me the
numbers couldn't be used.
And that's precisely my point, that there is a valid range of "imaginary
numbers" that exceed conventional lat/lon positions. A GPS or other
navigation instrument would never supply imput in excess of 180d longitude
or 90d latitude. But there are more digits available, i.e. up to 999d lon
and 99d lat can be passed through the APRS system with the same numbers of
digits. When they hit a computer, it can easily parse them out and say
"Ahah, imaginary numbers. I should use the XYZ private location for this
display."
Similar to the private IP address ranges on the internet, there would never
be "clusters all over the place" since no mapping software should be
mapping ANY of these addresses--unless you tell it where and how, and which
one(s) to ignore or use. That would allow multiple users, in the same radio
area, without any interference or confusion. You could display "this
operation" in one range, "that operation" in another, etc, and have the
option to turn each group on/off by simply using the bogus lat/lon numbers
like private IP ranges, telling your computer "OK, just show me this/these
now". Meanwhile, the offsets that everyone uses are in common.

Yes, sorry, that was a change a few years back. APRSdos now re-starts with
what ever VIEW was on the screen when you save a BACKUP file. So when you
FILE-QUIT the program, select "B" inorder to force it to save a BACKUP.BK
file instead of the normal time-stamped file name...
Or at any time, do a FILE-SAVE "B"...

Next time your APRS mobile is tanking up at the cheap gas station, give a
tip to your fellow APRS mobiles!
Simply go to the MENU and temproarily change your call to 186GAS. Then
send out a few posits and then change it back.
Everyone else will get a nice "180GAS" on their front panels. and their
radios then show them the DISTANCE and DIRECTION to the $1.86 gas.
Why not. You'r just sitting there waiting for the gas to fill up...

The Ferrite chokes on the TH-D7 data cable are there for a reason!
I built two brief-case APRS systems into two briefcases with external BNC
connector so an antenna could go on the LID when the case was in normal
use.
The systems were DEAF as posts.
Adding an external antenna at least 6 feet or more away did MUCH better.
Now I realized that I used home-made custom data cables instead of the
Kenwood RF choked cables.
By the way, the Radio looked normal. No on-channel RF at all, But just a
raised noise floor apparently that is undetectible by ear and undetectible
by the built-in S-meter too.
So if you build portable systems, rememebr you MUST get the antenna away
from the laptops by a big distance or you ain't hearing what's out there...
I dont know how much of the interference is coming from the non choked data
cable and how much is just proximity to the laptop... dont have time to
test that one right now....

That's easy... it'd be about 1,500 miles due East of here. Nothing under
$2.39 in these parts.

Bob, try this link ... It uses the landsat USA map that Wes Johnston
recently sent me a link to. Gives a pretty good display of the flight
progress. Its set to look a last 20 days and the 480's may need to be
bo0sted to, say 720 if the flight goes to 30 days or more.

Wouldn't GAS186 be better? That way those that have the ability to filter
could look for all the GAS* objects. (and I wish I could find it for $1.86)
