Why don't you have a port people can test too ?
Gives a print out of what is wrong with the packet ?

Because there is no code that tells people what is wrong with a packet.
Computationally, this is a very hard problem, you need to have code robust
enough to deal with every possible bad paqcket people could throw at it. Far
more work than it is worth...

Hmmm... Findu puts the digi on the other side of the globe. Must be having
trouble with deciphering the perfectly good LAT/LON ;-) The packet is
obviously chopped off with what should have been on the end of the string.
The memory in the digi was corrupted. A quick remote reset of the digi put
it back into the originally programmed format.
W4GPS-7 was a simple case of needing to be reset since the RAM apparently
got a case of the hiccups.
Steve, thanks for posting the information. It certainly pointed out a
problem caused by the unknown. In the case of W4GPS-7, I suspect a
lightning storm or power glitch may have modified the programmed beacon.
Heck, it could have been when the 1,000 foot tower collapsed over there
causing more problems than a couple human deaths (a very unfortunate
accident).

There's nothing special about it.
The Digitraveller hardware outputs standard NMEA183 2.0 data that will work
with any mapping software that works with a standard NMEA 2.0 device.
The PC and "PDA" versions of the Digtraveller are identical -- only the
provided cables and bundled software are different.
The software bundled with the "PC version" of the Digitraveller is just the
current version of Delorme Street Atlas. This is the one known as
"Street Atlas 2003" with the sluggish clunky interface that is totally
useless for use with any APRS application.
The "PDA version" is bundled with Delorme "XMap Handheld" which is a
special version of Street Atlas for use with both Pocket PC and Palm
devices. You view the entire US (from a CD-ROM) on a full size PC with a
display that looks essentially identical to the normal SA 2003; then
download selected regions into your PDA.
The program running on the PDA then has many of the same features as the
full-sized PC version of SA: Zoomable and scrollable maps down to street
level, autopanning to follow the current GPS location, a GPS handler that
works through the PDA's serial port to lay down a "bread crumb" trail of
your course of travel, GPS skyview diagram, street name lookup and locate,
etc.

I have been in the process of updating the 16x16 icon set. The current
widely distributed set used by findu, APRSplus, APRSworld and the Xastir
website is at odds with the symbol set defined in the current "official"
APRS standard.
For example the symbol code defined as "SSTV" in the APRS document (which I
transmit all the time from my "SSTV mobile LiveCAM on my APRS beacon, and
which the Kenwood ''7s display correctly) shows up in all these places as a
thunder cloud which was reassigned to the secondary set according to the
APRS document.
As part of a project to create a 16x16 symbol set for use with UI-View (it
normally uses a 20x20 pixel symbol set created by it's author which IS
compatible with the current written standard), I have been updating and
correcting the 16x16 set. I am nearly finished creating 16x16 sets
formatted for UI-View and for APRSplus.
[ Both these apps use the all symbols laid out on a grid in a single BMP
file for the primary set and a second BMP file for the secondary set. Both
apps use some sort of indexing and counters to select the right 16x16 chunk
of this big picture each time a symbol is needed by the program. Each app
uses a different layout so I have had to do the painstaking cut and paste
operations in a graphics editor twice! ]
When I get back to LA in a week and a half I will post the results on my
website.

This is also echoing the incorrect assignment of the older symbol set --
Look at upper-case "T" which should be SSTV. It's also showing that
thundercloud!

Speaking of which, can anyone shed light on this one?
