A quick look indicates no. Looks like bootp/tftp or internal disk are
your options. There is a flash option, but couldn't see where you could
boot from it. You can reprogram the FlashPROM, good luck...

I just picked up my DigiTravelers, so I tried hooking it up to the PC in
the house. I can't get any sats to let it lock up.
So I tried another of the DigiTravelers. (I got 3) Same. Do I tried my
GPSII+ and GPS3. It's the house!
So, I figured I'd go outside.
The cable I made for the PC used an RJ-11 6P6C and I hooked up as 2 3 5 on
the RJ to pins 2 3 5 on a DB-9F, with 7-8 and 4-6 tied together. I
evidently find the GPS, but I just acquire forever.
So, I made up a similar cable but with a DB-9M to tie to my Palm HotSync
cable. And I swapped pins 2 and 3 when I tied to the DB9.
I can turn on the GPS when I tap on XMapHH but it always says it can't find
the GPS. With 2 of the units. Is that just that it's not getting a good
lock? Time to step outside...

My Ipaq install defaulted to a delorme gps, not radioshack, had to change
and then it powered and locked right up...

That's what it was here too. It didn't default to the DigiTraveler, so it
said there was nothing attached. Once it was set right, then I could see
the data packets going by on the skyscreen. It took a while to lock, but
once it did, it was fine.
I found out RS has an update for the XMapHH software on their web site at
http://support.radioshack.com/soft.htm but it's slow and freezes up a lot!
I'm STILL trying to get it downloaded!

I haven't cracked any of my DigiTravelers open yet, but it appears from
looking at your photo that there already was a provision for power on
the cable. There's a fuse on pin 1, or a least a position for one.
And what's connected to pin 4, and pin 6 of the RJ?
1 - +power
2 - TxDat
3 - RxDat
4 - ???
5 - Ground
6 - ???
I think in my case I'm going to build a my cable so that it sends +12v
up pin 1 on the cable to the unit, and I'll put a 78L05 inside the thing.
Then outboard where my cable meets, I'll put another 7805 to charge
and power my Palm...
Maybe I'll make a cradle and build everything in that, then just have a
single wire up to the GPS...

Well, they ARE, and they will. I am not disputing the validity of your
suggestions Bob. However, looking at your FIXING THE 144.39 NETWORK WEB
page the first sentence reads "The most important thing we need is USER
EDUCATION..."
You seem to know the root of the problem. Question is, if they are not
informed, or are unwilling to abide by convention, then what is to prevent
them from using silly paths; including those Ev suggested? Nothing is
being "enforced".
"They MUST NOT BE DOING THAT ON APRS" is a valid statement. And it does
nothing to address the cause of the problem - uneducated or irresponsible
users. How do you suggest we educate the user?
If you need a starting point: Make the APRS docs READILY available, if
they aren't already, and get the word out as to where they can be found.
This means, do not expect people to look in APRSDOS txt files. (I had a
heck of a time finding the docs when first using APRS; and wonder how many
others had/have the same problem. It was easier finding info on how to use
APRS software, and that is pretty slim in some cases. No offense to you
folks who put so much time and effort into programming APRS software, I
dislike doing docs myself ;)
Best to all,
Vince

Thanks for echoing this Steve. Sooner or later folks will realize that
once in a while the industry recognizes the value of standards, and
implements them. It's interesting that this one has been being included
in radios for about 10 years - I definitely recall reviewing it for
interoperability with our stuff when I worked at AEA. And it's been 9.5
years since then...

Hi Bob,
What XXXn-N misses is the human factor. Why is WIDE7-7 a problem? Not
because of WIDEn-N technology, but because 7-7 is "bigger" than "2-2", so
"it must be better". The problem isn't the network, it's uneducated
people.
As soon as word leaks out that WIDE,WIDE is good in the XXXn-N paradigm,
someone will figure that "WIDE,WIDE,WIDE,WIDE,WIDE,WIDE,WIDE" is bigger and
better, too. XXXn-N lanning doesn't firewall this potentially
geometrically bigger problem.
Bob...APRS has all of the right infrastructure already in existance...ready
to be exploited to help keep people educated automatically:
1. We have APRS messaging.
2. We have TRACEn-N.
What we need is "APRSteward". It's an idea to have the LAN monitored
automatically and have UNPROTO's analyzed in real-time. Each local lan can
determine what it's own pain threashold is (NM=TRACE6-6, So.Cal=TRACE2-2,
etc). If/when it is exceeded, then it sends an APRS message to the
offending station to inform them what the acceptible UNPROTO is for the
area.
How simple! Newcomers to the area can be informed what the local lan is
all about! This is what APRS has been waiting for! No more guesswork.
Nothing is broken.
The trick is to determine how the rules of the local LAN are entered into
the system so as to not have it send messages in error. What I'm
describing is an APRS version of a SPAM filter! It works because the SPAM
is fully tracable back to the originator!
Think about this...it's really a cool idea!
Ev,W2EV
