Sure, how about a Palm type device(easier data entry than D7A) with
built in D7A, GPS AND a wireless lan or at least IR.

I had made that suggestion before from the post of the Ipaq with the radio
built-in that got posted here a while back. No one really went for it then
so what changed?

I don't know if this is usable or not, but yesterday I was in xxxxxxx
looking for a quick UPS. (I lost power 6 times yesterday as storms
swept through the area. None were longer than about 5 or 6 seconds,
but it played havoc with my laptop and trying to debug a project.)
I ran into a small display for $30 that plugs into the top of a printer.
The Lexmark I think. It was a small color LCD display billed as a
picture preview screen. The idea, I think, was that you can plug your
camera directly into the printer to print, you don't need to go through
your PC. And with this small screen, you can even see the photos
as a 'preview'.
Now, $30 for a small color LCD...
I can already think of a few neat APRS applications...

Im surprised the Ham community has not caught on to Bluetooth technology
yet.
I think that it would be a much smaller step to achieve if for example TH-D7
could be fitted with Bluetooth rather than the endless amount of cables
associated with it already.
There is already a Bluetooth enabled GPS.

Then you could use your Palm or PDA to display all information from radio
and GPS on apps like palm aprs. All together making APRS a truly "portable"
experience.
Surely the biggest thing APRS is missing at the moment is portable
convenience.
So my list would look like this.
1. GEO digi(s) to cover each continent.
2. Bluetooth enabled portable APRS gear like TH-D7
3. batteries that last 12 hours but weight 100 grams :)

I was going through the thought process of getting another GPS for APRS.
First I wanted a GPS engine say a GPS 25. Small , extrenal antenna. No
display, batteries were a concern. I would use the D-700 as the display.
Not much good for bushwalking tho. Then I looked at a GPS16 from GARMIN.
Compact, batteries were still a concern, but had an inbuilt antenna. Still
not much chop for bushwalking. Then I realised for an extra $20 you could
go to a basic GPS with display, batteries and Track memory. It just seemd
funny that I was thinking of making my own LCD display, track log and
battery tray, when for a mere $20 more I could have all the maths done for
me, with a neat display.
Funny how technology goes huh.
Anybody running gecko ? I think maybe etrex might be a goa, but i like my
ETA , which extrex does not have.
ideas ?

$400!!! 6 hours battery life! It seems to me we may be several years away
from this being practical. I would think it would be easier and cheaper to
just build the GPS into the HT. I expect we will see that before much longer.

This is why I made the comment on the other thread that I believe that
many/most/some/whatever number of clients and sysops are praising the
effort to have ports that do not spew the full APRS feed. Can you imagine
what would happen if we took the 200+ or so users off the Tier 2 network
now at this point in the game and put them on port 23/10152 full-feed
connections? Scary thought in my book. Thanks for listening.

Hi All,
The DeLorme Earthmate GPS units are now NMEA compliant (what ever
that means) but they seem to deed a specific "code" sequence to activate
the data stream.
Does anyone have or know of a program that can access a USB port
that is being used by another program and display the signals passing
through the port? (Also woul\d be handy for serial ports too.)
Then one could decipher the code needed by the Earthmate and plug it
into the APRS programs.

You're comparing apples to oranges - first you say you want a GPS for APRS
and then you say you want a GPS for bushwalking.
Well guess what? Two different applications. The shoes I wear around town
in the summer are very different from the shoes I wear when
backpacking. Both are made of leather, and both have Vibram soles. But
the shoes I wear around town are called boat moc's and the shoes I wear in
the forest are called hiking boots. The hiking boots cost about 30% more
than the shoes, which seems to be a bargain, because the boots probably
have twice the leather in them, a steel shank, and are much more
comfortable when walking long distances with 50 pounds of equipment
strapped to my back. I suppose I could wear hiking boots all the time,
but I'd look funny in bowling tournaments or at funerals/weddings... :)
