Anyone have any info on these units?
I realize they are rather old, but Magellan has nothing on their web
site.
They may have been specifically for military use, not sure.

Hi Scott,
I have had my D700 for a year now and have not had to do a power recycle
on it yet. I use it in my car and on several occasions it has been on for
over 72 hours straight. So, for my part I would call it reliable for my use.
I know that this isn't the same as using it 24 x 7 for months. But, from my
experience I would say it is as stable as anything else on the market.
73,
Dave N0EOP

Does anyone know where I can get a serial 2x20 or 2x16
LCD display so I can hook up to a basic stamp ?

Go to page 3 of the Specialized Communications manual. The Appendix list
will give you most of the major commands.
I would like to stress this is not a BBS but a PMS, or, as they refer to
it in the manual, a mailbox.

It has approximately 110 kb available for storing messages.
Although I have never used it before I did some tests with a fellow ham
and it worked well, at least after I set MYM. :-)
Will carry on testing to learn more about it.

Andrew-
I've used several displays from Matrix Orbital (www.matrixorbital.com).
Currently, I have an LCD2041 Wide Voltage/Extended Temperature model
installed in my truck to display information being sent out from one of the
radios. It's held up to years of vibration, temperature shift, etc.
Matrix also sells VFD displays (not to be confused with the Inverse
Blue/White backlight LCDs). The VFDs are nice, but keep in mind that they
also slowly dim throughout their life. IIRC, the time to half-brightness is
10,000 hours (sounds like forever, but that's only 416 days of runtime in a
constant-run environment). Things may have changed, however, as I haven't
looked at them extensively in a few years.

Well, the slick part about using a d700 in space is that everything could be
controlled from the serial port... and instead of one default mode like we
have with the kpc3's already in space, you could have 5 default modes. Of
course the downside is that you could only use 9k6 or 1k2 at a time...
unlike what we have in space now.

Do they make such a thing? Why not use a standard LCD with the on-board
Hitachi chip and the 4-bit parallel interface?

Hi All,
If you like in an area that only uses the WGS84 Datum (or your application
is happy with this output from our GPS), then don't read on. However if you
want to change your Datum, this may be of interest.
Having just spent some time trying to change the Datum on a SiRFstar GPS, I
have managed to establish the following, which I'm posting here for
everyone's benefit so you don't have to wade through the suppler
mis-information that I have had to endure!
To start with, I am talking about the units which are designed for
connecting to laptops, PDA's etc. and do not have their own display, just a
"mouse" sized pod containing the GPS and antenna and a serial cable output.
Don't assume the manufacturer of your GPS actually makes the core GPS
engine. Haicom, Holux, RoyalTek, u-Blox (+ many more) and many of the
dedicated in-car systems generally use SiRF, Evermore or the Amtel Antaris
GPS engines dressed up in their own packaging and "front end".
SiRFstar I
~~~~~~~~~~
Used in units such as the Haicom 201S, Holux GM-200 and earlier u-Blox.
The GPS itself does not contain multiple Datum parameters, instead they are
programmed from special data files by an external utility called SIRFPROG.
This utility is available from SiRF if you buy the development pack ($xxx
!!). I have found the Holux supplied it on the CD with the GM-200 but
everyone else seems to just supply the hardware only, assuming you will use
the WGS84 Datum and don't seem to know how to change it.
There is a lot of mis-information that a freely available utility called
SIRFDEMO is capable of setting up the Datum. It is not!
SiRFstar II
~~~~~~~~~~~
Used in units such as the Holux GM-210 and current u-Blox.
This unit does know about multiple Datum's and only needs to be told which
Datum code to use.
A utility called u-Center from u-Blox allows you to set the Datum code
(available from http://www.u-blox.com/, register and it's in the download
section). This utility also allows you to manipulate most parameters on the
SiRFStar I as well.
In conclusion, don't believe what suppliers or even the manufacturers tell
you (some of the mis-information I received came from Haicom themselves!)
and if you want anything else than a WSG84 output, avoid the SiRFStar I
engine due to the difficulty in obtaining the Datum programming stuff.
Jim

TO turn on the D700 BBS just send it the MBOD ON command and set the

Subject: APRS to Dayton

There is no better time for APRS than traveling to Dayton.
Here are some tips:
1) Keep your STATUS text updated with what VOICE repeater you are
using/monitoring. This is VERY valuable, but also since most people fail
to update it as they channel hop, it is rarely up to date. At least on
Dayton Weekend try to keep it up to date.
2) If you have a Kenwood, set VOICE ALERT. THis means turn up the volume
on the APRS channel but set PL100. You wont hear any packets, but anyone
within simplex can call you voice (PL-100) on 144.39! If you have a dumb
tracker, it can also do VOICE alert if its TNC is attached to the
discriminator (before the PL squelch). This is a FREE APRS only calling
channel.
3) Use DEAD RECKONING! LAPTOPS with Deadreckoning work best. That way
moving vehicles keep moving on your map and maintain their same relative
positions as they all move towards Dayton. Without Dead Reckoning, then
positions leapfrog and are always out of date. If they are near you, and
at a one minute rate, then they can be as much as a mile infront of you or
behind you whenever you look at the screen. You have no clue how to
rendezvous.
IF DR is on, then their posit keeps moving just like your vehicle does and
so you maintain the same relative positioning and it is easy to
rendezvous.
4) Use the MILE-MARK feature to add any non-APRS travelers to your map.
If you are talking to "joe" who says he is just passing mile mark 53, then
in APRS, just hit MM53 and APRSdos (at least) will mark that spot on the
map. Use your cursor to add "Joe" as an object there and give him a
course towards dayton and a speed of say 65 MPH, and now JOE will also
move on your map towards dayton. Minutes or hours later, his object will
still be moving and so it is easy to see how he is doing. Every now and
then when you hear him again on 52 or other repeater, comment on where you
"see" him and he will be AMAZED how you were tracking him with APRS.
Or he will say he is ahead or behind that and you can correct his moving
object.
5) When driving to Dayton, I usually am on about the 32 or even 64 mile
scale inorder to see everyone that I can usually be talking to on the
nearby repeaters. At this scale, The crudeness of APRSdos maps is not an
issue nor any concerns over dead reckoning errors. Even if you put
someone at 65 and he is only going 62, his position will only be a mile
off after 20 minutes. Certainly close enough for figuring out what
repeater, and communication ranges.. THe idea here with APRS is simply,
keeping track of your fellow travelers relative to you, simplex range, and
nearby repeaters, not looking a street level detail.
6) When you run across a WRECK or Traffic Jam, or anyother significant
item along the way (Maybe a cop car) put it on the map. Might be of
interest to others. If you have a Kenwood, configure one of the PM's
with the MYCALL of "SLOW-N" where N is a random number and using an ICON
of a TRIANGLE.. This way you can put a "SLOW-N" TRIANGLE object on the
map marrking any slow downs in traffic. The reason for the N's is so
that your's doesn't replace someone elses... Kill it 30 minutes later.
7) Have preloaded several "canned" messages. When you see someone new,
you can send one of these with just 2 simple key strokes (in APRSdos). S#
where # is the number of the message. Makes the first 2 or 3 lines of a
QSO go quickly and easily.
8) Set your path to RELAY,WIDE,WIDE enroute to dayton. Drop it to
WIDE once you are IN Dayton! Definately NEVER start with RELAY while
in dayton. Even consider NO HOPS in Dayton. There will be a dozen people
within 3 miles of you to see you anyway..
9) Run with DIGI ON in your kenwood ENROUTE TO DAYTON ONLY. You MUST turn
DIGI off when you get there! If you have a KPC-3 dumb tracker, set UIDIGI
to RELAY while traveling. But also TURN IT OFF When you get there.
10) Greather than 60 miles from Dayton, and moving, set a 1 minute rate.
Especially if you are in an area with no DIgis. You have to beacon
frequently for any decent chance of hitting another mobile. In a good
area with digi coverage, you should drop back to only 2 hops probably.
11) If you want to "read-the-mail" with your Kenwood, add the Asterix (*)
wildcard to your MESSAGE GROUPS and then you will capture everyone's
messages.
12) Play the game APRS FINDU. See next message.
de WB4APR, Bob
