I found a file (written in German!) on the Yahoo Mpasend group that explained it. As I don't understand German at all, translating just the few paragrahs I needed took over an hour
Here's my terse, English version:Take that set of 15 numbers and break them into 5 groups of 3. The first three are for the HIGHEST detail display, the next three for HIGH, then MEDIUM, etc..
For each detail setting, and each triplet of numbers, the FIRST number is the zoom level where OBJECTS in a layer becomes visible. The LAST number is the zoom level where the NAMES of the objects are first shown. The file I read said the purpose of the middle numebr still wasn't figured out.
I thought finding someone who had mozt of this worked out would save me time - now I wish I had studied German in school!

RE: http://www.dengoods.com/meridian/
Right, I already had that and it was a great help. But what I was looking for was more detail on what you could do with the various items in that config file.
For example, DenGood's customization sets all the road types to Dark_Grey intead of black, and turns off the STREETS layer for any mapview over the .4 mile size. But there's 15 pairs of numbers defined for each layer. I've found that these define at what zoom level and detail settings (highest, high, medium, low, lowest) an object and it's name become visible on the display, but I don't have all the details.
There are also some specifications for line styles and box fill types, but I'm not sure what all of the possibilities are or how they're applied. And I haven't a clue how the [GROUPS] or [POI] section work, or how I might be able to modify it.
I was hoping someone already had more of this figured out, which would make my own experimenting/hacking go a lot faster.

In the Yahoo groups related to the SporTrk and the Merdian units, I've found some limited notes on how to customize the Export.cfg file to improve contrast on the GPS display, and also to alter the copyright notice for the Topo data that is displayed on one of the startup screens.
Does anyone have MORE detailed information on hacking that export.cfg file? I'd really like to dig more into what migyht be done with that [LAYERS] section, but if anyone else has details of how it works it would save me a lot of time experimenting.

Wrong
The Mac OS lacks many of the security holes that make PC's such powerful incubators for viruses.It may not be bullet-proof, but it's better than anything else out there.

Does anyone know what is new in 4.04 versus 4.03? Is there anyway to get 4.04 except waiting until Magellan posts it on their site?
4.0.6 is now on Magellan's site.

Matt, when did you order your GPS and when did you get it?
I looked for the vendor and the auctions you mentioned, didn't find an exact match. I did find one vendor that looked like the one you found with some past auctions of SporTrak Pro at great prices...
BUT -- The auction listings read like an article entitled How To Spot An eBay Scam.
AND -- There are no current auctions by that seller.
AND -- It looks like eBay has suspended the vendor's account/store.
Either I found the wrong vendor, or there's more to the story here.

After looking at stickers, buttons, hats, t-shirt and the like, I've been thinking about an obvious bit of licensed gear that nobody seems to have yet.
Why not cache containers?
I know everyone loves ammo boxes. But would there be any interest in a well made, lightweight and weatherproof plastic box?
I'm thinking initially it should be a single, subdued color with a matte finish, and the word GEOCACHE embossed on it. Ideally though, it could be painted any color scheme.
Is there already a licensed product like this that I missed?
Would anyone be willing to pay a little more than an ammo box for a "licensed product?"
Are there any features you would want in the ideal cache container, something that you just can do with an ammo box or a Tupperware?

Yup, I read that when I logged the find -- but I don't nderstand how the marks so close together are used?

Well, that is a puzzle then. They're about twelve feet apart, in a line parallel to the road. The markings are no help to me: The north one is simply marked "44018" and the other "44018 No. 2"

Y'know, I had no intention of boasting about how I bicycled 108 miles today. But I found a benchmark(NE1298) today without even trying, so I thought it was worth mentioning. A very odd story in itself.
I was around mile 95 of my ride, when I came to a police road-block. There had been an accident on the road ahead, and they had it closed off so wreckers could remove the vehicles. The police were directing people to a detour that would have taken me about 5 miles out of my way.
The extra distance wouldn't have bothered me. But I knew the detour route included a terribly rutted dirt road. So I turned off, went a few blocks along the detour, then came back along trails to the main road. This shorter detour accessible to pedestrians and bicycles would not have worked for a car, but it did take me well past the accident scene. The only reason the police were detouring everyone so far out of the way is that the accident occured in a long stretch of nothingness -- no other cross streets for cars to use to get back on track.
I now had a several miles of this "closed" main road to myself, and could dally as I liked. Around mile 98, I stopped to drink some water and noticed two witness posts next to each other,; sure enough there were Michigan Department Of Transportation disks in the ground there. I marked the waypoint and looked it up when I got home.
I haven't seen two disks that close together before. Anyone know why that was done?

Maybe off-topic, but remember to keep your inventory (as well as up to date back-ups of all important data) off-site.
I keep my backups here

Unless it's gonna save lots of money and time, I don't bother with a soldering iron.
If I understood from your other thread, you're talking about static testing, plugged in and not going anywhere, right? In that case I would just clip or wrap wires into the battery compartment, temporarily. Might be tricky with the funny battery carrier the ST uses, but not impossible.
You'd want 3v there, not 12v. You can get a 3v adapter pretty cheap at KMart, Wal*Mart, lots of places.
This would also leave your data port free on the back of the GPS. I don't know if there's any way to simultaneously use the power & data functions of the external connector.

I dunno if I would buy it on eBay, but you could download the demo from the author and see if it's any good. Guessing from his webpage layout though, I wouldn't expect much.
Anyone know Robert W. Benjamin by a handle in any geocachng/Groundspeak forums? It might not be his auction on eBay, but some rip-off artist.

That may be, but the Magellan shows two sats on sreen. The one it always gets is AOR-W, the other is lower and further east than the other so I assume it is AOR-E.
Whether or not it uses any data -- from either of them -- at any given time is a mystery to me :-)

Ooh, I could Markwell this, but I'll just re-iterate something I wrote in another thread last night.
Like RogBarn, I downloaded datasheet archives for my county and several near me in southeastern Michigan. Then I wrote a short program to scan for MONUMENTED and FIRST OBSERVED dates.
Out of around 1300 benchmarks, I only found 8 dated before 1900, and 11 from 1900-1909.
I live in Oakland County, which is landlocked, but it borders St Clair, Macomb, and Wayne counties, which border major waterways. ALL of the older benchmarks I found were for lighthouses or other shoreline landmarks.
No antique benchmark hunting for me, I guess.

Originally posted by Kerry:From Lake Michigan (if that's anywhere near you?) AOR-W is around 28 odd degrees above the horizon and dropping as one moves west.
Well, Lake Michigan is nearer to me than any points in Oz, but it's on the other side of the state :-) I'm about half a degree north of downtown Detroit.
My GPS almost always shows one WAAS sat (ADR-W), sometimes two (second being ADR-E?). And according to maps on this page there are ground stations near enough to me that I should be able to get valid corrections.
Since I live in an area where WAAS should have at least some usefullness, I was really more concerned with HOW MUCH usefulness and also the impact on battery life. Since every unit varies, I think the only way I'll be able to find out is to run with it off for a while and see if I can notice a difference.

Like real estate and geocaching, WAAS reception has a lot to do with location. At least from what I read here
I guess when I asked for some some real world examples, I should have asked for something closer to home. I understand why WAAS wouldn't work in Australia, still not sure if it's a worhtwhile proposition in southeastern Michigan, USA.

Just the facts, please...
I've been following this and other WAAS threads and I'm finding lots of opinions.
Does anyone have some emprical data to share? I'd be interested in some tables showing battery life in a specific GPS unit with WAAS on versus off, and some real-world comparisons of accuracy in the same units with it on or off.
Does anyone know where I could find this kind of data?

Verily! I just downloaded datasheets for my county and seven adjacent ones. I was looking for benchmarks placed in the 1800's, or nineteen-oh-anything.
Out of over 1300 datasheets, I only found 19 monumented prior to 1910. None in my landlocked county of Oakland -- most of the ones I found are for shoreline landmarks, like lighthouses.

Need extended battery life -- 15 hours+
in GPS technology and devices
Posted
I usually put NiMH rechargeable batteries in my SporTrak Pro. I get about 9-10 hours on a charge, and always have a charged set ready to swap when needed.
However, I now have a need for much longer battery life. I've started using the GPS on my bicycle, and I analyze track logs after a ride for performance evaluation. For an accurate track log and maximum and average speeds, the power has to stay on for the whole ride (even during stops). A day-long trip might be 150-200 miles, so I need the GPS to run on batteries for at least 15 hours and maybe more.
Has anyone experimented with lithium camera batteries? Any idea how much life I might get out of a pair? I expect most geocachers and casual users wouldn't bother with lithium cells, because these batteries wouldn't be cost effective for routine use. But if anyone has tried them, please let me know how well they worked for you.
My alternative might be to build a battery pack of higher capacity, and attach it to the external power connector. That would be clumsy for hiking or any handheld use, but not really a problem on the bike -- but it still seems inelegant.
Suggestions please?
