The GPSr's antenna is already encased in plastic so a additional 3 mil polyethylene baggie won't harm the signal, but I wouldn't use an antistatic metallized PET bag because it acts as a Faraday cage. Plastic bag, rough handling, waterproof, electronics, good luck.

I have the same login issue whether I use Foxfire 12.0 or Internet Explorer 8.0. All my other web sites are retaining their passwords, so I guess it's not a browser problem. That only leaves, now let's see, oh yeah, Groundspeak.

Kinnikuman and yakiimo, a dangerous combination, ne? Thanks for the interesting article. Another Carrington event, another DNF! Oh, well.

I was curious to see what the recent projected solar flares and CME would have on my gps. I set my PN-40's tracking interval to ten seconds and placed it on my window sill over night. The next morning I had almost 3,000 data points and the track showed the usual "rat's nest" of lines with a few outliers. I then downloaded the tracks onto Excel and calculated each point's distances from a central datum. The chart below is the result. As you can see there was one large excursion in the middle of the night. Was this evidence of solar influence? I decided to take a look at the projected DOP for that same time period using Trimble's Planning Software and I found a high DOP value around the same time period. It appears that satellite position and not solar activity caused the excursion. The rest of the collected data appear to fall within the normal range of signal bounce.

This should be interesting. "The Communicators: Lightsquared Broadband Network Plan" will be airing on C-SPAN tonight at 6:30 ET

I don't think Melissa is a geocacher nor was she a local. Her story can be found here if you scroll down a bit: http://stevenbarley.net/2011/09/25/breaking-update-the-dodge-journey-east-has-been-found/ This is just one of her comments: "Melissa: I still haven’t been able to catch up on sleep. I left VA Friday night at 7, slept 2 hours before the car went live at noon, slept 7-8 hours in NH, drove to Maine, then drove back to VA. I got a 1 1/2 hour nap in before my 2 year old woke up." Regarding your new geocache idea. Have you tried this still unsolved hunt? The Canadian Club's Lake Placid hide http://www.hideacase.com/. I used topo maps, hiking/xcountry ski trail maps, and Google Earth to come up with a dozen likely search areas all of which have been loaded on my gps. Now it becomes a massive geocache hunt. I have to visit Whiteface before the first snows. BTW, if you like urban hides, another very entertaining hunt is We Lost Our Gold. http://welostourgold.com/. This hunt uses landmarks along with bus and subway routes to find. It's still hasn't been located. Don't know how a gps would help though.

I found this combo to work. All the hardware can be found at Home Depot.

Hi, I have been using the negative longitude. It's not hugely off. The location should be somewhere in Rhode Island, and Google Maps shows it just south of Block Island, in the water. I was hoping that the difference in WGS84 before and after the upgrade would be enough to put me on dry ground. Are you sure you have the correct decimal place for Latitude? N41 49.440 is the center of Providence, RI, but N41 4.944 is just south of Block Island.

A simple board with a few cleats nailed to it may do the trick. The base board can be held down with your foot. The cleats are only thick enough to grab the container's base. The container is wedged in place so that the un-screwing action of the lid increases the gripping power of the wedge. The angle of the wedge can accommodate several sizes of tubes. As for the re-winding of the logs, that's a toughie because the log's condition can vary so much. Have to think on that one some more.

A light rain, generally not a problem. However I did get caught out in the woods when a thunderstorm rolled in even though only rain was forecast. Believe me, there is nothing quite as humbling as being in a thunderstorm, huddled beneath swaying trees in 30-40 mph winds with bolts of lightning and loud cracks of thunder all around. When you feel the hairs on your arms standing up due to the storm induced static electricity, you begin to question the value of getting that last smiley. I remember saying to myself "Do you feel lucky, punk?"

I was able to open the hidden file using WinRAR 4.0 (32 bit) 1. Copy "test.jpg" to the Desktop 2. Change name to "test.zip" 3. Startup WinRAR and open "test.zip" 4. Open "blah.txt" Interesting. Winrar 3.51 will not open it. I'm curious, does blah.txt have any text in it? I created one of these files on my computer using Winzip and the copy command. Winzip would not open up the file, but when I viewed the jpg in a text editor, I could see the actual text of the zipped file, at the end of the file. Yep, there's quite a bit of text about the startup of Groundspeak. If you view the file with a NotePadII or a hex editor you will only see the title "blah.txt" and the Local file header 50 4B 03 04 which is the start of the compressed text and 50 4B 05 06 is the end of the directory. The numbers 50 4B (read backwards (little-endian numbers) are FK for FKzip.

I still have my first navigational device, a Tamaya MS-833. Accuracy was better than +/- 0.5 miles on a good day after 20 minutes of observations, sight reduction calculations, and plotting lines of position. On the plus side, no batteries! Now people complain if their GPS accuracy isn't less than +/- 10 feet.

I carry a highly sophisticated, precision engineered but slightly modified yogurt lid. Smooth and Creamy works the best.

Flame treating will not adversely affect the plasticizers because the surface quickly reverts back to its normal inert state. Generally clear food containers won't use UV inhibitors (carbon black) or fire retardants (boron) or any other additives due to costs except for a mold release agent and perhaps heat stabilizer (dishwasher safe). Keep in mind that plastics in general have a large coefficient of thermal expansion. Polypropylene at 0.00005 in/in/deg F and polyethylene at 0.00007 in/in/deg F. That means a 10" long container of PP that winters over can experience a 100 degree temperature swing or 100 degs x 10" x 0.00005 = 0.050" overall growth. Generally paints do not have the same cte and tend to crack over time. The thicker the paint coating the more likely it will crack. Any adhesive used should also take expansion in to consideration. A rigid adhesive like epoxy will be more likely to flake off than a flexible glue like rubber based contact cement or urethane based cement. Again, flame treating improves adhesion. Combine thermal expansion with the flexibility of plastic with its modulus (can be stretched and bent easily) with its inherent inert surface characteristics and it's a wonder anything sticks to it! The only absolute way to bond similar plastics together is by fusing the two. A hot plate welder or ultra-sonic welding will yield bonds that are 95% the strength of the parent material.

Polyethylene, polypropylene and most other plastics have inert surfaces with low surface tension. A drop of water placed on the surface will "bead up" meaning the water droplet would rather cling to itself than cling to the plastic surface because the droplet has a higher surface tension than the plastic. If the plastic's surface tension were higher than the water's then the water droplet would spread out and cling to the plastic. There are two common ways to break the chemical bonds and change the surface tension to allow for better paint adhesion. They are corona discharge and flame treatment. Assuming that few people own a plasma generator then flame treating is the next best option. A few quick passes with a gas flame over the surface of the container will break the surface bonds and temporarily improve the surface tension. I use a hand held propane fuel torch with a fan nozzle to pre-treat before painting. This treatment will not last very long so apply the paint as soon as possible. Don't over do it and melt the container, and don't spray paint with an open flame around. Using the paints mentioned above in the other replies and a good surface treatment should give you the best bond possible.

Here's how it's done. This is from the National Legal and Policy Center. The whole story can be read here: http://www.nlpc.org/stories/2011/03/01/will-fccs-political-favor-harbinger-hedge-fund-result-gps-interference "According to White House visitor access logs, on September 22, 2009, Mr. Falcone and LightSquared CEO Sanjiv Ahuja personally visited the White House and met with the Chief of Staff at the Office of Science and Technology Policy (OSTP).[10] One day later, the Harbinger/SkyTerra merger agreement was signed.[11] On September 30, 2009, one week after his September 2009 White House visit, Mr. Falcone contributed $30,400 to the DSCC -- the maximum legal individual contribution limit to a party committee. His wife, Lisa Falcone, contributed an additional $30,400 to the DSCC on the same day. (LightSquared's new CEO Sanjiv Ahuja also contributed $30,400 to the DNC in September of 2010).[12] Mr. Falcone's contributions to the DSCC were anomalous as, traditionally, Mr. Falcone was a much larger donor to the Republican Party. In fact, just prior to the $60,800 in contributions to the Democrats, the most Mr. Falcone and his spouse previously contributed during that political cycle was $2,400. As for Sanjiv Ahuja, his $30,400 contribution to the DNC was his first political contribution in 8 years, and prior to that he contributed only to Republicans between 1998-2002. On January 21, 2010, Mr. Falcone visited the White House again, this time for an appointment with John Holdren, the Director of the Office of Science and Technology Policy." "In addition to well-timed political contributions to the DSCC at the height of merger review discussions, Mr. Falcone's Harbinger also secured the assistance of a lobbying firm, the Palmetto Group, via Harbinger's legal counsel Goldberg, Godles, Wiener and Wright to lobby Congress and the FCC on mobile satellite services.[13] Mr. Steve Glaze, a lobbyist with the Palmetto Group, was registered to lobby the FCC directly on mobile satellite services and is married to Terri Glaze, a senior staffer at the FCC."

I been using the same screen protector that originally came in the box with the PN40. Its seen over two years of use and 2,500+ caches. It's still good plus I have the second of the pair as backup. Save your money and wait, IMO.

Place the gps on the ground, standing on end. Measure the length of it's shadow. Now measure the length of the tree's shadow. The ratio will be the same. Tree Height = (GPS Height X Tree Shadow) / GPS Shadow

Do these ‘Bot’ accounts register as Premium or Basic accounts? I suspect they are probably Basic. If so, it may be time to limit Basic members to 20 logs per day while premium accounts remain unchanged. It’s regrettable, but when one maladjusted individual can affect on so many others through selfish maliciousness it may be necessary.

Consider the date of that report...2004. I'm sure if there was a problem it's been corrected. Last night, during the football game, I was watching the gps constellations on my PN-40. I did some screen shots at 23:00, 23:30 and 00:00 hours and compared them to Trimble's predictions using their latest (9/2/2010) almanac on their software. If you look at sats G15, G21 and G26 at 00:00 hours on both the PN-40 and the skyplot they look much the same.

A container that can keep water out usually can keep water in. So anyone who opens any type of container that’s been underwater will more than likely drip water inside where is bound to stay and cause trouble. The best underwater cache I’ve seen is a multi-cache, where part 1 is just a metal tag with the final’s coordinates stamped on it. Something along the lines of this one: http: http://coord.info/GC1YA42
