  1. Perhaps the idea of this forum is to promote APRS for geocaching? With inexpensive cm level GNSS positioning available now, we need something to spice up the challenge.
  2. Again, this is the arrangement I use in my vehicle with a Kenwood TM-D710G mobile, to see the APRS stations around me on my Garmin Oregon 650T. This solution also works with the Kenwood TH-D72 handheld. Unfortunately, the newer Kenwood TH-D74 has lost the 2.5mm GPS port, but offers USB and Bluetooth.
  3. Unfortunately the only solution I am aware of is to use a Garmin Serial Data/Power Cable with a RS232 Serial-to-Bluetooth adapter, then to link the TH-D74 to the Bluetooth adapter. Depending on the Bluetooth adapter, this isn't straight forward to configure and the Garmin interface cable requires external power. What a mess.
  4. I'm not clear what you are trying to say. I want to see the received APRS Station (Waypoint) data on the map display of an external GPS. Why do you say they don't need external connections to do this?
  5. Just a few ideas: Incorporate morse code Incorporate Q-codes into clues? (QRJ, QRV, QRZ, QSS, QST, QTH, QUC) Use resistor colour codes to write out coordinates (Apparently the mnemonic I was taught to remember the colour codes is not politically correct.) Clues where each cache in the series identifies a component for a simple circuit, and cacher has to email you a correct answer to be able to log success? (Maybe the web page for the cache has a "fill in the blanks" schematic. It could be a block diagram to make it more easier, and the "components" could be "Mixer", "VFO", "RF Filter", etc.) Beacon the first cache location as an object with APRS (from your home or club APRS node) (aprs.fi could be referenced for people without APRS radios.) https://www.socialhams.net/m/documents/view/socialhams-APRSCaching
  6. For many years I have been using an Oregon 300 with a Kenwood TH-D72 handheld and Kenwood TM-D710A mobile. I have been using the Garmin Serial Data/Power Cable to interface the GPS to the radios 2.5mm GPS port. Recently I have added a Kenwood TH-D74 handheld to my collection, and my Oregon 300 came to a bad end. My new handheld is a Oregon 650T (Canada). Trouble is, the TH-D74 has bluetooth, which has proven to be very cool, however the radio does not have the 2.5mm jack like the TH-D72 has, for interfacing to a GPS. The Oregon 650T does have bluetooth, however this appears to only be usable for exchanging data between compatible Garmin GPS devices and connecting to a mobile app version of "Basecamp Mobile" that no longer seems to be available. There does not appear to be Bluetooth serial port profile (SPP) support on the GPS for exchanging NMEA data over bluetooth. I have sent a request to Garmin about enabling SPP on the GPS, but have not received any response. Does anyone have a suggestion for interfacing the Kenwood TH-D74 handheld with a Garmin Oregon 600 series GPS?
  7. Let alone HAMS, how about time-nuts? Trimble Thunderbolt GPSDO anyone? Placed out first cache in July, 2002. VE7JMR Garmin GPS II+ -> Garmin GPS V -> Garmin Oregon 300 -> NVS NV08C-CSM + G5Ant-52AT1 + Nexus 4 + RtkGps
  8. For users who travel outside of North America, what are the DeLormes street navigation and topo maps like? Thanks.
  9. Batteries like the Sanyo Eneloop, the new Sonys, and some other brands of NiMH do have good shelf-life. Perhaps not 5 years, but if you charged these new NiMH batteries up and put them on a shelf, 1 year later they will have 85% of their charge available.
  10. I have one of those iSun 2.2 watt solar chargers. (Not sure how nice it is to the batteries.) When we're out camping, I can fully charge a set of 4x AA 2,000mAh batteries in under 7 hours. LIMITLESS POWER!!!
  11. I'm getting ready to buy a charger..Do you like that charger which is one on my list plus the Maha C-9000 Unfortunately I have no experience with the Maha chargers, but for my AA and AAA charging needs, this LaCrosse is pretty nice. I just wanted a smart charger that would not over-charge or overheat my batteries, could condition them once in a while, and to have the option to quick charge (~500 - 1200ma) if necessary. (Not something I'm keen to do, but flashes at events like weddings, tend to be thirsty. I'll never do enough ongoing flash work to justify an external battery pack.) I have a GPS V at present (I love the feature of changing the screen orientation to switch between auto and trail use), and the Sanyo Eneloops are good for at least 14 hours. I've been thinking about getting a 60/76CSx or the new Colorado, but it appears Garmin has some revision to do with this new unit. The Colorado looks promising, but my GPS V is bug free so a new GPS should work just as well, with more contemporary features. My main complaint with the GPS V is that with newer versions of City Navigator, such as version 8, routing has become very slow. If you miss a turn, you might as well pull-over while the GPS V tries to update the route. It wasn't like this with older versions of the maps. I appreciate that Garmin wants to sell me a GPS for the trail and a seperate GPS for my car, but I'm not made of money. It's too bad the Colorado doesn't include voice prompt capabilities for auto navigation.
  12. These guys seem to have a good selection of quality NiMH chargers: http://www.thomas-distributing.com/nimh_battery_chargers.htm I'm providing the link as I had a tough time finding a source for a good battery charger. I'm using a LaCrosse BC-900 these days.
  13. The Colorado seems an excellent example of what I'm suggesting. Why isn't this product designed to say on the box? "For use with 2x 1.2v AA rechargable batteries recommended. 2x 1.5v optional." It's too bad that designers are still designing around 3.0volts, instead of 2.4volts. I have a bunch of the 2500mAh Energizers, but they don't seem to hold a charge. Having more recently purchased some of the Sanyo Eneloops, they definitely seem to be the way to go.
  14. We need someone with a car adapter and a multimeter. It would be informative to measure the current drain of the Colorado with various backlight settings, from none to highest. apersson850: Would you by any chance have the car adapter and a multimeter? :-)
  15. Apologies in advance, but you know, you're really leaving the door wide open here for am off-colour innuendo. Something to do with "body temperature" comes to mind...
  16. After reading some discussions about the new Garmin Colorado and older 60C(s)x, it appears they do not meter battery status correctly with NiMH batteries. Why is it that everybody involved in the electronics industry, from government regulators to manufactures to consumers, do not insist that portable electronics are designed for use with rechargeable batteries, such as NiMH, as their primary battery type? Why do we still live on a planet that expects 1.5volt Alkaline AAs to be the standard for small portable electronics? When there are NiMH batteries that have 85% of their charge after 1 year on the shelf and can be purchased ready to use (Sanyo Eneloops for example), what reason can there be for non-rechargeable batteries any more? It just seems irresponsible to use disposable batteries when rechargeable technology is so mature. Look forward to your feedback. Where’s Team DeLorme?
  17. This is not intended to be condescending in any way, but have you tried changing the batteries? With a GPS it's hard to know when it's really working verses patiently updating the display so gauging when battery draw is peaking is difficult. Does it crash sooner with the backlight on?
  18. So far this thread is suggesting that there may be some inconsitence on how Colorado's deal with external power on the USB mini-B port. This is a little alarming. I must confess, I am happy that Garmin is offering an RS232 cable for the Colorado. I was a bit worried about how I might met NMEA sentences into my telescope's computer without an RS232 interface on the GPS.
  19. Hmm, this seems a bit anti-competative. I don't have to use a RIM branded charger to power a Blackberry. Hell, I don't need a Sony branded charger for a PSP. Why do we need a Garmin branded auto-adapter for a Colorado? (I made my own power/data cable for my GPS V. Thank you pfranc!)
  20. After looking at the Delorme site, it does not appear that there are any maps for coverage outside the US. Is this correct, or am I missing something? If this is the case, the PN-20 doesn't make any sense for non-US users. (Specifically I am interested in Street and Topo maps for Canada.)
