I want to thank everyone that made comments, suggestions, and information to my original post. I really appreciate it. What I found out, is that there are a lot GPS on the market and most of them will do what I want. I just have to make up my mind on which one. Thanks again to everyone.

All, Thank you for the responses to my email this morning. Thanks to Nick (KB1RVT) for doing a little bit of legwork and discovering that the Venture HC has the Maidenhead display! Yay!!!

The Garmin GPSMAP 76S is a discontinued GPS receiver: https://buy.garmin.com/shop/shop.do?pID=183 I can make its main display show either my latitude/longitude or a grid locator. No need to convert latitude/longitude to grids or vice versa. Many Garmin GPS units, and some from other manufacturers, have this functionality. In a quick scan of the PDF manual for your Venture HC GPS, the word "Maidenhead" - the fornal name of the grid-locator system - did not appear. It doesn't look like you can make your GPS display the grid locators directly. It does have a screen where it shows the latitude/longitude and accuracy figure, so it could be used if you took the pictures to document your location on a grid boundary or 4-grid intersection. 73!

I have not seen the FTM-350 with its optional GPS, to see if it is any different than the VX-8 radios. The displays for the VX-8R I previously had and my current VX-8GR shows the latitude and longitude, speed, altitude, time, a compass heading, and how many GPS satellites are being used to determine your location. It would have been nice to have the grid show up on the display (possibly by a turn of the VFO knob, similar to how you bring the time up on the GPS display of the VX-8GR), but I'm Ok with what I get on the VX-8GR display. For its intended purpose, the VX-8GR is perfect as is. I can use my Garmin GPS to figure out where the grid boundaries are. 73!

[amsat-bb] Re: GPS for dx-expedition
Zack, I used to have a old Garmin GPSIII that would display maidenhead grids. Used it when I would rover in the VHF contests. Very simple to use and very very cheap now on the used market. It's OLD technology but I don't think anyone will fault you for using it even if it isn't as accurate. It'll get you close enough and to me as long as it shows the grid that you are passing out on the screen then you've made a "good faith" effort to do things right. BTW: Nice to work you on SO-50 the other night. QSL will be in the mail. 73 Matt W5LL On 9/2/2010 8:27 AM, Zachary Beougher wrote: > What is this 'GPSMAP76S'???

Several have reported to me that some of my grid-boundary expedition QSL cards were questioned by VUCC card checkers, even with the GPS latitude/longitude readout printed on the card. I have never been contacted by ARRL to provide any documentation regarding my grid expeditions, but there's always a first time for that in the future. I prefer to be safe and have all of that with me, than not have it for the one time I may be called upon to provide the documentation. As for Don Miller, yes - I am familiar with his escapades. When the VUCC rules were updated in late 2008 to coincide with the new Fred Fish award for 6m, I made sure to understand them and comply with them for anything I did after that point. I don't want other satellite operators to lose credit for grids they worked me in and have my cards for. 73! Patrick WD9EWK/VA7EWK http://www.wd9ewk.net/ ___ Sent via amsat...@amsat.org.

[amsat-bb] Re: GPS for dx-expedition
I have one; what would you like to know about it (never having been on a DXpedition myself)? I find it is a very good all-in-one GPS. I use it in the car, on hikes, etc. It's small enough to fit in my pocket, and big enough to see what's on the screen when driving. I found that one of those big black spring clips works well on the dash air vent, with the GPS back's clip carefully threaded through the spring handle. Battery life is pretty good (I use 2450mah NiMH batteries in it). I bought mine a number of years ago, swallowed hard and bought the maps too; the base map that comes with it is NOT sufficient for most navigation purposes. Recently I found an on-line site that has a number of topo maps that work with it too, so it appears to be actively supported by the community. Also a lot of "points of interest" that you can download. There's a GeoCaching "app" built in, for those into that sort of thing. The interface to the outside world is USB only (no serial or bluetooth), so that's a big downside if you want to do APRS with it. I decided that the advantages of the unit far outweighed that negative, meaning I'd have to buy another GPS something for APRS. (Ended up buying a little GPS module from Sparkfun for APRS work with my D7). The only problem I have with it is that the glue that holds the rubber band that rings the unit has failed, and the rubber is sort of floating around the outside. It seems to have stretched, though I have no idea why. Maybe the rubber and the glue were incompatible. Oh, also the internal barometric altimeter is great when it's calibrated, but the automatic calibration often gets confused and puts me at some really wacko elevation. I wish the priority went to the GPS Altimeter, with the analog one only coming into play on request.

Jeez, folks ...lets get a grip I deleted the original guy's question, but my sense was that he was asking for advice on buying a GPS that would tell him where he was when he hit a sat. I don't recall that he asked how to build a watch when he just needed the time !! So, I'll pose my question along the same premise: Is there a 'ebay'/used/or ?? other unit that will give us a grid position that one can put on a qsl card? Personally, I don't need to know the degrees between my mailbox and the end of my driveway. Most of us in the VUCC hunt just need to give a GOOD FAITH grid square for the other station.

[amsat-bb] Re: GPS for dx-expedition
Jim, I've had the Vista HCx for several years now and am quite happy with it. It compact ( a plus when packing a lot of other gear) but quite functional. I use mine for Geocaching & general navigation. I have Garmin city navigator & Topo 2008 on it along with a free version of Arizona topo. Plenty of room on the SD card for all the maps you can load. This model also has the magnetic compass and barometric altimeter as well. One nice thing I noticed when starting to work bird is that it has a datum for maidenhead. You can read your grid square right off the screen. My only beef with it is the screen is hard to see during the day without the backlight on, which needless to say cuts into battery life. I believe it's still in production and is a bargain if you get the bundle from Cabelas. (GPS, Case, SD card, & Topo). Hope this helps. 73 Clear Skies Rick Tejera Editor SACnews, Public Outreach Coordinator Saguaro Astronomy Club Phoenix, Arizona www.saguaroastro.org saguaroas...@cox.net K7TEJ -Original Message- From: amsat-bb-boun...@amsat.org [mailto:amsat-bb-boun...@amsat.org] On Behalf Of KE4KOL Sent: Wednesday, September 01, 2010 18:41 To: amsat-bb@amsat.org Subject: [amsat-bb] GPS for dx-expedition I am looking into purchasing a Garmin "eTrex Vista HCx" GPS to use for dxexpeditioning in working different grids.

Hi Jim! > I am looking into purchasing a Garmin "eTrex Vista HCx" GPS to use for > dxexpeditioning in working different grids. > > Has anyone got any reviews on this gps? > > Does anyone suggest a better one to use for dx-expeditioning? This looks like a viable GPS for grid expeditions. It has a screen with both the latitude/longitude and the accuracy figures, so it could be used to satisfy VUCC documentation requirements. Maybe a little on the expensive side, but it would work. I use a Garmin GPSMAP 76S to find the grid boundaries. I can quickly go between latitude/longitude and Maidenhead locator, and can show that accuracy figure on the same screen as the latitude/longitude or Maidenhead grid. It is capable of having updated maps loaded on it, to augment the base map it comes with - something I have not done with mine. On the QSL cards you've received from me, you see photos of the latitude/longitude display of this GPS. It has been discontinued, but the GPS 72H is a successor to my unit. The GPS 72H doesn't have all the bells and whistles that my unit has, but the price is not as steep as the unit you are looking at. It does have the same sort of display as my unit has, with the latitude/longitude and accuracy figure on one screen. If I needed to replace my current GPS for my grid expeditions, I would probably go with this unit to avoid separating myself from more of my money to get another GPS. With the mapping capabilities in GPS- equipped smartphones, I do not see a huge need to have a GPS with detailed mapping. There is some advantage in making use of smartphone-based GPS applications for reasons like those Drew mentioned, but I still like having the GPS that will meet all requirements for VUCC documentation. None of the GPS-related apps on my two phones (Nokia N900, iPhone 4) nor my VX-8GR show that accuracy figure. The VX-8GR will show a count of the number of GPS satellites it is using to determine my location, but I have not seen any documentation that could translate the satellite count to an accuracy figure in feet or meters. I've never been asked by ARRL to provide documentation for my grid-boundary activities, but I want to be able to meet those requirements if I am ever asked to provide the photos and other proof I have. 73!

I use a free app for my Iphone to determine what grid I'm in, whereas I used to use a Garmin 2XL? purchased on one of my first grid trips to the midwest 10 years ago. The Garmin Nuvi the wife had (before it's midnight liberation from my rental car in Dayton) also would give you a lat and long if you knew where to look in the menu. The minor inconvenience of having to convert to the maidenhead coordinates was small compared to having a GPS that was easy to use for highway navigation and finding Shoney's breakfast buffets. 73, Drew KO4MA ___ Sent via amsat...@amsat.org.

My only hesitation is that it was released in 2007, I believe. I would do a Google search for reviews on the unit before I'd purchase - to see if you're missing out on anything that more current models offer. AND make sure Garmin Maps are still completely compatible with it. Clint, K6LCS ___ Sent via amsat...@amsat.org. Opinions expressed are those of the author. Not an AMSAT-NA member?
