Geocaching Presentation to Hams

Recommended Posts

Guest RedwoodRed

I need to give a presentation on Geocaching to our local ham club the first Thursday in January. I recently published an article in our local paper about Geocaching, and I was thinking of making copies of that to pass out, but other than that and taking in a few GPSR's, software ideas, some accessories, explaining the rules and maybe taking in a sample cache (ready to place)... I can't really think of how to fill up 30 minutes for this.

 

Anyone have any ideas to help? Many of the club members already have GPSR's, and many of them have expressed interest in APRS to me in relation to this.

 

Thanks in Advance...

How about explaining something about how the GPS systems works?

 

As in, the frequencies it uses, the antennas on the sats and the different antennas available to use with GPS units. Then you miht mention the 'optimum' conditions for best location. Errors that creep in due to multipath effets and the way that fixed statins, in very accuratly known locations, can transmit additional signals to improve accuracy.

 

You will probably find that some of the Hams there are into communication via oriting satellites, so will be interested in how many are up there, and how they ca get programs to plot their locations (www.satscape.co.uk might be worth giving out to them).

 

Some of them may well use the 23cm (1.2/1.3GHz) bands, which are near the GPS satellite frequencies, and will be interested in the effects of multipath and inospheric degredation. They might also be interested in the types of antennas used.

 

The APRS nes might be interested in combining the use of their GPS units, with the various rigs that enable them to transmit their lat/long, with geocaching.

 

Hope some of these ideas help?

PS - Sorry about the typos!

 

I have problems with this replacement keyboard. It keeps missing letters that I type.

 

I think the meaning is not lost, even though some of the letters are missing.

Sounds like fun! I'll have to get a presentation setup for our club, too!

 

Get the word out for members to bring their GPSs to the meeting. Hide some inexpenive markers, like poker chips, to serve as geocaches for the evening. After you do your talk, handout sheets with the coordinates, and turn 'em loose. You could have them work in teams to make the contest a bit simpler. The team that comes back with the most chips wins. And no rough stuff allowed! ;-)

 

Or, you could give your audience until the next club meeting to turn in their chips. You could demonstrate the geocaching process by taking the whole group out to find just one poker chip cache, or a real geocache, if there's one nearby. That way they'll have had a private lesson from the expert - you.

 

Or, you could skip the demo cache idea, and just tell them to REALLY go geocaching. If they post log reports for the caches they find, you could read them at the next club meeting.

I like the idea of setting up the mini cache course. Most hams could use the exercise!

 

But seriously I think this is the best route. Perhaps you could could compare the sport to foxhunting prior to the search.

Thanks Folks!

I have taken all of your responses into consideration and here is what I have planned:

 

A brief discussion of how GPS function, the satellites they use and a bit of their technology, the technical make-up of the GPSR's and how to modify them (Thanks, Morseman!), and I am taking in a ready-to-place geocache so they can see what one looks like.

 

I'm also just about done with a paper that I am handing out with links to other geocaching websites, product websites and places to find other information related. On the sheet will be the coordinates to a special geocache only for the club members or those who attend. They will have until next meeting to find it, and all of the items will be gimmes (they don't have to trade, just take), to get them started. I won't post the coords on geocaching.com, so that they have a better chance at it.

 

Thanks again!

Good luck with the talk, please let us all know, on here, how it goes.

 

BTW, one of the links (the one to the W6HY site) comes up that I'm not authorised to view it.

I want to thank all of you who gave me ideas on what to use/present at my GPS/Geocaching demonstration last Thursday.

 

I choked up a bit, but I knew that I might and prepared a paper how the NAVSTAR system came into being, how it is utilized and a bit of the technology behind it, including hyperlinks to my sources. So when I began to stutter a bit, they at least had some text to look over and take home with them.

 

I had three GPSR's to show (my own and the two others belong to friends), my S.O.'s "backpack portable" (his backpack complete with HT, water bottle, compass and an assortment of items to trade), and a complete, ready to hide Geocache filled with inexpensive items sure to appeal to any Ham (solder, batteries, PL-259 connectors, etc.) to hide after the demonstration.

 

I explained that the geocache was for those who attended the meeting and their families only, that it would not be posted to geocaching.com for 30 days, and that I did not expect them to trade anything, but instead just take one item apiece. I did explain the one-in/one-out trade policy of a normal geocache, but that it did not apply to this one.

 

I have posted the paper to our GeoGadgets website, if you care to look, but I am sure that the information I have listed will be old-hat to all of you.

 

Thanks again!

Thank you for letting me know. We had been having trouble with the web host provider. It had been discussed whether or not to change hosts two months ago. This proved the catalyst getting everyone to move the website. It should be up and running now.

The website is fine, except it wouldn't let me sign the logbook. But, I'll go back and see if I can find an address to email someone to look at the links.

 

Cheers.

we did one of these at our local club and at the monthly arpsc/ares meeting (yes, they are one and the same here in miami to avoid endless bickering).

 

we explained what geocaching was all about.

we talked about where things are sometimes hidden and what treasures or trash you may find, and the most important thing in my opinion was tying into something useful for those that didnt see the "fun" in it.

 

geocaching gets you familiar with the quirks in your gear and sharpens your orienteering skills. i tied this in with some practical examples of when geocaching skills could prove handy...

 

finding a downed aircraft purely on coordinates. navigating a disaster area purely on coordinates. exchanging supplies while on the move by creating temporary private geocaches with emergency supplies or equipment for example.

 

these things are very real applications for skills learned in geocaching. after hurricane andrew in south florida, there where no street signs in much of south dade. many folks relied on whatever landmarks where left and others used gps and coordinates to get around.

 

if you cant sell'em on the fun, sell'em on the usefulness of the skills learned.
