Geocache Description:

This cache is not at the posted coordinates


Some Info about the cache....


(With this cache you find it with maps, not coordinates.)

Why a roving cache?

In an attempt to do something different with Geocaching, some people came up with an idea of a moving cache. Having a full-time APRS tracker in my Jeep, I thought it was a good idea to implement my Jeep as the cache.

What is APRS?

APRS, which stands for Automatic Position Reporting System, is the fusion of GPS technology and Amateur packet radio. APRS is not new, amateur radio operators have been doing it for years. APRS also allows for more than GPS tracking, such as an APRS weather station or a method of sending messages via the APRS radio network.

How do I find the cache?

This cache will take a little more technology than your GPS (Unless my car is stationary for awhile)

Here are some ways you can hunt for the cache:

  • Mobile Internet

If you have a data cable for your phone, you can track it on the Internet in near real-time (taking internet lag into account)

Go to http://aprs.fi/?call=kd7lrj-5

  • Radio with built-in TNC such as Kenwood TH-D7A or TM-D700 connected to the GPS via the GPS port.

This allows direct display of APRS stations on your GPS if it supports NMEA data-in. Stations will be listed as waypoints in your GPS.

Using the WinAPRS software in conjunction with your TNC which decodes analog audio data packets from a scanner/radio. The scanner/radio must be able to tune into the VHF frequency of 144.390 Mhz

Research.

With a little amateur radio knowledge you can figure out the QTH of AD0OR and it is often found near the garage there.

Probably the cheapest way to get into it, you can use your sound card and special software to emulate the TNC

What's a TNC?

A Terminal Node Controller is a fancy way of saying "Radio Modem"

Most TNCs run at 1200 baud, which is all you need to monitor the local APRS data network.

A new type of cache, inquire within...
This is a cache of a different sort of challenge, it tends to move a lot!

Q. How does it move?
A. It's in my Jeep, on the back of a dark Jeep Wrangler.


Q. How do I find it?
A.well, I would just look at the maps.... or you'll either need a mobile internet connection to your laptop or you'll need an APRS tracking system,
Tracking on the Internet: With your trusty laptop or portable computer, go to http://aprs.fi/?call=kd7lrj-5 Just make sure the data is up to date because the net tends to lag a little behind at times.

The cache is an Ammo can on the back of the Jeep.


It's better to track with an APRS monitoring station, which consists of a scanner, TNC, computer, and some free software like WinAPRS which can be downloaded here.
