APRS Variable Replacement Script
This script is available for anybody who wants to design their own simple web page and embed the latest APRS packet data for a specific station.

You just design your own HTML page, have it hosted anywhere you wish, paste the desired variables wherever you want them to appear on the page, and then pass your page's URL to this script, along with the callsign of the station.

For instance, I've created a page in my personal space on another server:

http://www.warn.org/brad/aprs.html

You can see the variables that appear in the page, such as "$call" and "$lat". Those variables will be replaced with the actual data from the most recent packet of the specified station...

Here is the same page when passed through this variable replacement script:

http://aprsearch.net/replace/index.cgi?call=n8qq&url=www.warn.org/brad/aprs.html

     or you can call it like:

http://aprsearch.net/call/n8qq/www.warn.org/brad/aprs.html

Just put your callsign and your web page's URL in place of mine (shown in red), and that's all there is to it. In the first example URL above, you can optionally specify a protocol on the front of your URL if it's different than "http://".

Check here to view a list of all possible variables. You can use this list to copy and paste them into your HTML page.
