Receiving and Decoding APRS Data

This section describes one way of setting up a Windows PC to receive and decode APRS data. Be aware that there are

quite a few applications that will do the job however the author is only familiar with the details presented herein. Also note

an in depth step by step guide is beyond the scope of this manual so only a brief overview is presented. For an in depth

step-by-step guide, please visit 

http://patmedia.net/ralphmilnes/soundcardpacket/index.html

.

What you will need

1.  PC running Windows 98, NT, 2000, ME or XP with a built in sound card
2.  2m or 70cm receiver tuned to the same frequency as your ZTrak / Zares transceiver
3.  An audio cable to connect the Zares to your PC

Download and install AGWPE

The key to sound card packet is a free program called AGWPE, a program written by George Rossopoulos, SV2AGW. It

can encode and decode packet tones using your computer's sound card. It is particularly valuable since it can act as a

"host" program for several good packet programs that do not have sound card packet capabilities of their own like

Tumonz, Etc.

  Download from 

http://www.elcom.gr/sv2agw/agwpe.htm

  Once installed, you need to set up a Sound Card Radio Port

Download and install AGWTracker

AGWTracker is a program that will display APRS packet data from the Sound Card Radio Port you set up. Among other

things, it allows you to receive and send APRS data to or from the radio port or Internet. You can monitor the decoded

APRS packets, view a list of stations received, send and receive APRS messages and view station location (globally) with

the stunning on-line VirtualEarth or GoogleMaps. You can even load in your own maps!
