About APRS and the CWOP


Map loads momentarily. Please wait. Move cursor over map for pan left/right or zoom in/out. Click on a station for more information.

Automatic Packet Reporting System (APRS) can be used to track mobile stations' positions using GPS. In addition, amateur Radio operators nationwide use APRS for reporting and tracking severe weather conditions. Any station with a home weather station can connect it to his/her APRS station and automatically transmit weather conditions.

All you need is a TNC, a VHF transceiver, and inexpensive weather measuring equipment to get your station up and running! Of course, if you just want to receive the APRS reprots on 144.39 MHz FM from other stations you can do that too... REAL TIME! CWOP station reports are relayed to the National Weather Service over the air via digipeaters and the receive nodes connected to the internet.

Xastir (Software) Help


Xastir is the best APRS program for Linux and Mac users. The program is a free download and also has many useful features. Xastir has integrated Tiger maps from the US Government, radar overlays, and much more. Why choose Xastir? Linux is a rock solid operating system that doesn't have the rebooting, crashing, and virus issues like Windows. If you have an extra computer laying around, think about converting it to Linux using Debian or Ubuntu and setting up your own APRS station.
