About APRS and the CWOP
Click on a station for more information.
Automatic Packet Reporting System (APRS) is a 2-way tactical communications mode using ham radio. It can be used for text messaging, weather station reporting, or to track mobile stations’ positions using GPS. 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.Radios such as the Kenwood TM-D710A can be used to send text messages to home and mobile stations using APRS. APRS is better than traditional packet becuase it is a hybrid VHF radio and worldwide internet connected system.
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.

NOTE: The U.P. is in need of APRS digipeaters! Consider converting your old 145.01/145.09 BBS or packet node to an APRS node on 144.39 MHz using the WIDEn-N format. No matter where you live, It would be additionally helpful (although not absolutely necessary to help us out) if you interfaced your over the air node with your broadband internet connection using UI-View, a free download. This would GREATLY help fill in the multiple holes in the coverage in the U.P. and enable better posting of information to the internet.
We especially need stations near:
