APRS Weather – 1999

BOM Data Receiver


This receiver is used by the Wethalert system being used around Australia.
It uses 1200 BPS BELL modem tones. My intent is to add this data stream to
the APRS data stream in some correctly formatted way

Correctly formatting should not be too much problem. The messages come through
with a lifetime on the message.
