What rules govern the PropNET service?
PropNET is considered an international service. However, radio licensing regulations differ from country to country, so it is important for PropNET participants to know and abide by the rules of their own licensing authority. In practice, PropNET operates in a very similar way to APRS (http://www.aprs.net). Like APRS, PropNET stations form a network for sharing information, just like people in an SSB roundtable. This means that the rules governing PropNET are essentially the same as those governing APRS in your country.
