    We've noticed a huge increase in rants and negative posts that revolve around agencies going to encryption due to the broadcasting of scanner audio on the internet.

    If you violate these guidelines your post will be deleted without notice and an infraction will be issued. We are not against discussion of this issue. You just need to do it in the right place. For example:

Not APRS, but Automatic Identification System (AIS). It broadcast on VHF-FM marine radios channels 87 and 88. AIS is tied into the vessel’s GPS to show the current position. Way more on AIS then we can cover in this forum and more information can be found online by googling this term.
