You are, of course, correct. I had thought somewhere in my befuddled brain
that you could just send a filter command without a login and get a feed. It
appears not from my cursory testing.

Surely. We definitely want to get the correct data out there for folks.
Apologies for the misinformation.
Again, the other trick is that you won't get a feed on any filter that needs
your own position until you send a posit. So, if you have such a filter and
have unchecked "Allow Transmitting?" in Xastir, you probably won't get any
data. Use an r/ filter or another alternative that doesn't need to know where
you are.
Thanks for the clarification Lynn.
