So true...

Ah, but if the receiving point is not an amateur station, you are then
also covered by 97.111 which precludes you from communicating directly
with non-amateur stations except as authorized by the FCC.

The person you are sending the information to is either the "general
public" (one-way transmission specifically for reception by
non-amateurs) or an unauthorized station (two-way communication with a
station not authorized by the FCC).

As you pointed out, "intent" is key.  For instance, if I am transmitting
APRS information that a non-amateur receives and decodes, that is not
the intent of the transmission _unless_ that is who I _intended_ to
receive the transmission.  If I am transmitting on 144.39 in the U.S.,
such intent would be very difficult to prove, indeed.  On the other
hand, if I put a receiver in a hot air balloon (the start of this
thread) for someone to receive those packets along with all the other
hams' packets, intent would still be very hard to prove.  If we move to
another frequency which is unused in the area specifically so the person
in the balloon can receive only my transmissions or if I simply put some
sort of identification in the transmitted information specifying that it
was for the person in the balloon, then intent would be very easy to

As you hint at in your post, very murky waters when dealing with
"intent" in the legal system.  For those who might consider testing
those waters, is it worth your license to find out whether you are right
or wrong?
