[aprssig] APRS legality

Ben,

Apparently we disagree.  I contend that APRS is a network.  The
network is composed mostly of stations that are transmitting and
receiving local data to each other.  I just don't see any other
way to see it.

Similarly, transmissions from transmit only telemetry devices
are one-way, and there too, I cannot see it any other way.  Yet
the difference between the first case (2-way with transceivers)
and the latter case with transmitters only, is a really, really
big difference to you , me and the FCC.

I contend it is that distinction that the FCC was trying to
define in their distinction of one-way transmissions.

Bob
