Careful, some clarification might be in order for APRS. APRS can be
set up with different types of devices. There's the 1-way 'dumb'
trackers that just send position reports (a la SPOT), then there's a
full up HAM in the cockpit. So it's the equipment capability, not a
frequency thing. Look at it this way, you have a choice of what
equipment to use: a 1-way tracker that just broadcasts and doesn't
receive, a 2-way device, and also a 2-way device that is setup in a 1-
way mode.

We should encourage position reporting by whatever means.
