True, but does it need to be on RF? And can a driver of a vehicle absorb it
or make any use of it?  If not, then most off it (out of area) should be
kept on the internet for the shack potatoes.  In the shack, most everyone
has access to anything from 56 Kbps to megabytes.  In the car, its only

We may have lots of stations on the air here, but few are doing anything
that anyone else would be even the slightest bit interested in.  They are
just driving to and from work.  If I took EVERYTHING going on in this area
on the other 95% of ham radio and put it on 144.39 in 1 second beacons per
activity, then it would still all fit on 144.39 at 1200 baud with room to

Agree. But if we want to see what is going on in ham radio in my area,
putting out basically nothing at 10 times faster is still basically nothing.
I have little interest in filling up a bigger list of stations and objects
in my radio of which I have little or no interest.

What I do want to see is anyone doing anything in ham radio that would be of
immediate interest to others.  One such thing is their operating frequency
right now.  Even if it is CB or HF.  If they are in range, that is more
important than their position.  This is ham radio.  Our mission is
