Hence the strong request for people to set a minimum transmit interval of at least 1 minute for mobiles (we recommend 3 or more minutes in the DFW area where 144.39 is saturated).

  Yep... I wish that dupe check would solve the problem. The problem is
not fixed stations.... at least round here. It's folks that are driving in
parking lots or around certain parts of the city (we are not a grid layout
city) that have the trackers set too liberal. Too many packets are being
transmitted. Of course we do educate folks about this but the problem
still exist.

  The best way for it to work (IMHO) would be a CALLSIGN dupe. That way if
you were just pinging along in a parking lot, 2 callsigns in 30 seconds
would digi only once.
