First screen on D-7 provides
CALLSIGN, MODE, LOCATION
This can be a rough location (City name) or, as in this case the best Interstate Rest Area.

Second Screen provide
DISTANCE and DIRECTION
Very helpful if you want to set up a beam.
This does require that the D-7 know where it is from a connected GPS

Third screen provides
ACTUAL LAT/LONG FOR MORE PRECISE LOCATION
This can be used with maps or an external GPS that is not connected to the D-7

Fourth screen provides
INFORMATION ON ASSET CAPABILITIES
Here we see 49 watts power at 20ft with 6db omni antenna.


All of this information is sent in the following single line. Note the extra spaces to pad the information to display on the D-7 / D-700. This does not inhibit the display on any full function system and helps the mobile operator gather data in a usable format.

So in a single line of data we know that there is a TelPac 1200 baud node CALLSIGN KC4ZGQ-5 that is located 3.6 miles to my west. This node is running ~50 watts with 6db omni gain so it should be easy to work. The notation I-475 NB is my way of specifying a good rest area for accessing this node. This type of information is available to any station that simply listens to any frequency that allows APRS packets to define assets.
