30 minutes of APRS with Bob Bruninga, WB4APR

This is the first 30 minutes of Bob Bruninga, WB4APR giving a talk at my amateur radio club HOSARC. It was a very informative talk and I hope to get the rest of this talk in the near future. Bob's presentation was incredibly informative. If you ever get a chance to see him give a talk, run, do not walk. He is a tremendous resource to the amateur radio community.
