Our amateur radio club provides health and welfare communications for the participants of the Wausau Marathon. This year I was the ‘bike mobile’ station providing a sweep so net control knew where the tail end of the race was. This video illustrates how I used APRS with a handheld radio and external antenna to provide solid coverage of my location while on the course.
