Welcome to the first episode of Season 2 of the Fat Bird, Ugly Dog Podcast.  In this episode I talk to Kevin Harcourt of Marshall Radio Telemetry.  Kevin tells us a little about the company, its philosophy, and how he came to be part of the Marshall Radio team. We then distinguish between Radio Detection Finding (RDF)  technology and Global Positioning System (GPS) technology, including components of each system and the way in which each system combines component-specific functions that allow users to keep tabs on a hawk's location. On the GPS side of things, we talk about the LED displays, how to interpret the various LED colors on the transmitter and the pocket link, and how to get additional information from the LED display on the pocket link when trouble shooting or tracking a lost hawk.  Kevin also describes raw data and derived data.  We finish out Part 1 of this 2-part episode discussing the trade off between battery longevity and data acquisition associated with each of the four user-selectable modes (HD, ECO, EXT, and SLEEP).
