Portable Receiving System Overview

Sigma Eight Inc’s portable receiving system is an innovative and low cost assortment of equipment used to track radio transmitters for wildlife research. In order to utilize this system, it centers around the Pisces Decoder app for Android™ which is available for purchase on the Google Play store. The system works by having the user feed audio from the handheld receiver to the Android™ device. Pisces Decoder will then decode any pulses detected by analyzing the time interval between them. A code will be determined and displayed, along with the signal strength and coordinates of the Android™ device. The system is fairly robust, and can usually decode any radio transmitters that are audible from the receiver.
