  • Argent Data Systems - OpenTracker 1+

    BRAND NEW! APRS tracker module. The new plus version has all of the features of the original 1x with the addition of software decoding for two-way waypoint operation, better known as the "Anti-Tracker" method. This function allows for decoded position packets to be sent to your mapping GPS as a waypoint to show where other APRS stations are, around you. Open source and freely upgradable through their Windows configuration program. Has larger 7805 voltage regulator to power Deluo style GPS receivers directly. (We recommend Deluo, but just about any GPS that requires 5VDC for power will work) This unit is available Pre-Built and tested by us. Includes case.
