The system includes a digipeater placed high on a mountaintop overlooking the Spokane area, and another fill-in digipeater with a bi-directional I-gate that makes for a complete APRS repeating and reporting system using no more than two hops.
Digipeated packets containing beacons and messages are reported to the Internet based global APRS-IS tier 2 network so anyone in the world can see the information. Also, any packets from the global APRS-IS network, destined for stations nearby, will be transmitted by the WA7DRE APRS I-gate transceiver, and repeated by the WA7DRE-11 mountaintop digipeater. If the destination station cannot receive the packets directly, other nearby digipeaters may echo the packets to help ensure the packets are received.
