Ham Radio Reporting Networks
Ham Radio Reporting Networks have been used by contesters and researchers alike to assess propagation conditions. Most of our current HamSCI projects rely heavily on one or more of these networks.
- DX Display (Aggregates data from other spotting networks)
- PSK Reporter
- Reverse Beacon Network (RBN)
- Weak Signal Propagation Reporter Network (WSPR)
Reverse Beacon Network (RBN) How-To
The Reverse Beacon Network (RBN) is a network of Software Defined Radio (SDR) receivers which automatically decodes and reports spots of CW and digital signals. These guides describe how to setup multiband RBN skimmers and make recordings to a file.
