SpotLink

A Winlink service that responds with WSPR spot reports

Why create this service, and what does it do?

In the internet age, amateur radio operators have rich data at their disposal for selecting which radio bands have the best propagation characteristics. Many folks around the world operate WSPR beacons and listening stations that build a picture of real-time conditions. However, when you're in the field without access to the internet operators don't have access to these resources.

If you have access to Winlink, this application makes it possible to query WSPR propagation data. This makes it possible to:

• Find the best frequencies to work
• Find the best directions to direct an antenna with gain
• Receive data on which Winlink gateways may yield higher- quality connections
