Thank you to Walter Panella (IU2MEH) for submitting information about his Shiva DX Cluster software which is designed to be used with SDR-Console V3. A DX Cluster is a type of distributed network of software that is used to to advertise that long-distance amateur radio DX stations are transmitting. Walter writes:
Shiva DX Cluster connects to a ham radio dx cluster and repeat the dx spot to shiva clients while adding spots based on list files.
It doesn't send to ham radio dx cluster any spot nor it can receive any spot.
It is intended to use with SDR Console for SWL/BCL ( see screenshots folder ) so they are able to see broadcasting stations, for example, based on scheduling day and time.
Ham radio dx cluster spots are repeated to shiva clients immediately, broadcasting stations and other lists are sent to shiva clients every 10 minutes (default,configurable).
The software is available on Walter's GitHub.
