Merging KrakenSDR stations

Hello, can you please tell me how to connect 2-3 KrakenSDR devices to one network only when using KrakenSDR RDF Pro?

And the next question is, is it possible to work such a network without the Internet?

Just register your three Krakens to the KrakenSDR RDF Pro mapper at, and enable KrakenSDR Pro Remote in the web GUI for each Kraken (making sure to input the API key for each one that you got from the mapping site.

You’ll need an internet connection to use the web mapper, no way around that, the data has to get to the server somehow.
