-====== Freya - 3D meteor visualising software ====== +Freya (FREquencY Analysis) is a visualising tool for live-viewing a signal received by a station. It is suitable especially for presenting the data to visitors thanks to its simple intuitive representation of waterfall diagram that does not contain any details. Thus it differs from [[en:pysdr|PySDR]] software, which, on the contrary, serves as a tuning tool when servicing stations.

-Thanks to ssh tunnelling, we can transfer data from any remote station through a mediation server. You have to use a so-called port-forwarding, an technique enabling opening a port from station to server and from client’s computer to server. To open a tunnel, follow the example below:+Thanks to ssh tunnelling, we can transfer data from any remote station through a mediation server.
