-Freya (FREquencY Analysis) is a visualising tool for live-viewing the 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. +Freya (FREquencY Analysis) is a visualising tool for live-viewing a signal received by a station.

-Díky ssh tunnelingu můžeme data přenést z libovolné vzdálené stanice přes zprostředkující server. K tomu je potřeba využít takzvaný port-forwarding, který umožňuje otevřít port ze stanice na server a z klientského počítače na server. Postup otevření tunelu je následující.  +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 a station to a server and from a client’s computer to a server. To open a tunnel, follow the example below: 
- +   
-Přihlásíme se na stanici ze které chceme signál přenášet. A otevřeme port na server, který bude fungovat jako prostředník přenosu.+Sign in to a chosen station. Open a port to server that would serve as a mediator of the data transfer.

-Pak otevřeme tunel z pracovního počítače na zprostředující server. +Next, open a tunnel from your computer to the mediation server.

-Freyu pak spustíme z jiného terminálu s odkazem na lokální počítač. Tj. jako kdyby jsme Freyu spouštěli přímo na stanici. +Use another terminal to run Freya with a reference to the local computer - as if you run the Freya directly on the station.
