Ignacy, I routinely run 1500 watts CW, using the same antennas that I use for Skimming with my RP.  Of course, that means that there is no antenna on the RP when I'm transmitting.  The device that I use for this switching, an RX Audite, has extensive protections for both the transceiver and the SDR, but no bandpass filtering.  Not surprisingly, when I transmit on a given band, Skimmer Server shows a lot of phantom decoders on that band, but I have identified and blocked (on the Bad Spots list in the Aggregator) all of the permutations of my call that this produces.

As for the setup, someone who knows Linux should have no difficulty.  There are several useful guides to setup and operation on the RBN web site.

I use SDR-IQ for skimming. The antenna is a Wellbrook loop some 500 ft away from the shack and oriented to null the TX signals. It works pretty well, as I am able to spot signals some 5 KHz from the transmit frequency even at a KW level. But the setup is single-band.

If I change to Red Pitaya, how much time does it take to set up everything for an expert, and for a casual user who knows Linux? Since Red Pitaya has no bandpass filtering, is it easily blocked by TX signals on any band?
