[Skimmertalk] Transition from SDR-IQ to Red Pitaya

[Pete Smith N4ZR]

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.
