From the developer:
RCKskimmer is an application capable of searching for digital signals in a FFT-spectrum of a standard receiver with a NF-connection to the soundcard of the PC by using the MMVARI module. All bands and frequencies can be scanned in a row and all callsigns with CQ, QRZ, DE or TEST will be detected and listed with exactly mark-frequency by using the OmniRig Transceiver Control.
