QUISK, which rhymes with "brisk", is a Software Defined Radio (SDR).
QUISK is a Software Defined Radio (SDR). You supply a complex (I/Q) mixer to convert radio spectrum to an intermediate frequency (IF) and send that IF to the left and right inputs of the sound card in your computer. The QUISK software will read the sound card data, tune it, filter it, demodulate it, and send the audio to the same sound card for output to external headphones or speakers.
Quisk can also control and demodulate data from the SDR-IQ from RfSpace.
Quisk works with the quisk_lppan_k3 package by Leigh, WA5ZNU, to control the N8LP LP-PAN panadapter and the Elecraft K3.
