The grabber is made from a simple SDR kit, the Soft66Lite, a Behringer UCA202 USB sound card. The SDR receiver is SDR# and the FFT processing and display software is PA2OHH's excellent analysis program LOPORA. The SDR radio has a crystal frequency of 20.250Mhz with a piece of copper soldered to it, inside a homebrew crystal oven.
