WESTMINSTER, MD.�Carrier Sleuth, from small software developer Black Cat Systems, is designed to aid serious hams digging out overpowered medium-wave signals.
It operates as a specialized FFT (up to 32 million points) to generate RF waterfall of signals provided by software-defined radios such as SpectraVue, SdrDx, Perseus, Studio1/SDRUno, ELAD and Sdr-Radio.
Black Cat Systems explains: �While you can often only hear one, or perhaps two, stations on a frequency at a time, chances are there are actually many other stations lurking on that frequency � The problem is that they are too weak to notice using normal listening techniques. There�s no audio, and even their carriers are often quite weak. But by performing very high-resolution FFTs on recordings made by SDRs you can extract these carriers up out of the noise and see them.�
Carrier Sleuth is available for Windows and Mac and is currently free. Black Cat Systems also has a number of fun RF and audio software toys to check.��
