Black Cat SSTV

Why yet another SSTV app? I've been an SWL and DXer for about 40 years now, and writing SSTV apps for about two decades now in one form or another. Part of my activity involves decoding extremely weak SSTV transmissions. It's easy to write an SSTV decoder that works with a strong signal, but I decided to write a brand new SSTV app from the ground up, with an emphasis on performance under weak signal conditions.

The result is Black Cat SSTV. If you want an SSTV app that will show you the DX you've been missing, Black Cat SSTV is for you.

It has an extremely sensitive VIS detector, with an adjustable threshold, which can be adjusted depending on your tolerance for false triggers. Images are automatically adjusted for skew and offset after reception using all of the transmitted information, for nearly perfect lock even under extremely weak signals. Often you can barely hear the transmission, yet you get a nice copy. Images can be automatically saved in the directory of your choice, and there's a built in gallery for viewing received images.

Transmission of images is also supported of course, and there's a basic editor for preparing images for transmission. Serial ports (physical or virtual via USB/serial adapters) can be used to trigger the PTT signal if required.

Available for both Windows and macOS.

Black Cat SSTV integrates with the SDRPlay SDRUno software package via the free Black Cat Systems plugin. Instructions for configuring both are available on this page.
