SSTV extension for KiwiSDR
« on: May 24, 2025, 2304 UTC »
The SSTV extension for KiwiSDR does not allow frequencies outside of a short list of frequencies.
D/E/F/G/It/Sp : Dutch/English/French/German/Italian/Spanish
+/- : about 0.02 offset, ++/-- 0.03/0.04 offset
Balanced wire antennas, wire lines and ATU

Not true, it works but you don’t pick a frequency. Just tune into the one you want and leave the extension open. It is a terrible decoder anyway though.

Songs are identified with Shazam if needed. I usually use KiwiSDR receivers. Reception from my QTH is using a Hermes Lite 2 with a 40 meter band Inverted V at 40 feet.

FWIW: My Black Cat SSTV decoder https://www.blackcatsystems.com/software/sstv.html can be used along with my KiwiKonnect program https://www.blackcatsystems.com/software/kiwisdr_software.html to decode SSTV on KiwiSDRs, just pipe the audio through a virtual audio device/cable.

Well, nothing happened as I was hearing SSTV from Pop Shop Radio relayed in Europe with a good signal on a KiwiSDR. Not the first time I tried this way.

SSTV images are scarce on free stations here in Europe. So I no longer want to try independant decoders. The one I used years ago was a plague to save the decoded images.

It likely missed the images just because it is a poor decoder, if it misses the start it won’t work and some modes I can never get to work. I always use MMSSTV, getting the audio routed to it can be kind of difficult but once you do it works great.
