I'm guessing that some sort of a laptop or tablet is being used to transmit SSTV. A strong carrier and a weak modulation suggests that all they probably have to do would be to "turn up the volume" of the laptop audio output. I'm just grateful that they are able to do these things from up there, for the benefit of the ham community ! I had several kids and parents fired up about capturing these images, since all they need is a laptop + cheap SDR dongle + some free software. May be better luck next time... 73! Umesh k6vug

I have had some good passes of the ISS over Georgia , but there seems to be some kind of audio problem with the Slowscan. The carrier is great, but audio is very low . Is there a way someone can check and advise ?
Thanks DE KG4WBB
