Title: Unknown SSTV 6955 USB 0302 UTC 13 NOV 2017
Post by: dragund on November 13, 2017, 2311 UTC
Not sure if this is the correct forum for this:

The board was showing SSTV hits at 6955, so I tuned in and plugged my radio into my Surface Pro with MMSTV running.  I didn't bother recording or listening for music or voice. 

I picked up one very, very bad SSTV picture that is time-stamped 10:02 P.M. NYC time, 01/12/2017, which is 0302 UTC 13 Nov 2017.  The time may be from when the file was saved, which would have made the beginning of the SSTV transmission a few minutes earlier.

I've attached 4 images.  The first is the original.  The second is after having been processed with the SSTV Image Denoiser tool.  The third is the "denoised" picture processed with Photoshop's "Auto Smart Fix" feature.  The fourth is that image with brightness lowered and contrasted maxed out.  This is my system for cleaning up these crappy images that I receive.

I see a woman in the middle of the image and another woman on the right.  There may be a woman on the left, but I can't tell.  I hope I'm not violating any TOS by posting something that may be risque.

Did anybody else pick up a better version of this image at the time?

I don't have a good antenna and end up with a lot of these very low quality SSTV images.  Some of my friends think I looking at static and making these things up :)  Can some people please reply and acknowledge that there indeed is a deliberate image here and not just static.

Thanks

Nothing at all on my overnight SDR recording.

Any chance your decoder just triggered on some random noise?  I don't really see anything in the image. Or is this some sort of psychological test?  ;D

This isn't a test.  Look at the picture and move your eyes form the top to the bottom to vary the lighting.  This will make it easier to spot the figures.

Do you have an audio recording of the SSTV transmissions? What were you using for a radio and antenna?

Unfortunately no recording.  My radio is an AOR 8200 MK 3.  I was using a stock telescoping antenna with 20 gauge copper wire wrapped around it and the other end twisted into one of my radiator grates. I have an indoor amplified antenna (can't find it for the model #) that doesn't get better reception than that setup.
