I picked this up 5:13 P.M. UTC 04/13.  I have a 3 foot stock indoor antenna in a city apartment, so I consider this great reception:

I got a worse quality version of the same image at 2:14 A.M. UTC.




They must be BLASTING the signal, as I received it in a city apartment with a stock telescoping antenna.

Thanks for info. I have a lot of fun receiving the station SSTV on a scanner and Chris' CQ SSTV app on my iPhone. The neighbors are always amazed.

Np

To decode SSTV signals, I normally connect my radio to a Windows Surface Tablet by an audio cord.  If don't know when a signal is coming (shortwave stuff) I just leave the MMSTV app running and it automatically decodes the signal and saves pictures in its directory.  If I know within a reasonable time that a signal is coming, (Like when tracking the ISS) I just leave audacity running and record the signal.  I can then clean up with signal a bit before running MMSTV.

For when I go outside to get a better signal, I'd like to directly connect the radio to my iPhone (7 with the lightning port) with an audio cord, but don't know what kind of cord to buy.  Do you use thsi kind of setup, or just play the audio into the iPhone's external microphone?

I picking up Alex Jones and his "Infowars" show on 4840 MHz AM.

Blasting 100W from Nashville Tennessee to my Living Room in NYC.

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.

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.

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

You are correct,

I had initially reported the find two hours early because a different forum that I posted my find to is time stamping my posts two hours early, so I heard the signal around 0400.

My radio is a drop off so I accept the fact that the signal was in fact coming from 6105.

Thanks

I need somebody who understands Japanese to answer this:

On October 21st at night (around 2:00 A.M. UTC), I picked up a good shortwave signal at 6100 kHz.  I don’t speak or understand the language, but the announcers are clearly speaking Japanese and it appears to be coverage of an MMA event.  Can somebody confirm this and tell me what event it was.  Also, WTF was it doing on shortwave radio?  Was it a legal broadcast or some sort of illegal audio stream?

At first, I thought it was Korean as internet resources (https://www.shortwaveschedule.com/?now=true) stated that the signal was from KCBS Pyongyang in North Korea, but the spoken voices are clearly Japanese.
