Postcard from the ISS

pictures of satelliteThis weekend, Russian-ARISS transmitted SSTV images of satellites hand-launched from the ISS. They used a high-resolution mode, PD-120 transmitted FM on 145.800.

I was set up for FT8, but switched over for one pass and captured this image. My process for decoding was suboptimal — I recorded using audacity on my Mac and then later played the audio back to a PC set up with MMSSTV. I didn’t have an attenuator on hand, so of course the sound level was high for the PC input, but was able to drop the gain a bit in audacity. Maybe I traded off a little image quality, but it worked.

This was a low pass (max elevation of about 12.5 degrees) on a side where I have some obstructions — those horizontal lines are probably tall trees —  so probably not the best image I could have captured, but I was just curious if it would work at all.

I’ll be squeezing out what QSOs I can on 17m FT8 through the end of July 4th and will then swap in a 30m element on the antenna for the next couple weeks.
