ISS SSTV
Last week the ISS was transmitting SSTV images. So I setup MMSSTV, and my FT818 with a new colinear antenna to see if I could receive any images.
It took a couple of days before I realised you can receive signals from the ISS even if the ISS isn’t “visible”, so I ended up leaving the radio on for the rest of the week. I actually received 14 images on the 27th (UTC) over 7 passes (!).
I was able to receive 11 of the 12 images in acceptable quality. Interestingly there must be some funny relationship between the time to send the complete 12 images and and the time is takes for the ISS to orbit the earth as I received a lot of some images, and none or very limited of others.
| Image Number | Times Received |
|---|---|
| 1 | 0 |
| 2 | 1 |
| 3 | 3 |
| 4 | 5 |
| 5 | 5 |
| 6 | 8 |
| 7 | 6 |
| 8 | 8 |
| 9 | 5 |
| 10 | 3 |
| 11 | 2 |
| 12 | 1 |
Overall was good fun, even with a non-optimal high gain colinear.
