Well, there it goes. Today, the 19th of August 2025, NOAA-15 was decommissioned over svalbard. I didn't manage to get the final APT, but this time meti from the satdump discord (and some others) did, and is the picture attached to this post.
Here is a link to their archive website licensed CC-BY-SA-4.0 received by meti.

Earlier, (the svalbard pass before?) the AVHRR patch cooling was disabled, making the IR channels unusable and white on the APT.

With NOAA-18 and NOAA-19 having been decommissioned earlier, as I have made posts about. This is the end of 137MHz APT, but meteor LRPT is still active, and is planned to continue for many years.

Although old, I found APT fun to receive, with it's rhythmic clicking, and analogue images. If anyone is even in this community maybe post your best APT receptions in the comments.

I was never particularly good at it, but I really enjoyed it. I have fond memories of carrying an antenna around the room trying to chase down the strongest bit of signal, not to a great amount of success.

So long APT, I will miss your song!

There is always LRPT to try!
