What frequency are these images being sent on?
Higher up the thread people were asking about 10ghz. Is that the right band or is the 70cm frequency used?
Just listened on 70cm and thought I could hear something in the noise but maybe wishful thinking.
Don’t have 10ghz capability but if 70cm is used might download a decoder and try with better setup over weekend.

Follow the observation link and you will find 435.8720

Thanks @PE0SAT didn’t think of that.
I’ll download a decoder or two later and try to catch a couple of the passes over the UK.

Got my first picture from TK1 from observation satnogs_10745829_2024-12-11T19-50-54
On linux - used gr-satellites then stratosat_simple.py.
Is there a more effective workflow?

Well that’s a bit of a disappointment. Downloaded, setup and tested the decoder with an audio file from the database. All worked fine.
Now checking the schedule none of the upcoming transmissions are while the bird is visible to me.
Today my passes were /are 0940z & 2018z neither of have scheduled tx. Last night 2040z was also just after tx stopped.
Oh well at least I know my should work for the next time.

My next opportunity later tonight

about 40 minuets ago I saw the last pass but was not able to get all the data so no image

But the schedule doesn’t show tx at that time does it?
Image 20 tx stops at 2002z
Nothing was scheduled on the previous pass either. First image today image 16 @1145z.

tonight I should get image 15
