UMKA-1 telescope satellite mission

Hi Aleksey,

Are you sure about the time?

On r4uab.ru it’s:

Окончание передачи: 15 февраля 2025 года в ~ 07:40 UTC.

I believe the event was extended, because today UmKA was without SSTV transmission for a while.

(It was shown here in Brazil this morning with SSTV turned off)

It’s just my guess heheehehe we’ll see @ra3ppy answer

Hi Daniel. I set my own time. :sweat_smile: I will correct the time on the r4uab.ru resource. It was decided to extend the broadcast due to a scheduling error.

There are problems logging into this forum. It is not always possible to notify promptly.

Thanks to Alexis (@ra3ppy) / the team for extending the activation period. I too had problems getting on to the forum yesterday morning (SSL Cert issue?) and would have missed this had it not been extended.
Got 3 copies of the same image … this by far the best (almost as good as Daniel’s :slight_smile: )

I have done some research on Saudi Arabia’s founding day and learned that there are attempts to rewrite the true history. I do not want to support that, so I have decided not to publish the received images.

Received 4 images (same 4 as Igor @PU4ELT posted) during the 0924UTC pass over UK. Visiting family so just used a HT / mobile phone to capture recording. 2 reasonable images in the middle of pass with noise/degradation to 1st & 4th but still acceptable considering limitations of RX and antenna.

Is this address used for all UMKA-1 QSL requests? Can it be used for today’s activation?

You may use this address for all requests. However the UMKA-1 team does not offer QSL cards for all activities.

As far as I know, there is no QSL card planned for Saudi Arabia’s founding day.
