This Saturday, the SHKT team invites radio amateurs to an unusual event.
The first gender party from orbit. Our radio amateur brother and his wife are expecting a baby. They don’t know the gender of their baby yet. But UMKA already knows what he intends to announce from orbit on March 29.
But it’s not that simple. Since UMKA and the SHKT team love astronomy and the mysteries of the universe and in general (the black squares won’t let you lie), the message from orbit will not be unambiguous. The answer will be encrypted in the image. Not very difficult. But you need to think a little.

The transmission of one image will begin on March 29 at 00:45 UTC
The transmission will end on March 29 at 08:45 UTC

  • Frequency - 437.625 MHz
  • Format SSTV Robot36
  • Intervals - 144 seconds

Unfortunately, I only have a 2.8 degree elevation pass for my QTH here in Brazil :cry:

(it’s impossible to receive anything due to the mountains to the west that limit me to at least 5 degrees)…

Same problem here. The only half decent pass is 8:38 UTC and most of it is behind the apartment block i live in.

Cant win them all i guess.
