Look HERE
Well, as far as I know, the event has ended and I “discovered” something interesting.
The GALAPAGOS-UTE-SWSU satellite, at certain times, didn’t transmit SSTV because it was alternating between AFSK + SSTV transmissions on 437.050 MHz and FSK transmissions on 435.750 MHz.
I honestly don’t know how often it alternated frequencies and the transmitters (as far as I know, they are independent transmitters for each frequency). I noticed this when the satellite passed over my QTH here in Brazil “OFF” and a few minutes later transmitted images over southern Brazil and Argentina.
