Unfortunately, the ISS SSTV transmissions scheduled to the next weekend had to be canceled. Anyway, I'm planning to capture some images and have a doubt. I've been trying to find some answers, but no success this far.
My doubt is: during the days of the transmissions (let's suppose, the next saturday and sunday), do the transmissions usually happen continuously, or they happen at specific times (For instance, at scheduled times or while the Station is passing over specific countries/regions)?
Putting it in other words: may I expect that the Station will be transmitting during all the passes over my QTH, or I would have to be a little "lucky" to have the station transmiting something while passing over my location?
