UmKA-1 (RS40S) The SSTV activity on August 25-26. At 9:10 PM on August 26, I happened to see a message and went to the nearby small park to try receiving it. It was cloudy with an angle of elevation of 70 degrees, but I only received one image because the satellite was close to setting down.
The equipment consists of an RTL-SDR Blog V4 and a five-element Yagi antenna. I downloaded the Stellarium software, along with automatic Doppler compensation. The surrounding area is relatively open. The signal sounds quite clear, but there's still a lot of noise. I don't know where all the "clicking" sounds are coming from; could it be that the gain is set too high? I'm holding the laptop in my left hand and the antenna in my right, and as soon as a signal comes through, I can't adjust the parameters on the SDR software. The operation is very inconvenient...
