Around 8:30 PM on Saturday, I started using SSTV to transmit and receive signals from the repeater in Huizhou. After making a few comments, I stopped for a while, then at 9:00 PM, the activity resumed immediately with interference. The decoded SSTV images turned out to be pictures of people promoting urbanization and other distorted ideologies. I heard that after 10:00 PM, they also interfered with signals from Wutongshan. Since I don't have a communication group for Wutongshan, I'm asking for recommendations.
