Many "Pedros" are famous for their amateur mistakes, including sleeping on the job, having to deal with malfunctioning equipment, patching their signals onto other stations, etc.
Sometimes on broadcasts from Pedro operated stations, the microphone is left open, and background sounds can be heard. Once a rooster was heard, suggesting that some V2 stations are in the countryside of Cuba. The audio quality from V2 stations is often very poor, indicating that most "Pedros" do not properly maintain their vintage Soviet equipment.
Lately, there have been claims that "Pedros" have been experimenting with various ham radio digital transmission modes, such as PSK31 and, in the case of the HM01 numbers station, the RDFT digital file transfer mode.
