This was a social day in Hackney Downs! I was approached by two men and their dogs, and speaking to them took up most of my attention during the pass. The first was an older, very large man named Bill and his dog nutmeg, a medium sized, curly haired deep brown dog, maybe a kind of terrier. The second was a younger man with a very big and wide laborador. Bill told me stories of his father who had used radio during WWII to listen to the Germans, and later erected aerials at racecourses across the UK (for reasons I didn't entirely understand). He also told me about a lecture he had attended by someone called Chris Lintott that was about microwaves and radio astronomy. The second man whose name I didn't catch had set up an antenna on the roof of his second floor flat to listen to ADSB. He mentioned he had gotten a dipole and tried capturing a satellite image but was unsuccessful. He also asked if I was into amateur radio and when I said yes, he said 'you and about five other people in the world, right?'
