Do you have an SWR meter? Or a friend with an antenna analyzer? High SWR can lead to a lot of RF in the shack. When you wrapped your choke I see you said you used a coffee can. Was it metal? If so, take it out. And you likely need more turns, try doubling them.
On another note, looks like all your connections are not wrapped with tape. Moisture can cause SWR issues as well, aside from killing your signal.
Good luck!
