The Russian Embassy is pretty close as is the Chinese. That said, they could easily track military helicopters with or without ADS-B Out.

Easily? I suppose a surveillance radar on the roof of those embassies wouldn’t go unnoticed.

    American embassies do this worldwide, famously spying on Angela Merkel from the Berlin Embassy (probably). [1]

      And how exactly does it help Russia to know there are planes and helicopters flying in the US around an airport

      What's the next conspiracy? They have anti air weapons in embassies and wait for a military helicopter transporting a high value target?

      Either way it's not worth 64 lives...

    Passive RADAR is an incredibly cool technology. Instead of the RADAR station transmitting its own signals, it relies on nearby high-power cultural transmissions (FM radio, broadcast TV, etc) as the signal source and measures the reflections of those signals off of aircraft. Since the majority of traffic in the region would be broadcasting ADSB, you'd be able to figure out which tracks from your Passive RADAR system correspond to aircraft without ADSB.

    You don't need radar to track aircraft with ADS-B on: The plane is actively broadcasting its position.

    There's ADS-B receivers the size of a USB stick - because some are USB sticks and available for 50 bucks on Amazon.
