When it is time to shut off the second jammer (the one that is in the club), fly up to the club. Feel free to clear the outside, but you don't need to go inside. Then go back to the hospital(the location of the first jammer), and fly around the outside until you find a ledge that has two trees on it(it is pretty low on the tower and can be difficult to spot).
