Yep, nice one. Perhaps just a touch too much high pass filtering, but great data by the looks of it.
Re the G20, it was interesting after about 1am last night - could hear the sound of military jets at high altitude every 15mins or so - fighters perhaps circuiting the city above 10,000 ft? When I first heard them wondered if Airforce one was making an early arrival.
I couldn't help wondering what the choppers have thought about my scopes point up towards them over the last week or so.
