...I was just thinking about the radio aspect this morning. Do we have any idea what frequency they might be using?
Most of those helicopters were mosquito control. A number of the TV branded helicopters are operated by Scotts Helicopter Service who uses them for their mosquito control contract. There has also been a lot of Army guard, State Patrol, and Life Link training flights in the past few weeks.Viewing Flightradar24 I see 5 helicopters hovering around the perimeter of the Metro- I know at least some are the branded TV station helicopters.
