I'm curious, where in California do you use Ham radios to talk to helicopter pilots in an emergency? What county is this taking place in?
I guess I'm not in the norm so I better provide an example.
Real life drama from last year. It was about 9 pm when a guy in a pickup got out of his truck to check a big drop off that was in front of him. The vehicle started to roll forward and he got caught in the door and the vehicle rolled on top of him causing major injuries. Some in the group started on first aid while another ran down the trail looking for somebody with a HAM radio, as there is no cell Ph service to call for help.
The HAM radio operator was able to get a hold of other HAM operator that is a SAR veteran and they call in for a life flight helicopter, to rush the young man to the hospital. Since they were off road the helicopter just can't land anywhere as it's hilly, brush covered, trees, water, etc. They gave there general location and a second HAM operator knew of a GPS location not far from where they where to give to the life flight folks. The problem is the lading zone is still very small and its night time. The HAM operator in the field can help guide the pilot in. Remember they are going fast so it easy to over shoot the GPS location and time is of importance. The HAM on the ground makes sure everyone has turned off there lights in the area and only he has a light. He talks with the pilot letting him know he hears him coming, and pilot will respond as he sees the light. The next thing is you need to provide hazard information, like large tree to the north. They also like to know wind direction. We carry a small strip of flagging tape. Once they get close they turn on there light. You also need to make sure nothing is around to get sucked up. Like take your hat off if your wearing one. No tents near by,etc. If something were to get sucked up the pilot would have to call for back up and mechanic to check out the engine( i.e. not a happy pilot)
The young man's life was saved. As to his recovery, he had 9 broken ribs, puntured lung, bronken shoulder and a concussion.
FWIW only the CHP helicopters have a long line so they don't need to land.
I can't find the news article at the moment. It was back on 8/22/2009 or 23
