Re: Stress?
Many years ago I worked in an F1 team, doing telemetry (HQ and test track based not travelling with the races). I got the job because I was an active radio amateur and I knew the people already there (who were also radio amateurs). We would attempt to pickup a batch of packets as the car passed the pit wall and would get them perhaps on 1 out of every 3 passes.
Telemetry was in its infancy then, and has moved on exponentially since, gone way out of my league now.
