As long as we're going to wish for the moon, a mic at the starting line and a mic at the finish line - few seconds of the start mic during the launch, start mic off, radio comments, few seconds of the finish line mic of car/motorcycle going through the traps , finish line mic off, radio comments.
Well, yes. That would be beyond cool!
But . . .
Logistics rear their ugly head.
5200 feet of microphone cable is a little pricey, and you'd need a pretty substantial spool to roll it out and help spooling it back up after the event.
Routing the cable in such a way that it isn't a trip hazard is a concern, and I don't think we want to sink telephone poles along the track.
Most commercial
wireless microphones have an operating circumference of about 300 feet. Anything with a longer throw is going to require some sort of FCC licensing. Don't forget that the batteries will get you about 3 hours before they'll need to be changed out.
Someone to operate the mixer to switch between the sources as you described - while an elementary task, is going to require
someone to operate the mixer to switch between the sources as you described.The moon? Give me NASA's budget, and I'll make it go.
But for now, I'm just pleased as punch that the whole deal pulled off as easily as it did.
To Gregg!
