Pay particular attention to the rev counter between 6 seconds a 10 seconds running time....

Back then the TV rev counter worked by interpreting engine noise, not via telemetry from the teams. That's why it reacts to the audio breaking up, it's nothing to do with TC.

I thought they still did?

I will watch the vid when i get home from work.

Thats what I think it is.

I agree

That video Phoenix, is not a TC car. Thats either 2000 or 2001. TC came back in at the Spanish GP in 01.

And, the rev counter is reading the sound signal to determin revs. The interference is causing it to cut out.

Try again.

I don't remember where I heard it, but I think it was mentioned that it's telemetry now. Don't quote me though

Interestingly the engine note change matched Hiedfelds KERS usage perfectly today, Brundle even commented on it at the time.
