2nd referee signal end of timeout

[Antonio.King]

My process is as follows:

A short and long whistle to start (tweet tweeeeeeet), and to end, one long whistle (tweeeeeeeeet). The rationale behind using one long whistle to end, and I agree, is that you're essentially taking the the place of the horn ending the time out.

I've heard her rationale before, and I think this is one of the many techniques where you'll always hear differences. What's most important is that you differentiate the tone so it doesn't sound like the service whistle.
