[arm-allstar] Forecast.sh delay or pause if repeater is busy

[David Panscik]

Howdy.
I have a crontab set to fire Forecast.sh a few times a day.
The script downloads the weather report from the National Weather Service and puts the report on the air.  Its a fairly lengthy report taking approximately two minutes to transmit.
Is there a way to make weather.sh to wait to broadcast if the repeater is busy?
Ideally I would like the script to pause until the repeater has not been used for at least 60 seconds.
Is there a way to do this?
Thanks!*73*
