It's a free service we can use, as long as we agree to include the 60 to 90 seconds of commericals in the broadcast.
We tried it early last year and I really liked it, but it was too much time wasted since it ran every hour.
Right now I'm testing it, trying to get it to run every three hours. If it works we would have news updates at 6 AM, 9AM, Noon, 3 PM and 6PM. I'll also set it eventually so it runs as close to the top of the hour as possible.
