A few DHL's in a hold due to "moderate" ice pellets and at least two flights cancelled by, "company", as they were taxing out... It has been an interesting night to listen to the chatter. Unfortuately, with the ice pellets, a new report of considerable windshear off the west side of the airport, and the poor braking conditions on the runways, it's now getting really quiet. (Except for the sound of ifr flight strips hitting the trash cans in the tower!)
I will look into the maitenence and ramp frequencies in the coming week. I am also trying Indy Center freqs as well.
