Will you be making an update that corrects a few of the ground and clearance frequencies. There is only one clearance frequency 121.6, no 119.25.
There is only 4 ground frequencies. 124.125 for the North tower. 121.75 and 121.9 for center tower. 118.05 for the south tower. The ground that you have of 121.75 is not a ground control frequency.
I looked on Navigraph and Jeppsen for the correct frequencies.
