I am hearing nothing for the departure feed, but I can hear airplanes talking on the arrival feed, not any controller. (No big deal better of course than nothing!)
A departure feed would be nice to have up and running, and there is another ground frequency that some are being handed off to that I cannot hear. I don't know the frequency but mostly for airplanes north of 30R like skydubai.
126.20 is the freq that departures are being handed off to after take-off.
