ARINC - O'Hare International Airport - Chicago (DMR 407)

Has anyone within 10 miles of O'Hare been able to tune into this ARINC system? I'm using SDR/DSD+. I appear to have a good signal but I'm missing many calls. Has anything changed with this system?

Uniden SDS200 and Uniden 536hp sounds good on both

I'm monitoring via RTL-SDR and have confirmed that the the site and frequency files are correct according to RR. There is a chance that I am out of RX range for this system, but according to what I see I am getting a good strong signal. I'll need to revisit my configuration.
