For all my good friends up in the Chicago area that belong to the CARMA group, here are two new ATC UHF Milair frequencies. They have either changed to these new freqs or are about to change to them at the Chicago O'Hare International Airport (KIAD).
226.6750 Ground Control, ex-348.6000 MHz
348.0000 Tower, ex-390.9000 MHz.
Reports are always appreciated.
