I know this error is unchecked but one of the busiest frequencies in the country. Chicago App Sector 2 i.e. west of ORD and MDW directly over KDPA KLOT KJOT from sfc - 6k’ is 128.2. In MSFS2020 the freq. is 126.7 which is RFD atis.
Now imagine ORD doing a 50+ arrival rate and your trying to get atc in between atis information readings. Fml.
