Mike, the Radio-Locator maps are fairly accurate concerning 97.5. Unfortunately 1/2 the signal goes over the lake, so the fish and boats can enjoy it.

Between the Purple and Blue contours, within the NW and W suburbs, it is bouncing between Chicago and the Rockford signal in a car and not listenable in houses unless they employ and outside antenna. Purple contour is solid in the car. Red is solid in the car and in houses, except close to the transmitter, which is common with all signals by the lakefront or tall buildings.

The signal was in mono all day yesterday, when I heard it on the outer Purple contours. I am surprised Jeremy can hear it to the North, I have a feeling the signal favors the North and South more.

The HD3 in the car has a very similar pattern and in the West suburbs starts dropping out around the Purple contour and gone at the Blue contour.

The EMF Air1 WSRI-FM Sugar Grove IL @ 88.7 would possibly be a great extension for BOOST into the West/SW including the college town of DeKalb, if they are looking to lease it. They already have 94.3 their main signal for AIR1 and this is an overlap.
