Don't know if you've checked out the coverage maps, but there are two HUGE nulls to the NW to protect their 88.5/C'ville and 88.7 in Warrenton. Also another to the S to protect WRIH in Richmond, and a little null to the N to protect WAMU.
I'm almost convinced they are not anywhere near full-power yet. I'm 12.5 miles from the tower site and can pick up WAMU (at 50 miles) better than the 88.3 signal
Sounds like you have a good setup for FM though so you may get lucky.
And in case people care, there is currently little to no signal in Downtown Fredericksburg from the station. Station is in mono, but it has gotten blasted around town at night by 88.3/Ocean City and IBOC from WAMU.
