Believe it or not, I have never heard WSLQ in northern VA despite its huge, monster 150 kW signal, not even in tropo conditions.
I'll want to be on the lookout for WSLQ, having heard some VA, MD, DC and NC stations in recent years summer DXing! Looked up WSLQ 'specs' on radio-locator and FCC, R-L indicates CP to go to 191kW and FCC says 200kW. (or has it really been 200kW, not 150 kW?) Didn't know stations could raise ERP even if they are lowering the HAAT of their antenna array...Not that more power is really all that necessary for Tropo or E-Skip. Got KVOD from Lakewood (Denver), CO with its 1.2kW through the rain at my location (NW suburbs of Chicago, about 895 miles) a few years ago!
