I can't comment on 105.7 getting into Philly from where I am. But 107.1 will not be much use in the western burbs due to WKDN at 106.9. 107.1 does come in reasonably well, outdoors at least, as far down as Quakertown, in northern most Bucks county. I'm just west of Q-town and even out on the road, The Bone is not worth trying to hear. South and west of Q-town it's not worth the trouble.
