WSAR has decent coverage, but the transmitter is just in a weird spot. You can get a signal in Attleboro, Tanton, Brockton and even Providence. But it's one of those static filled signals which just gets annoying to listen to for more than 5 minutes at a time. You really need to fine tune your radio by twisting and turning the unit to get a decent signal outside of the immediate Fall River/ Somerset area.
I was driving to see David Letterman one day and I picked up WSAR at Exit 93 'first exit into Connecticut" over the Rhode Island border. But that was the absolute limit. The static filled signal just died after that.
