I remember at the time having trouble receiving WHRB in Bedford.  I didn't 
understand such things that well in 8th grade.  I knew from the newspapers 
that a station was there, but I couldn't receive it.  Once, I got WHRB 
just barely at 107.1.  When I called the station to ask about it, they 
said it was because of interference from WBZ, and they were going to move 
to 95.3 soon.

When they moved to 95.3, I still had trouble receiving them, although it 
was slightly better.  I could receive them, but it was a real struggle on 
the radio I had then separating them from WKBR-FM on one side and WMTW-FM 
on the other.
