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.
