Suggestions Please . . Picky Tuner

I just bought a Parasound t3 tuner to replace a 40 year old Fisher tuner.  The sound is improved but there is a curious problem:  I have it connected to an attic mounted antenna via coax and it pulls in distant FM stations (50-60 miles away) but struggles to bring in some local stations.  For those, there are static sounds and fading in and out.  I would think the opposite would occur — get the local stations but not the more distant, as it was with the Fisher.   Do you think the tuner needs to be cleaned or is there some other problem?   Otherwise, I really like the Parasound and just want to get the local stations clearly as well.
