Can an FM Tuner be "hot-rodded" long distance???

I was advised by a 'GON member that some tuners can be modified to improve long distance performance. I have a Mac 1700 Receiver, and Fanfare SC-1 indoor antenna which has helped, but I can't mount the whip antenna on the roof or a pole on the roof because I am in an apartment complex. The stations I would like to receive are in Los Angelus county which is approx 130 miles away... With my current set-up, I can get one station,but it is weak and noisy. All advice appreciated!!!
