Is there a device out there that can amplify the FM signal that my receiver gets?
Yes. You can use what is known as an ‘active antenna’. This is a device that incorporates both a passive antenna and an active electronic circuit that amplifies the signals received by the antenna over specific frequency ranges. You don’t get something for nothing – boosting the signal strength also increases the signal noise. You might be better to use an external FM antenna instead of the wire loop antenna usually provided with receivers. The best antennae location is on the roof and oriented to maximize the signal from those stations you are interested in hearing.
