I'm wondering what antenna you're using, and whether it is polarised correctly to receive your preferred transmitter.

In times-past (1970s) I used a FUBA UKA8 with a rotator - it was horizontally-polarised. These days most FM transmitters are either slant-polarised (the main BBC/commercial stations) or vertically-polarised [the rather-more-listenworthy licence-free stations with transmitters on top of tower-blocks].

Choose your polarisation according to your taste - but always remember that directional antennas provide 'free' gain - which comes without amplifier-noise, and can help exclude 'multipath' background-twitternoises off the back of the beam.
