Which tuner to get and getting the most from it. Thank God, for the radio!

Multipath.

Good FM reception with truly good sound in stereo requires

i) a signal strong enough to fully quieten the front end of the receiver, and

ii) a signal as free as possible from multipath reflections (from hills, towers and high rise). Multipath that will be audible, can't be dealt with by FM front-ends.

Even car radios will splutter when behind a hill or in a city full of office towers. But mild mpath causes the sound to deteriorate long before spluttering.

This second requirement may need a directional antenna. Directional means that it can pick out the best possible signal. It will also give you signal gain.

FM's lambda is ~ 3metres / ~11 feet. So, truly good sounding FM from a good FM tuner can't always be achieved with a small antenna. Particularly so in hilly urban areas.

My favourite station - the strongest FM signal here* - is transmitted from two hills (*Canberra, Australia.) In the car I switch from one frequency to the other when I'm blocked from one site or the other, almost every drive. And multipath is the reason.
