One thing I thought you were running into was the fact you were
tuning to an even frequency of a station. In the States they are
all odd, ie 95.7, 95.9, 96.1, etc. Then I noticed you domain is
in the UK were stations are on even frequencies. Oh well...
What happens if you run without AFC, and in mono? Can you just
plug into the output of the Tuner card with head phones? What do
you hear?
