Manual Radio?

Hi, "Automatic Channel Search with Signal Quality Evaluation, Automatic Noise Suppression" ...is it also possible to adjust the tuning manually, in order to find also any in-between-stations and slightly-out-of-tuning magic? If it is, at what frequency resolution per button click? If not, is it possible to hack into that, or doesn't the FM chip support it at all?

Thanks,

PS. As a sidenote, I also recall that at least way back in the days, the AM, long wave and other bands was full of far-away-from-home broadcasts, which could perhaps be even more interesting for sound harvesting than the local FM band, if they are still there... Radio^2? :)
