I have looked at the various "TAPE"-type tuners from LG and seen that
they involved patching tuner.c to have the radio work. The attached
patch is empirical and works for me. It is quite straightforward.
However I haven't found any specification detailing how to program the
tuner, so in particular I do not know if the reverse order of commands
when freq < t->freq is really needed, it seems to work without it as
well, but I followed the comment on line 938.
Cheers,
