Your HF you can force-feed inbetween the tuner-chip and the RTL chip if
you got a bit of LNA to get the swing up. There are some tuners that has
a bypass option to enable. The RTL has a limited tuner itself.
There is a few interesting software and hardware hacks. It's quite
capable platforms, considering that it was intended for a different
application. :)
