Sorry, but, I doubt that any userspace application developer will find those descriptions
useful.

For the threshold: I understand that this is the carrier strength used to detect a
channel, right? If so, please improve the description.
Also, The better is to associate its scale to a carrier level in some unit like dB.

The second control means absolutely nothing... It is not a boolean value, and what
is "alternative" frequency mode?

Cheers,
Mauro.
