Tuner drivers
=============

Simple tuner Programming
------------------------

There are some flavors of Tuner programming APIs.
These differ mainly by the bandswitch byte.

- L= LG_API       (VHF_LO=0x01, VHF_HI=0x02, UHF=0x08, radio=0x04)
- P= PHILIPS_API  (VHF_LO=0xA0, VHF_HI=0x90, UHF=0x30, radio=0x04)
- T= TEMIC_API    (VHF_LO=0x02, VHF_HI=0x04, UHF=0x01)
- A= ALPS_API     (VHF_LO=0x14, VHF_HI=0x12, UHF=0x11)
- M= PHILIPS_MK3  (VHF_LO=0x01, VHF_HI=0x02, UHF=0x04, radio=0x19)

Tuner Manufacturers
