+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)
