for that MK5, I suggest to remove it completely to stay at some old
rules we did not ship with that bad so far.
We can change the UHF switch on the tuner 38 for that 1 MHz, it will not
cause any trouble, but that new entry only causes confusion and 0xce
should even be wrong for an FM tuner.
Dmitry, defend your stuff, if needed.
