The initial setting is “7.02 MHz“ and “7.20 MHz“.

DNR
The DNR setting here stands for Dynamic Noise Reduction applied to the audio
signal. The effect is similar to that of the Dolby system on cassette recorders. You
can select either "ACTIVE" or “INACTIVE”.
The initial setting is “ACTIVE“.

The de-emphasis compensates for the pre-emphasis on the transmission. The
resultant effect is a type of noise suppression. The setting options are possible

75 µs,
J17 and
NO DEEMP.
The initial setting “75 µs“.
