Also the level 8 can be selected. Actually level 6 is selected, but
reduced to 8 when making a call.

Andreas Eversberg c2f14834e5 Rename dbm0 (level) to speech (level)
In mobile communications we use speech level instead of milliwatts.
The deviation (FM) is always based on speech level, not on 1 milliwatt.

Andreas Eversberg 360729d270 C-Netz: Added list of base station names and IDs
Automatic polarity detection is now done by using the polarity of last
transmitted message. We cannot use two base station IDs anymore, to
detect the polarity. Now we deal only with the defined base station ID.

Andreas Eversberg 31fca59294 Fixed performance issue with IIR filter
Passing samples with zero value (0.0) causes very slow processing of
IIR filter on my test machine 'nuedel'. I don't know why.
To solve this, I add a very small number to each input sample.
