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.

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

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.
