4139011a3a speed up float_to_bits 
Reduce overhead caused by inefficient call of read
for each float. Increases speed about 50x.

6430bdeb5f fix some global ugliness 
This removes a static global variable which will only work if you only
have once instance of the tetra receiver.

2ee4b4ad4d float_to_bits: Remove offset 
This is a symptom of frequency offset and it's the demodulator job to
correct this ...

Thanks to Frank A. Stevenson for noticing this legacy hack

2037ebeac6 add rtlsdr based receiver with click & tune functionality 
Call it with

 src$ ./demod/python/rtlsdr-tetra_demod_fft.py -s 1.8e6 -f 394.6e6 -g -1 -o /dev/stdout | ./float_to_bits /dev/stdin /dev/stdout | ./tetra-rx /dev/stdin

- Adjust the center frequency (-f) and gain (-g) according to your needs.
- Use left click in Full Spectrum window to roughly select a TETRA carrier.
- Use left click to fine tune the carrier by clicking on the left or right side of the spectrum.

1bc5434a99 lower_mac/viterbi: Use the high level API of conv.h from libosmocore 
It's more stable ... here we just need a flexible length, which we
can 'fake' by creating a local copy of the 'code' definition on the
stack.
