commit e4b89a11cb942ca0ee4bc7908457f2a5eae6848b
Author: Sylvain Munaut <tnt(a)246tNt.com>
Date: Sat Apr 4 22:53:44 2015 +0200
gr-gmr1: Switch the 'freq' tag to be in Hertz
This also required adapting the file_sink. It now has an option to
specify if the spectrum was inverted or not. It's necessary to know
if the received frequency has to be added or substracted from the
center frequency.

gr-gmr1: Tighten the low_pass in gmr_rach_scan
30 kHz is more than enough and helps get rid of adjacent bursts better

commit 46eee3c8fb7364b13f0c301281ced87059dcfb4b

gr-gmr1: Change freq_offset to peak_freq
This represents the frequency of the expected peak compared to the center
of the burst. This is also the frequency at which the peak CW will end
up at at the output.

commit 31394e9be9cd5839a5a2b04a828de9a701c65953
Author: Sylvain Munaut <tnt(a)246tNt.com>
Date: Sat Apr 4 18:13:19 2015 +0200
gr-gmr1: Make rach_detect_fft use sample_rate instead of fft_size as param
The is really no reason to use any other fft size than the auto computed
one and having the sample_rate will allow the output frequency to be
in hz rather than radian.
