Help creating a working chain... about csdr

[ha7ilm]

I can't try it, anyway I guess that:

elad_sdr_24 7070000 0 | csdr convert_s24_f | csdr shift_addition_cc $(python -c "print (7073000-7070000.)/192000") |  csdr fir_decimate_cc 4 0.05 HAMMING | csdr bandpass_fir_fft_cc -0.1 0 0.05 | csdr realpart_cf | csdr agc_ff | csdr limit_ff | csdr convert_f_s16 | mplayer -cache 1024 -quiet -rawaudio samplesize=2:channels=1:rate=48000 -demuxer rawaudio -

There might as well be an endianness problem, which can be fixed with csdr convert_s24_f --bigendian.

I'll try asap and let you know.
Please, can you explain where is the audio bandwidth calculated? (I mean
the 2.3 or 2.7 khz... cannot remember the ham standard)

csdr bandpass_fir_fft_cc -0.1 0 0.05

...will have around 4.8 kHz.

csdr bandpass_fir_fft_cc -0.05625 0 0.002 

...will have 2.7 kHz, with a transition BW of 96 Hz.

I hope it is solved by now.
