but it depends what you want to use rtl_sdr for. do you
want it for less
system load, or do you want it to have remote control over the receiver.
in the latter case you can control gnuradio via http. i can post a
gnuradio flowgraph that i use for scanning tetra networks. the frequency
is controlled via http from a modified version of telive (scans the
frequencies and logs the network parameters it finds)
I want remote control over the receiver, I need change frecuency for a smooth fine tuning
control with a mouse wheel or a Griffin PowerMate knob.
I'm developing a multithreading modified version of tetra-rx, this branch has 64
priority queues with the logical voice channels from Sylvain's patch, these queues
(producer thread) feed another thread (the consumer) that decodes audio and send to a fork
process (aplay, at present) to speaker.
Consumer thread supports wav recording (mp3 in near future) and float_to_bits and tetra
codecs are integrated into the main c program.
At present, I'm using a fifo for feeding from python demodulator, but I need frecuency
control for manual fine tuning and scanner modes.
My goal is making a all-in-one app programmed entirely in c and the main problem is the
python demod.
Thanks for your attention.
Best regards.
