5G (?)
(From MorseCode to MeshTelephony)
On the topic of Free/Libre RadioElectric Spectrum, we will demo a #mesh network node to allow the use of telephones (be them mobile and/or fixed) outside "telecommercial" infrastructures. Defining 5G as the moment when we get rid of the telephone company. As seen with the bricolabs #bricophone project.

14:28 < charolastra> i'm analysing a remote controll for a R/C truck from the 80's. it seems to just play tones over an AM modulation: http://imgur.com/gv6PZ (sequence is forward, f/l, f, f/r, f; and again with back) what i don't get isharmonic tones are mix and why the singnals for left/right only differ by a few Hz
14:42 < HJ4ADJ> charolastra: how do you hook the transmitter to baudline?
14:42 < HJ4ADJ> i guessing is through sound card..
14:42 < HJ4ADJ> i'm^
14:43 < charolastra> in this case it's just a .wav recording from gqrx
14:43 < HJ4ADJ> i see
14:43 < HJ4ADJ> i/q
14:43 < HJ4ADJ> nice, thanks
14:43 < charolastra> but i think i once did it with JACK and sdr#
14:44 < HJ4ADJ> i have to check sdr#
14:44 < HJ4ADJ> was not aware it had jack support
14:45 < charolastra> i guess it's native for mono or something
14:45 < charolastra> if you want a high speed display of the baseband try this: rtl_sdr -f 92200000 -s 1000000 -g 0 - | ./baudline -reset -samplerate 1000000 -channels 2 -format u8 -quadrature -stdin
14:46 < charolastra> even faster: rtl_sdr -f 164000000 -s 2000000 -g 27 - | ./baudline -reset -samplerate 2000000 -channels 2 -format u8 -quadrature -stdin
14:51 < g0hww> i didn't know you could do that with baudline :)
