Should I use the graph on top to decode the signal? I tried to use multiple programs but they all had the same graph like the one at the bottom. I am not sure about the accuracy of the one on top
Since it is only showing 0, change the noise ratio, and it will get a lot more 1’s in there.
Where did you get the graph? It contains quite a lot of levels, while Flipper’s radio is strictly binary.
RTL-SDR USB v4 to get signal
SDR# to record
URH to decode
Goal: decode, regenerate signal, use flipper to transmit
Original flipper antenna is not strong enough to record the signal in detail, especially when it comes to some specific modulations
try recording it with RTL433, it makes nice cu8 files from capturers
if it is recognized, use -S known
if not recogniced use -S all
for save
other commandline options you need are verbose -v ofc, and -f 868M for frequency if you need others then default 433, and if you do not like the default samplerate you can go big with -s 2048K for example.
it will cut it into nice cu8 files for you , it will also be a lot more easy to cut / edit and convert to sub.
