Tetra signal detection #2134
Comments
Technically for that we need to calculate spectral density in known freq band or on desired freq (if you know the neighbor TMO BTS freq, like 390.200 DLINK, 380.200 UPLINK). All Tetra mobile radios in TMO mode periodically send the signals on uplink freq (380-385). Different sync signals and frequency correction bursts (actually CW carrier very short in time). No need to decode tetra constellation for that. Only the basic FFT calculations. |
Really interesting! It would be an amazing addition to this great hardware. I would personally chip in at least 50$ for someone that delegates his time to implement this |
Such an app would be wunderful 🤗🤗🤗 |
A python code that does exactly this. https://github.com/NukeAlchemist/blupi/blob/master/blupi-scan.py @htotoo Is that something that you would maybe consider? I would gladly support this addition, maybe there is a way to start a tips jar for a project like this? :-) |
Description of the feature you're suggesting.
It would be awesome to have an app that notifies (with a beep) when specific signal power rises
In this application it is used to notify nearby ambulance/firefighters/police vehicles

Basically it could be as an addition to the 'level' app, only need to configure thresholds for different sounds
Thank you
Anything else?
