Compare FM Pattern type to realtime

Post by watchix » Sat Jan 16, 2021 10:33 pm

Hello from France,

We are having trouble with our FM transmitter sometimes it just freeze and needs to reboot.
We can do this reboot remotely.

When our transmitter freeze, we can "hear" a white noise, and see this pattern with GQRX Image

At next freeze i'll record it with this command as RAW data with :

Code: Select all

rtl_sdr -f 110000000 -g 10 -s 2500000 -n 25000000 Capture.dat 
Now my question is : is there a way to compare the current FM reception to a RAW file, and then send us an email alert ?

Regards,

Watchix.
