Signal Strength #203

Closed mmiller7 closed 2 years ago

mmiller7 commented 3 years ago

Is there an option that I'm not seeing to have signal strength (RSSI, SNR, anything) dumped for each record?

I'd like to be able to compare different antennas and locations to see the best to use but I can't find any way to figure out how "good" the signal is that its decoding.

Getting "real" values for RSSI or measuring SNR is relatively complicated and not included in rtlamr. I would gauge signal strength based on the number of received messages over time.

You can also use -samplefile and manually inspect received messages relative to the noise floor.
