Create signal from frequency selection (Spectrogram) #344

Closed vsboost closed 6 years ago

vsboost commented 6 years ago

Create signal from frequency selection is not working as expected.

Selecting the top fsk signal and creating signal from selection displays both top and bottom signal. image Selecting the middle fsk signal and creating signal from selection displays only middle signal (good). image Selecting the bottom fsk signal and creating signal from selection displays no signal. image Have played around with the bandwidth settings but it does not help.

Windows version. Universal Radio Hacker Version: 1.8.10

Could you please upload a sample of your signal so we can have a deeper look?

Thanks, brickwall filter works a treat.

Update on this: I fixed the default bandpass filter in a20ddb1d33c9c7e7d7a369cec90ff71af4587281 so it can also handle negative frequencies. Brickwall Filter may get removed soon due to bad performance.

No probs, look forward to testing it out.
