Weird Signal

[Hotshot7966]

Hi everyone,

I'm using an RTL SDR v3 and a weird signal is always present at the center of the listening window at full zoom out, on an M1 MacBook Pro with v1.2.0.

I have a recording but it won't let me attach it, I've got a couple of screenshots of the waterfall below.

Thanks,
Charlie

That's the IQ spike at the center, turn on IQ Correction to get rid of it, you can also use the correction to get rid of carrier waves that are much stronger than the signal
