Re: [Discuss-gnuradio] 802.11a capture with HackRF - Why am I not receiving signals anymore?

Pic of the output from the QT GUI Frequency sink is shown below. I didn't see anything significantly different from this, even when I put the radio right up next to my home router. I've been told that it would be a good idea to set a DC offset for my source, but I'm unsure how to calculate that, a

Re: [Discuss-gnuradio] 802.11a capture with HackRF - Why am I not receiving signals anymore?

Ah OK, but then it's *barely* enough for wifi. I meant that you attach a visual sink, for example the "Qt GUI frequency sink" in GNU Radio directly to your HackRF-interfacing source (probably the osmocom source?). Best regards, Marcus On Mon, 2019-08-12 at 15:27 -0400, Eamon Heaney wrote: > Do

Do you mean with a spectrum analyzer? Forgive me if that's a dumb question, I'm a bit new to this. The max bandwidth of the HackRF One is 20MHz, so I should be able to receive data. On Mon, Aug 12, 2019 at 3:13 PM Müller, Marcus (CEL) wrote: > I'd recommend looking at the spectrum you receive.

Re: [Discuss-gnuradio] 802.11a capture with HackRF - Why am I not receiving signals anymore?

I'd recommend looking at the spectrum you receive. Also, how does receiving a 20 MHz wide channel with a HackRF work? Wasn't the maximum bandwidth of that lower? On Mon, 2019-08-12 at 15:10 -0400, Eamon Heaney wrote: > Last week, I was able to capture wifi packets in the 2.4 GHz band > (using a mo

Last week, I was able to capture wifi packets in the 2.4 GHz band (using a modified example from this repo), but now I am unable to. I'm using the same .grc flowchart, with the sample rate and bandwidth both set to 20 MHz, and the channel frequency of 2.41
