https://github.com/pavels/spektrum https://github.com/xmikos/qspectrumanalyzer What articles are you referring to with no name or download links? Thanks for these, I found out about them few days after I asked about them here. I'm referring to articles here with the tag of spectrum analyzers. I'm r...

There are certain frequencies on my sweep whose signal strength are shown in red in RTL Scanner. I don't know if they belong to cell phones or not, what signal strength do normal cell phones signals have in frequency sweeps?

I have a Nooelec SMArt NESDR dongle, it works in Linux but it doesn't work in WIndows. I followed the installation instructions Nooelec has given on their website, I downloaded the latest version of zadiga, installed the drivers mentioned in it, downloaded CubicSDR, it was able to detect the SDR don...

Is there a list of spectrum analyzing software used on Linux? I searched this website, but the articles associated with them are more confusing than helpful, they have some paragraphs, some hyperlinks, but no name, or download link. Most of them seem for windows or other hardware. Is there any Linux...

Depends on what you mean by an SDR. Most WiFi, cellular, and mobile phone radios are SDRs internally. So you don't need to turn them into an SDR, as they already are SDRs. However the RF frequencies and modulations these SDR chips are capable of are often fixed to specifics bands and modes, and the...

The R820 is not a SDR chip it is in fact nothing to do with SDR simply a tuner. The SDR chips are analogue to digital converters, the RTL chip in RTL dongles is an ADC, could have any tuner chip in front of it, or none at all. If you really feel like modding it go ahead. Alan Thanks for this inform...

Can any RF chip be modded to turn into an sdr or only R820T? Can a person program their WiFi adapter to turn into an SDR covering frequencies upto 2.4GHz or 5GHz?

If yes, why aren't there sdrs with USB WiFi modules?
