Mac Tzu Posted May 29, 2018 Share Posted May 29, 2018 Hi Peeps, caveat i am new to sdr. i have just installed Pentoo. I have a RealTek R820T usb device. Gnu-radio works fine and the device detected. I am able get a FFT plot and Waterfall plot but i am only receiving noise in the Sub -60db to -90db range and i makes no difference if i unplug the antenna or not, ever on freq that i know have a signal (ie FM station). So there some kinda of problem rtl_test detect the device but i get this error: [R82XX] PLL not locked! i would loe some guidance on how to fix or if my prob might be something else.

Bigbiz Posted June 1, 2018 Share Posted June 1, 2018 (edited) Ignore it. Rtl_test detected device good. Same message on my machine. I google it before. Means nothing. Never used gnuradio I use sdrplay for wondows. What u have? Use zadig to install correct sdr drivers (Rtlsdr isn't a real rtlsdr ) Edited June 1, 2018 by Bigbiz Quote Link to comment Share on other sites More sharing options...

Mac Tzu Posted June 2, 2018 Author Share Posted June 2, 2018 Hey BigBiz, Thx for the reply. Gonna sounds silly but I only have windows for a work computer. I have recent got a cheap laptop and happy running linux on it. My desktop is Nix as well. I can see the device in terminal and the test programs works. I can see signal but it only seems to be background noise. This is just raw signals I haven't tried demodding anything. I have just been trying to see signal on a set Freq. Any pointers would be awesome. Quote Link to comment Share on other sites More sharing options...
