Mac Tzu Posted May 29, 2018 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. Quote
Bigbiz Posted June 1, 2018 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
Mac Tzu Posted June 2, 2018 Author 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
