Signal level is awesome, AGC works fine, but PLL never locks even if satellite is flying right above my head. In glrpt I observe issue with PLL locking. This is strange because I constantly get about 40 dB SNR in GQRX for most prominent APT peaks.
I've tried to record about a dozen of NOAA passes but with no luck - my images are slanted and WXtoIMG can't do anything with that (see picture below).Īlso it says that it can't find telemetry data or complains about poor SNR ratio. I use (GQRX + Audacity)/(Arch Linux 64bit) + (WXtoIMG)/(Windows 10 64bit) combination to receive and decode NOAA images and (glrpt)/(Arch Linux 64bit) to receive and decode images from Meteor-M sats. I've successfully used it for decoding weather satellites past year. I own an RTL-SDR v3 USB dongle (official version from ).
