Wxtoimg image shifting3/30/2024 ![]() ![]() I suppose my dongle become damaged somehow but don't know exactly how. I don't know what can cause such issues as non-lockable PLL and troubles with NOAA reception (I think they are related to each other). ![]() Previous summer I was able to start decoding from 2-4 degrees above the horizon.Īt the same time I use GQRX quite well and can clearly hear FM broadcasting, NFM chatting and even AM broadcasting with the use of SpyVerter upconverter. 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 ). ![]()
