Bandwidth required for NOAA APT transmission is around 40kHz, but typically I set filter width to roughly 60kHz so it covers the whole transsmision, accounting for doppler shift. You need to adjust to filter in order to not filter out part of the transmission. Adjust the LNA (important) In my setup I need to max out LNA to 49dB in order to maximise signal strength.If you have just bought/built your antenna, test that it works first. Luckily I have brought two and was able to test. It took me a few failed attempts before I realise my antenna is actually broken. Here are a few more enhanced images from a morning pass (orbit 72489) of NOAA 18 over Sydney today: Receiving NOAA weather satellite images.

The enormous amount of time spent on the roads has made me looking into CB (Citizen Band), which is used by truck drivers for communication. I have done quite a few round trips driving between Melbourne and Sydney since the start of this year. There is another piece of software to automatically receive NOAA and Meteor satellites, I have yet to check it out.Receiving NOAA Satellite Images with RTL-SDR on Linux usr/local/bin/wxmap -T “NOAA $' | sort -n | xargs atrm
